  • Why do planets stay in orbit around the Sun?
    Sun's gravity
  • What constellation is the North Star (Polaris) located in?
    Ursa Minor or Little Bear
  • Why is Mars considered a prime target for NASA’s future crewed missions?
    It has signs of past liquid water, potential for life, and resources (like CO₂) that can support exploration.
  • What evidence suggests Mars once had liquid water on its surface?
    Dry riverbeds, mineral deposits, and polar ice caps.
  • How many planets are in our Solar System?
    Eight
  • Which planet is tilted on its side (rotates almost horizontally)?
    Uranus
  • What is a light-year?
    The distance light travels in one year
  • Which constellation is known as the Hunter?
    Orion
  • Which planet has the fastest rotation (shortest day)?
    Jupiter
  • What is a supernova?
    A powerful stellar explosion at the end of a massive star’s life
  • Which constellation was used by ancient Egyptians to align the pyramids?
    Orion or Orion's Belt
  • Who was the first human to walk on the Moon and when?
    Neil Armstrong during Apollo 11 on July 20, 1969
  • What galaxy is closest large neighbor to the Milky Way?
    Andromeda Galaxy
  • Why do gas giants have many moons compared to inner planets?
    Their massive gravity can capture passing objects and hold large moon systems.
  • Which planet has the tallest volcano in the Solar System, Olympus Mons?
    Mars.
  • What is the Hubble Space Telescope’s main advantage over ground telescopes?
    It orbits above Earth’s atmosphere, avoiding distortion and light pollution.
  • What’s the difference between rotation and revolution?
    Rotation is spinning on an axis while revolution is orbiting the sun
  • Which NASA program first landed humans on the Moon?
    Apollo Program
  • Why do outer planets have longer orbital periods than inner planets?
    They are farther from the Sun
  • Which planet has a day (rotation) longer than its year (orbit)?
    Venus
  • What is meant by a planet’s “escape velocity”?
    The minimum speed needed to escape the planet’s gravitational pull
  • Why is Venus hotter than Mercury even though it is farther from the Sun?
    Because of its thick carbon dioxide atmosphere
  • What does NASA stand for?
    National Aeronautics and Space Administration.
  • What is the Big Bang?
    The rapid expansion that began the universe about 13.8 billion years ago.
  • What does a rocket need to overcome to reach space?
    Earth’s gravity
