Solar System

The solar system is a collection of celestial bodies, including the sun, planets, moons, asteroids, comets, and other objects that orbit the sun. The sun is at the center of the solar system, and all the other objects orbit around it due to its gravitational pull.

Sun

The sun is a massive, luminous sphere of hot plasma that is the star at the center of the solar system. It provides light and heat to the planets and other objects in the solar system.

Planets

There are eight planets in the solar system, divided into two groups: terrestrial planets (Mercury, Venus, Earth, and Mars) and gas giants (Jupiter, Saturn, Uranus, and Neptune). The planets vary in size, composition, and distance from the sun.

Moons

Many of the planets in the solar system have moons or natural satellites that orbit around them. For example, Earth has one moon, while Jupiter has over 70 moons.

Asteroids and Comets

Asteroids are small, rocky objects that orbit the sun, mostly found in the asteroid belt between Mars and Jupiter. Comets are icy bodies that also orbit the sun, and they are known for their bright, glowing tails when they approach the sun.
