Our Solar System formed about 4.6 billion years ago. There are currently eight known planets in our Solar System. These planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. There are 185 known moons (natural satellites) orbiting these planets. Jupiter has the most with 79 moons, and Earth has the least with one moon, Mercury and Venus have no known moons.
All eight planets orbit the Sun. The Sun is a main-sequence star in the center of our Solar System. All the planets orbit the Sun in a counterclockwise direction when viewed from the north pole of our Sun. The shortest orbital period is Mercury, it only takes about 88 Earth days to fully orbit the Sun. The longest orbital period is Neptune. It takes Neptune over 164 Earth years to complete an orbit around the Sun.
Between 1930 and 2006, Pluto was considered the ninth planet, but the International Astronomical Union in 2006 formally defined the term planet, effectively demoting Pluto to a dwarf planet.
