Which word describes how the planet are held in Earth's solar system together? (1 point)

an atomic force
gravity
a tidal force
friction

gravity

The word that describes how the planets are held together in Earth's solar system is gravity. Gravity is the force of attraction between objects with mass. In the case of planets in the solar system, they are held in their orbits around the Sun by the gravitational pull between the Sun and the planets.

To answer this question, you can recall basic knowledge about the solar system and planetary motion. You may even remember learning about the laws of motion and gravity in physics or astronomy classes. The understanding of gravity as a force of attraction between objects with mass should help you choose the correct answer, which in this case is gravity.

The correct answer is "gravity." Gravity is the force that holds the planets in Earth's solar system together.
