What is Solar System?

The eight planets and their moons, dwarf planets, comets, and asteroids are all part of the solar system, a collection of celestial bodies that revolve around the Sun. The solar system, which is estimated to be 4.6 billion years old, is located in the Milky Way galaxy.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets that make up our solar system. There are two sets of planets: the four smaller, smaller and made of rock and metal inner planets, and the four bigger, larger and made of gas and ice outer planets.

The solar system also includes several dwarf planets, such as Pluto, Ceres, and Eris, as well as many smaller objects, such as comets and asteroids. These objects orbit the Sun in a region called the Kuiper Belt, which is located beyond the orbit of Neptune.

The solar system is held together by the gravitational force of the Sun, which is the dominant body in the system. The planets, dwarf planets, comets, and asteroids orbit the Sun in elliptical paths. The solar system is constantly changing, with new objects being discovered and existing objects being reclassified as our understanding of the system evolves.

The vast majority of the several hundred thousand asteroids, commonly referred to as minor planets, revolve in the relatively flat asteroid belt, which is located between Mars and Jupiter. The innumerable asteroidal pieces and other minute particles of solid matter that make up interplanetary space are often referred to as meteoroids to distinguish them from the larger asteroidal things.
