THE SUN
The Sun contains roughly 99.8% of the mass of the Solar System and provides the energy that drives Earth's climate and supports life.
INNER PLANETS
Mercury, Venus, Earth and Mars are rocky terrestrial planets with solid surfaces.
GIANT PLANETS
Jupiter and Saturn are gas giants, while Uranus and Neptune are ice giants.
ASTEROID BELT
The main asteroid belt lies between the orbits of Mars and Jupiter.
KUIPER BELT
The Kuiper Belt begins beyond Neptune and contains many frozen remnants from the formation of the Solar System.
OORT CLOUD
The Oort Cloud is thought to extend far beyond the Kuiper Belt and may be the source of many long-period comets.
A VAST COSMIC NEIGHBORHOOD
The Solar System is much larger than the region occupied by the eight planets. Beyond Neptune lie the Kuiper Belt and possibly the enormous Oort Cloud. The entire system is only one tiny part of the Milky Way Galaxy.
