    What is solar system 

The solar system refers to the Sun and all the celestial bodies that orbit it. This includes eight planets, dwarf planets, moons, asteroids, comets, and other space objects that are all bound by the Sun's gravity. The eight planets in our solar system, in order from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The study of our solar system is known as solar system astronomy.

Here are some of the important facts of solar system.

The Sun is the center of the solar system and contains over 99.8% of its total mass.

The eight planets in order from the Sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Pluto was once considered a planet but is now classified as a dwarf planet.

The asteroid belt is located between Mars and Jupiter and contains millions of rocky objects.

Kuiper Belt is located beyond Neptune and contains many icy objects, including dwarf planets such as Pluto.

The Oort Cloud surrounds the solar system and is believed to contain trillions of comets.

The average distance between the Sun and Earth is 93 million miles or 150 million kilometers.

The speed of light is an important constant in solar system astronomy and is approximately 186,000 miles per second or 299,792,458 meters per second.

The astronomical unit (AU) is used to describe distances within the solar system. One AU is the average distance between the Sun and Earth, about 93 million miles or 149.6 million kilometers.

The period of revolution (orbital period) for each planet, or the time it takes to complete one orbit around the Sun, varies greatly. For example, Mercury takes 88 Earth days to orbit the Sun, while Neptune takes nearly 165 Earth years.

The solar system's age is estimated to be around 4.6 billion years old.
