Solar System

I just think that we need to know where we ‘re living right now. I can’t write about the Milky Way Galaxy because it’s  humongous. So, I will start by talking about the Solar System. We learnt about it in elementary school, the solar system consists of a star, eight planets, their moons,  and other objects that orbiting around it. It includes many other objects that revolve around the sun, such as asteroids, meteoroids, and comets; and a thin cloud of gas and dust known as the interplanetary  medium. 

Since the 1990’s, astronomers have discovered many planets, though the planets cannot be seen directly. But  by studying the masses and the orbits of these planets, astronomers hope to learn about solar system even more in general.

For your information, several other stars have disk-shaped clouds around them that seem to be developing solar systems. In 1893, an infrared telescope in space photographed such a disk around Vega, it is the name of a star too if you don’t know. This discovery represented the first direct evidence of such material around any stars except the sun. By early 2000’s, astronomers had discovered that more that 50 stars like our sun have planets orbiting them.
