1. The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun.Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
2. The solar system is host to two broad categories of planets. The four closest to the sun Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres.
The gas and ice giants Jupiter, Saturn, Uranus and Neptune — are outliers.
