Depends on the mass of the planet, its speed and the mass of the sun. Our planets revolve because they have the right speed and mass to revolve steadily.
Two factors that affect a planets revolution are distance from the sun and size.
revolution
the planets
The planets are not all the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.

This is called orbiting. Or a revolution.
The planets revolve around the sun. The moon revolves around Earth.

By the gravity of the sun.
The farther it is from the sun the longer its period of revolution (its "year").

The planets revolve around the sun. The planets rotate on their own axis.
How does a planet's distance from the sun affect its period of revolution?
