Question

Name the galaxy in which we reside.

Answer 1

Hint: A galaxy is defined as a big group of stars, gas, and the dust which is bound together by gravity. They are seen in so many different shapes and sizes. The Milky Way is one among the galaxy which is a large barred spiral galaxy. All the stars which are visible for us in the sky at night are in our Milky Way Galaxy. This all will help you in answering this question.

Complete answer:
The Sun which is also a star and all the other planets around it are included in a galaxy called the Milky Way Galaxy. This galaxy is known as the Milky Way as it looks like a milky band of light in the sky when we view it from a really dark area. It is nearly impossible to count the number of stars in the Milky Way by staying at our position inside the galaxy. The studies give an estimate which tells us that the Milky Way is made up of around hundred billion stars. These stars will make a large disk which is having a diameter of about one lakh light years. Therefore the galaxy in which we reside is the Milky Way galaxy .

Note:
Our Solar System is estimated to be twenty five thousand light years away from the centre of our galaxy. That means we are residing in the suburbs of our galaxy. As we already know the Earth is making revolutions around the Sun. In the same way the Sun is also revolving around the centre of the Milky Way.
