What is Solar System?

The solar system describes the arrangement of Earth and other planets relative to the sun. It consists of the sun and nine planets, all orbiting the sun in elliptical paths.

The universe comprises numerous celestial bodies, and stars form clusters called galaxies or nebulas. Our local galaxy, the Milky Way, includes twenty-seven galaxies.

A satellite is a smaller celestial body orbiting a planet, and Earth’s natural satellite is the moon.
