Orbits are Odd

Why does Earth orbit the Sun instead of the other way around?

• Because the Sun is lighter than Earth

• Because Earth is heavier than the Sun

• Because the Sun is the heaviest object in our solar system

• Because Earth is the center of the solar system

What is a galaxy?

• A single star with planets

• A group of stars, gas, and dust bound by gravity

• A black hole surrounded by planets

• A large planet orbiting a star

Why is the black hole at the center of the Milky Way not a threat to Earth?

• Because it is too small to affect Earth

• Because Earth is too far away from it

• Because it only affects stars, not planets

• Because it is not a real black hole

How does Pluto's orbit differ from the other planets?

• It is perfectly circular

• It is closer to the Sun than Mercury

• It is on the same plane as the other planets

• It crosses Neptune's orbit and is off-center

What role does gravity play in Pluto's orbit?

• It keeps Pluto stationary

• It forces Pluto into a lower orbit when near Neptune

• It has no effect on Pluto

• It makes Pluto orbit the Sun faster than other planets
