The Solar System has 8 planets orbiting the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. They split into rocky inner planets (Mercury to Mars) and gas giants (Jupiter to Neptune).
A planet's year is how long it takes to orbit the Sun once. Mercury's year is just 88 Earth days. Neptune's year is 165 Earth years! The further from the Sun, the longer the year.
