The solar system is a gravitationally bound system of the Sun and the objects that orbit it, including:
Planets: Eight major planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
Dwarf planets: Five officially named dwarf planets: Ceres, Pluto, Haumea, Makemake, and Eris (Coming Soon)
Moons: Hundreds of moons orbiting planets, dwarf planets, and asteroids
Asteroids: Thousands of asteroids
Comets: Thousands of comets
Kuiper Belt: A ring of icy bodies that lies past Neptune's orbit
The solar system formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed. It's located in the Milky Way, a barred spiral galaxy, in a small arm called the Orion Arm. The solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph) and takes about 230 million years to complete one orbit.
The name "solar system" comes from the Latin word for Sun, solis, which is used to describe things related to our star.
Here are some other facts about the solar system:
The four closest planets to the Sun are small, rocky planets.
The asteroid belt is located beyond Mars and is populated by millions of rocky objects.
NASA is searching for life on other worlds in our solar system and beyond.
