Mercury

Mercury is the planet nearest to the sun. it turns around the sun once every 88 days.

Because this planet lies so close to the Sun, and as a result somewhat near to the Earth, it is visible to observers on Earth in the night time sky.

The Sun

The Sun is the star at the center of the Solar System. It gives energy in form of sunlight that provides light and supports almost all life on Earth by photosynthesis, it also drives Earth's climate and weather.

The Sun is by far the largest object in the Solar System. 98% of all matter within the Solar System is found within the Sun. This means that all the planets, moons, asteroids, minor planets, comets, gas, and dust would all combine to make up only 2% of all the matter in the Solar System.
Because the Sun is so large compared to everything else, it is easily able to hold on to the rest of the matter, causing everything else to orbit around it.

The Moon

The earth is the third planet away from the sun, and it is the eight largest planets. It is the only place in the Universe where life exists, home to millions of species, including humans. It has water in abundance. It turns around the sun every 365.25 days.

It is sometimes referred to as the Blue Planet or the World.

The Solar System

The solar system is composed of nine planets of different nature and sizes. The Sun is the nearest star and source of the energy. The rest nineplanets are Mercury , Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The sun is in the middle and all the planets rotate around it in a relatively circular orbit. Our planet earth is thus far the only planet that life is found, scientists has been trying to discover life on other planets but thus far have not been successful.
