Planets and Orbit

What is true about the distance between a planet and the sun and the planet’s revolution around the Sun?

• The closer the planet is to the sun, the slower it orbits.

• The farther the planet is to the sun, the faster it orbits.

• The farther the planet is to the sun, the brighter the sun is.

• The closer the planet is to the sun, the faster it orbits.
