Question

How close is the nearest galaxy to us?

Answer 1

Hint:In order to answer the given question we need to have a clear knowledge about the universe, the planets, and the solar system. This question is totally based on our knowledge about the universe. So, based on our knowledge about the universe and the galaxies we can easily answer the given question.

Complete step by step answer:
Step one
We know that the galaxy in which we are is known as the MILKY WAY. So, we need to find the nearest galaxy to the MILKY WAY. We should also know this fact that our galaxy, the MILKY WAY also has a black hole at its centre.
Step two
According to the data collected by calculating the distance from the MILKY WAY, the Canis Major Dwarf Galaxy is the closest known galaxy to us. It is at a distance of $25000$ light years from the Sun. After that the next closest galaxy to our MILKY WAY is Sagittarius Dwarf Elliptical Galaxy which is at a distance of $70000$ light years from the Sun.
Hence, we conclude that the closest galaxy to us is the Canis Major Dwarf Galaxy.

Note:
We should know this fact that earlier the Large Magellanic Cloud was considered to be the nearest galaxy to the Milky Way which is actually at a distance of $179000$ light years away from the Sun. These data about the distances are given by astronomers who use different methods to determine the distances to get more accurate values of the distances measured by them.
