Solar System Test

Why does the Sun have the strongest gravitational pull in the solar system?

• It is the hottest object in the solar system.

• It is the largest and most massive object in the solar system.

• It is made of burning gases instead of solid matter.

• It spins faster than any planet.

Why do gas giants like Jupiter have more moons than rocky planets like Earth?

• They are farther from the Sun, so they attract more objects.

• They have more gravity because they are larger and more massive.

• They spin faster, which helps them capture more moons.

• They have thicker atmospheres, which hold moons in orbit.

What evidence helped scientists determine that the heliocentric model of the solar system was correct?

• The Sun rises in the east and sets in the west.

• Planets and stars appear to move across the sky at night.

• Telescopes allowed scientists to observe planets orbiting the Sun.

• The Moon orbits Earth instead of the Sun.

If you wanted to find a newly discovered asteroid, where would you be most likely to look?

• Near Earth's atmosphere, since most asteroids travel close to our planet.

• In the asteroid belt between Mars and Jupiter.

• Orbiting Jupiter, since it is the largest planet.

• In the Sun’s atmosphere, since strong gravity attracts small objects.

What is the main reason Pluto was reclassified as a dwarf planet?

• It is too far from the Sun to be considered a planet.

• It has an irregular shape.

• It does not have enough gravity to clear its orbit of other objects.

• It does not have any moons.

If the Sun were twice its current size, what would most likely happen to the planets?

• They would stop orbiting and drift into space.

• They would orbit faster and move closer to the Sun.

• Their orbits would not change because mass does not affect gravity.

Which planet is NOT one of the

"Gas Giants"?

• Uranus

• Venus

• Neptune

• Saturn

It takes Neptune 164 ____to orbit the sun because it is so far away.

• days

• years

• decades

• centuries

Which of the following best describes how gravity affects the motion of objects in the Solar System?

• Gravity only affects objects on Earth.

• Gravity pulls objects towards the center of the Earth.

• Gravity keeps planets in orbit around the Sun.

• Gravity has no effect on the motion of objects in space.
