Did You Know?
  1. China's Chang'e-6 robotic spacecraft recently brought back lunar soil samples that contained fragments of volcanic rock dating back to 4.2 billion years; the Chang'e-6 probe used a scoop and drill to obtain about 1,935 grams of soil, containing more than 100 basalt fragments. This finding, which is remarkable that a piece of this old rock has assisted scientists in uncovering more about the moon’s history, helps solve the mystery of why the moon's far side is so different from its near side, which has more visible volcanic plains.
  2. Earth is the third planet from the Sun and the largest of the terrestrial planets, which include Mercury, Venus, Earth, and Mars; Earth is the only known planet to support life.
    • Name: The name Earth is at least 1,000 years old; all of the planets, except for Earth, were named after Greek and Roman gods and goddesses; however, the name Earth is a Germanic word, which simply means “the ground.”; there are, of course, many names for our planet in the thousands of languages spoken by the people of the third planet from the Sun.
    • Liquid Water: Earth is the only known planet to have liquid water on its surface, which is essential for life.
    • Age and Formation: Earth formed about 4.54 billion years ago; life appeared around 3.8 billion years ago, and humans have been around for only about 6 million years.
    • Speedy Traveler: Earth orbits the Sun at an average speed of about 107,182 kilometers per hour (66,627 miles per hour).
    • Day and Year: A day on Earth is 23.9 hours long, and it takes 365.25 days to complete one orbit around the Sun, which is why we have a leap year every four years.
    • Tilt and Seasons: Earth’s axis is tilted at 23.4 degrees, which causes the seasons; as Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight; the rotation of the Earth is gradually slowing down.
    • Cosmic Dust: Earth receives between 100 and 300 metric tons of cosmic dust every day.
    • Exploration: Despite being covered by over 70% water, more than 95% of Earth’s oceans remain unexplored.
    • Gravity: The gravity between the Earth and the Moon causes the tides on Earth; the Hudson Bay region in Canada has slightly less gravity than other parts of the planet, and the reasons behind this anomaly are unknown.
  3. Earth is the only planet that has a single moon that stabilizes Earth's wobble, which has made our climate less variable over thousands of years.
  4. Earth and Mars orbit the Sun; but Earth is closer to the sun, and therefore races along its orbit more quickly. Earth makes two trips around the Sun in about the same amount of time that Mars takes to make one trip.
  5. The Moon is a rocky, cratered place, roughly a quarter the size of Earth and an average of 238,855 miles away.
    • Formation and Age: The Moon formed about 4.6 billion years ago, around the same time as the Earth.
    • Size and Distance: Earth has just one moon; the Moon is about one-quarter the size of Earth, with a diameter of 2,160 miles (3,476 kilometers); the Moon orbits Earth at an average distance of 238,900 miles (384,000 kilometers).
    • Visibility: The Moon can be seen with the naked eye most nights as it traces its 27-day orbit around our planet; the Moon does not shine with its own light, it simply reflects light coming from the Sun.
    • Synchronous Rotation: The Moon is tidally locked with Earth, meaning we always see the same side of it from our planet.
    • Gravity: The Moon’s gravity is about one-sixth that of Earth’s. This is why astronauts can take giant leaps on its surface.
    • No Atmosphere: The Moon has no atmosphere, which means there is no weather, and the sky always appears black.
    • Tides: The gravitational pull of the Moon causes the rise and fall of tides on Earth.
    • Drifting Away: The Moon is slowly drifting away from Earth at a rate of about 3.8 centimeters per year.
    • Lunar Quakes: The Moon experiences quakes, known as moonquakes, caused by the gravitational pull of Earth.
    • Exploration: Only 12 people, all American men, have walked on the Moon; the first was Neil Armstrong in 1969 during the Apollo 11 mission.
    • Natural Satellite: The Moon is Earth’s only natural satellite and one that we can easily see most nights.
  6. The Sun is truly an incredible and vital part of the solar system.
    • Age: The Sun is about 4.5 billion years old and is classified as a yellow dwarf star.
    • Composition: The Sun is a hot bright ball of hydrogen and helium at the center of our solar system, and it is becoming increasingly hotter (or more luminous) with time; the Sun is primarily composed of hydrogen (about 75%) and helium (about 24%) with trace amounts of other elements.
    • Size and Mass: The Sun’s diameter is approximately 864,000 miles (1,392,000 kilometers), making it about 100 times wider than Earth; about 1.3 million Earths could fit inside the Sun; the Sun accounts for 99.86% of the total mass of our solar system.
    • Distance from Earth: The Sun is about 93 million miles (150 million kilometers) away from Earth; this distance is known as an astronomical unit (AU) and is used to measure distances within our solar system.
    • Energy Production: The Sun’s core temperature reaches about 27 million degrees Fahrenheit (15 million degrees Celsius); this intense heat enables nuclear fusion, where hydrogen atoms fuse to form helium, releasing vast amounts of energy.
    • Rotation: The Sun rotates on its axis, but not uniformly; its equator completes one rotation in about 25 Earth days while its poles take about 36 Earth days.
    • Solar Activity: The Sun exhibits various dynamic activities, including solar flares and coronal mass ejections; these events release significant energy and particles into space, sometimes affecting Earth’s magnetic field and communication systems.
    • Lifecycle: Currently, the Sun is in the middle of its lifecycle; within around 5 billion years, it will expand into a red giant before shedding its outer layers and leaving behind a dense core known as a white dwarf.
  7. Mars is a fascinating planet and is often called the “Red Planet” because of its reddish appearance, which is due to iron oxide (rust) on its surface.
    • Thin Atmosphere: Mars has a very thin atmosphere composed mostly of carbon dioxide, with traces of nitrogen and argon.
    • Moons: Mars has two small moons, Phobos and Deimos, which are thought to be captured asteroids.
    • Size and Distance: Mars has a radius of about 2,106 miles (3,390 kilometers), making it roughly half the size of Earth. It is about 142 million miles (228 million kilometers) away from the Sun.
    • Seasons and Days: A day on Mars, called a “sol,” is about 24.6 hours long, very similar to an Earth day. However, a year on Mars lasts 687 Earth days.
    • Water Ice: Mars has polar ice caps made of water and dry ice (frozen carbon dioxide). There is also evidence that liquid water once flowed on its surface.
    • Largest Volcano: Olympus Mons on Mars is the tallest volcano in the solar system, standing about 13.6 miles (22 kilometers) high.
    • Tallest Mountain: Mars is home to the tallest mountain in the solar system.
    • Dust Storms: Mars experiences the largest dust storms in the solar system, which can cover the entire planet and last for months.
  8. About 4.5 billion years ago, a Mars-sized object a series of many smaller objects crashed into Earth, sending bits of Earth's crust into space. They fell into the planet's orbit and eventually coalesced, forming our moon, which was around 16 times closer to the Earth than it is today. Each year, the moon moves at a rate of 3.8 centimeters (1.5 inches) from the Earth since.
  9. Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury; Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. The journey from Earth to Mars takes about 300 days; every two years Mars is at its closest point, only 55 million km from Earth
  10. Stars are truly incredible celestial objects that play a crucial role in the universe. Stars are giant balls of hot gas held together by gravity – primarily made of hydrogen with some helium and small amounts of other elements.
    • Life Cycle: Stars have life cycles that can range from a few million to trillions of years; their properties change as they age.
    • Visibility: On a clear, dark night, you can see about 2,000 to 2,500 stars with the naked eye from any given place on Earth.
    • Temperature and Color: The color of a star indicates its temperature; red stars are the coolest while blue stars are the hottest.
    • Star Formation: Stars form in clouds of gas and dust called nebulae; the process begins when these clouds are disturbed, often by a nearby supernova explosion.
    • Mass and Lifespan: The more massive a star, the shorter its lifespan; massive stars may live only tens of millions of years while smaller stars can shine for billions of years.
    • Sun: The Sun, the closest star from Earth, is a middle-aged star at about 4.5 billion years old; it takes about 8.5 minutes for light from the Sun to reach Earth.
    • Star Clusters: Many stars travel through the galaxy in clusters or with companions; however, the Sun moves through the galaxy alone.
    • Historical Observations: The oldest accurately dated star chart appeared in ancient Egyptian astronomy in 1534 BC; Chinese astronomers recorded the first supernova in 185 AD.
    • Distance: The furthest individual star observed is about 100 million light-years away from Earth in the M100 galaxy of the Virgo Cluster.
  11. The Pistol Star is the largest-size star, which has a mass about 100 times the mass of the Sun and a radius of about 100 million miles; the Sun is an average-sized star, and the smallest stars are less than 1/10th as massive as the Sun.
  12. NASA’s Parker Solar Probe launched from Florida Sunday, Aug. 12 2018 to begin its journey to the Sun, where it will undertake a landmark mission. The journey will send it skimming through the Sun's atmosphere at a pace of 450,000 mph — fast enough to get from Washington to New York in about a second. It will fly within 4 million miles of the Sun's surface — seven times closer than any spacecraft has gotten before. That heat shield will not only be exposed to sunlight, it must withstand blasts of 2,600 degrees Fahrenheit — while simultaneously maintaining the instruments on the other side at roughly room temperature. Parker Solar Probe will provide new data on solar activity and make critical contributions to our ability to forecast major space-weather events that impact life on Earth.
  13. The Milky Way appears as a band of light in the night sky formed from stars and contains between 100 and 400 billion stars and at least 100 billion planets, with the naked eye we can see about 4,000 stars in each hemisphere of the sky. Stars that are discovered today are in general named for where they are in the sky or the person who found them; each star usually has more than one name, there were around 300 stars were named so far.
  14. The Milky Way, which is a barred spiral galaxy that is estimated to be around 13.6 billion years old, is a dish that measures approximately 100,000 light-years in diameter. The disk is not perfectly flat though, it is warped due to our neighboring galaxies large and small magellanic clouds.
  15. The Milky Way is warped, has a halo, and produces new stars at a rate of around 7 per year. Our Earth is located roughly halfway to the edge of the Milky Way, at a distance of about 26,000 light years from the center.
  16. There are about 3 trillion trees on our planet, this means there are around 420 trees for every person on the Earth; there are 400 billion stars approximately in our own galaxy, the Milky Way.
  17. Astronomers are hunting for a "Planet Nine" after evidence of its existence was unveiled on Jan. 20, 2016. This undiscovered super-Earth-sized planet would have an estimated mass of ten Earths, a diameter two to four times that of Earth, 5,000 times the mass of Pluto, and an elongated orbit lasting approximately 15,000 years.
  18. Venus was the first planet explored by a spacecraft and was intensely studied early in the history of space exploration. Venus was also the first planet whose surface was reached by a spacecraft from Earth. NASA’s Parker Solar Probe has made multiple flybys of Venus. On Feb. 9, 2022, NASA announced the spacecraft had captured its first visible light images of the surface of Venus from space during its February 2021 flyby.
  19. Venus is the second closest planet to the Sun, orbiting at a distance of about 67 million miles (108 million kilometers). It has a solid surface covered in dome-like volcanoes, rifts, and mountains, with expansive volcanic plains and vast, ridged plateaus. Venus is permanently shrouded in thick, toxic clouds of sulfuric acid that start at an altitude of 28 to 43 miles (45 to 70 kilometers). The clouds smell like rotten eggs!.
  20. Venus, which has a surface temperature of around 900 degrees Fahrenheit (475 degrees Celsius), is the hottest planet in the solar system with surface temperatures hot enough to melt lead. The intense heat means landers have only survived for a couple of hours.
  21. Venus is the second planet from the Sun and is Earth’s closest planetary neighbor. Venus rotates on its axis backward, compared to most of the other planets in the solar system. This means that, on Venus, the Sun rises in the west and sets in the east, opposite to what we experience on Earth. Venus has a slow axis rotation which takes 243 Earth days to complete its day. The orbit of Venus around the Sun is 225 Earth days, making a year on Venus 18 days less than a day on Venus.
  22. There is no atmosphere in space; space has no air, it is a vacuum; sound waves cannot travel through a vacuum and therefore no sound in space. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.
