All about Space

Space is the most unexplored and mysterious sphere for scientists. And what do you know about space? How many planets can you name? Stars are not solid planets. They are just spheres of hot gas, like the sun. Did you know that it is also a star? Large clusters of stars people call galaxies. Our home galaxy consists of more than two hundred stars. It is named the Milky Way; under a telescope it looks like spilt milk. The Sun is also a huge ball of gas. It holds the entire solar system in place, due to its gravity. If the sun ever goes out, the planets will fly into space and the flight path cannot be predicted. Earth makes a revolution around the Sun per year. Thanks to this that the planet gets colder and warmer at different times of the year. And thanks to the rotation of the planet, day and night replace each other.
