The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies.
The Inner Solar System is the region of space surrounding the Sun up to the asteroid belt. It includes the planets Mercury, Venus, Earth, Mars, and the dwarf planet Ceres. All of the planets in the Inner Solar System are made of rock and metal, with the exception of Venus, which is mostly made of gas and has a very hot surface. The asteroids in the asteroid belt are also made of rock and metal.
Mercury is the smallest planet in our solar system and is also the closest planet to the sun.
ViewVenus is the second planet from the Sun and the closest planet to Earth. It is the brightest natural object in the night sky after the Moon.
ViewThe Earth is the third planet from the Sun and the only astronomical body known to harbor life.
ViewMars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury.
ViewThe outer solar system is the region of the solar system that extends beyond the asteroid belt. It consists of the gas giants Jupiter, Saturn, Uranus, and Neptune, as well as the dwarf planet Pluto. The outer solar system is also home to many of the solar system's moons, including the Galilean moons of Jupiter, the Saturnian moons, the Uranian moons, and the Neptunian moons. The outer solar system is thought to have formed through the gravitational collapse of a giant molecular cloud.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
ViewSaturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter.
ViewUranus is the seventh planet from the Sun. It is the third-largest planet in the Solar System, after Jupiter and Saturn.
ViewNeptune is the eighth and farthest known planet from the Sun in the Solar System.
