Question

Fill in the blanks
_______is the closest celestial body to earth.

Answer 1

Hint:Our earth is the third closest planet to the Sun. With two thirds of its surface under water and an atmosphere rich in nitrogen and oxygen, Earth is the only planet that can support life.

Complete answer:A celestial body includes planets, moon, stars and other natural objects which are found in space. They are also known as astronomical objects. These planets, stars, comets, meteors, satellites and galaxies form the larger universe that we are part of.

The moon is the celestial body closest to earth. The moon is at a distance of 384400km from Earth. It is our planet’s only natural satellite.
One of the theories explaining the formation of Earth’s moon is that it was formed after a collision between Earth and a Mars-like planetary object.
Moon has a very thin atmosphere and its gravity is one sixth of Earth’s.
Earth and the moon rotate at the same rate and as their rotations are in sync, we only see one side of the moon from earth.
The moon helps to stabilize our climate, lengthens our days slightly and influences the oceanic tides.

The moon is the closest celestial body to earth and is the only celestial body where man has set foot.
Therefore, the correct answer is moon.

Note:It is to be noted that Earth’s moon is Earth’s only natural satellite. A satellite is a smaller object orbiting a larger celestial body. Earth has only one permanent natural satellite ( the moon) but has many artificial-man made satellites too. Soviet Union sent the first man made satellite to space-Sputnik 1.
Another important fact to remember is that the first definitive discovery of water on the Moon was made by Indian lunar mission -Chandrayan 1- in 2008.
