Solar System

Our Solar System contains mainly our sun and the eight planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Pluto, once considered a planet, is now classified as a dwarf planet. Other dwarf planets include Ceres, Haumea, Makemake, and Eris.

Additionally, there is the asteroid belt between Mars and Jupiter, many moons orbiting the planets, lots of comets, the Kuiper belt, and the Oort cloud on the outer rim.

The space between these cosmic bodies is near vacuum, with solar wind and solar radiation decreasing towards outer space.
