Which of the following best describes the role of gravity in maintaining the structure of the solar system?

Gravity keeps the planets and other objects in orbit around the sun.

Explain why the outer planets take longer to orbit the sun compared to the inner planets.

The outer planets have a greater distance to travel and experience a weaker gravitational pull from the sun, resulting in longer orbital periods.

The greater the mass of an object, the stronger its gravitational force.

I can model how gravity holds the solar system together.

1
The solar system formed from a nebula about 4.6 billion years ago, with gravity flattening the material into a disc and forming the Sun at the center.
2
The solar system consists of the sun and all the objects that orbit it, including eight planets divided by the asteroid belt: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
3
The four inner, or terrestrial, planets have solid, rocky surfaces, while the outer planets are gas giants made of gases and liquids, with many moons and rings.
