The Earth in the Solar System

Celestial Bodies – The Sun Moon and all those things that shine in the sky at night are called celestial bodies. Some celestial bodies are large and hot. They are made of gases. They have their own heat and light which they emit in very large quantities. These celestial bodies are called stars.

The sun is also a star

Some celestial bodies do not have their own light and heat, they are illuminated by the light of stars, such bodies are called Planets.

Earth is also a planet which receives all its light and heat from the Sun, which is the nearest star to the Earth.

The moon is a natural satellite. It is the companion of our earth and surrounds it.

Solar System

The solar system consists of eight planets, satellites and some other celestial bodies such as asteroids and meteorites.

The Sun is located in the center of the Solar System. It is very large and is made up of extremely hot gases. The only source of light and heat for the Solar System. The Sun is about 150 million kilometers away from the Earth.

There are eight planets in our solar system, according to distance from Sun to Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranas and Neptune.

All the eight planets of the Solar System orbit the Sun on a fixed path. These paths are spread across the ellipsoid. These are called class. Mercury is closest to the Sun. It takes only 7 days to orbit the sun in its orbit.

Earth is the third planet according to the distance from the Sun. It is the fifth largest planet in size. Earth looks blue when viewed from space because two thirds of its surface is covered with water.

Conditions favorable for life are found only on the earth. The earth is neither too hot nor too cold. Water and air are present here which is essential for our life.

Our Earth has only one satellite, the Moon. Its diameter is only one fourth of the diameter of the Earth, the moon completes one round of the Earth in about 24 days.

Moon conditions are not favorable for life

Besides the stars, planets and satellites, there many small bodies also move around in the Sun. These bodies are called asteroids. They are located between the orbits of Mars and Jupiter.

Small pieces of rock that move around the sun are called meteoroids. Sometimes these meteors come close to the earth and tend to fall on it. During this process due to friction with the air are heated and burned. It causes a flash of light. Sometimes a meteor without being completely burnt, falls on the earth and creates a hollow.
