All tiny bright things above your head

Kids do you know what are several luminous objects that shines over your head in night sky? 

Stars, planets, and galaxies are all part of the vast universe we live in. They are distinct astronomical objects, each with their own unique properties and characteristics. 

A star is a massive, luminous ball of gas that generates heat and light through nuclear fusion in its core. Stars come in a range of sizes, from tiny red dwarfs to supergiant stars that are hundreds of times larger than the Sun. Stars are the building blocks of galaxies and play a crucial role in the evolution of the universe. 

A planet is a celestial body that orbits around a star and is massive enough to have its own gravity, which gives it a round shape. There are eight planets in our solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Planets can be rocky, like Earth and Mars, or gaseous, like Jupiter and Saturn. 

A galaxy is a large system of stars, dust, and gas held together by gravity. There are billions of galaxies in the observable universe, each containing millions or billions of stars. Galaxies come in different shapes and sizes, including spiral galaxies like the Milky Way, elliptical galaxies, and irregular galaxies. 

Together, stars, planets, and galaxies make up the fascinating and complex universe we live in, and studying them can help us better understand the nature of the cosmos and our place in it.
