A planet is an astronomical object orbiting a star or a stellar remnant. It is rounded by its own gravity. The planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Our star is called the Sun.
In our solar system, Jupiter is the largest planet and Mercury is the smallest. Mercury is nearest to the Sun and Neptune is the farthest.
Our planet Earth is third from the sun and the only planet known to exist life. You may have heard about Aliens-people from other planets but there is not enough evidence to prove that they really exist.
