Gravity in the Solar System

What is the main reason the planets in our Solar System do not crash into the Sun?

• The Sun's gravity is weak.

• The planets are moving very fast sideways.

• The planets are stationary.

• The Sun repels the planets.

Which object in our Solar System has the most mass?

• Earth

• Jupiter

• The Sun

• Saturn

Why does the Earth's gravity keep the Moon in orbit around it?

• The Moon is very close to the Earth.

• The Earth's gravity is strong enough to hold onto the Moon.

• The Moon has no gravity of its own.

• The Sun's gravity has no effect on the Moon.

What happens to the gravitational pull as you move farther away from an object?

• It gets stronger.

• It stays the same.

• It gets weaker.

• It disappears completely.

Why do giant planets like Jupiter and Saturn have many moons?

• They are closer to the Sun.

• They have strong gravity that can hold onto many moons.

• They are made of gas.

• They have no atmosphere.
