  • What is the Great Red Spot on Jupiter?

    -The Great Red Spot on Jupiter is a massive storm that has been ongoing for at least 200 years and is visible from Earth due to its size and color.

  • Why does Saturn's density allow it to float in water?

    -Saturn's density is low enough that it would float instead of sink in water if it could be placed in a large enough bathtub, due to its composition of mostly hydrogen and helium.

  • What is unique about Uranus's rotation compared to other planets?

    -Uranus is unique because it is tilted so much that it spins sideways, unlike any other planet in the solar system.

  • Why does Neptune have the longest orbit of any planet in the solar system?

    -Neptune has the longest orbit of any planet in the solar system because it is the farthest from the sun, taking over 164 years to complete one orbit.

  • What led to Pluto's reclassification from a planet to a 'dwarf planet'?

    -Pluto was reclassified from a planet to a 'dwarf planet' because it is much smaller than any other planet in the solar system and there are other similar-sized objects in space.
