Natalie is reading an article about objects in the solar system. She finds out that Ganymede, one of Jupiter's moons, is bigger than the planet Mercury. Which statement explains why Ganymede is not classified as a planet?

• It is not as close to the Sun as Mercury.

• It orbits Jupiter and not the Sun.

• It is not shaped like the rest of the planets.

• It is held in orbit by gravity.

The force that holds all of the planets in orbit around the sun is _______.

• friction

• magnetism

• stickiness
