The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
The solar system has one star, eight planets, five dwarf planets, at least 290 planetary moons, about 1.4 million asteroids, and about 4,000 comets (including fragments). Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms.

The solar system includes the Sun, eight planets, five named dwarf planets, and hundreds of moons, asteroids, and comets. Our solar system is located in the Orion spur of the Milky Way, a barred spiral galaxy that's about 100,000 light years across.
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris.
