Journey to the Andromeda Galaxy
The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years (2.4×1019 km) from Earth in the Andromeda constellation. Also known as Messier 31, M31, or NGC 224. No, Andromeda is not our closes galaxy. There are satellite galaxies to our Milky way such as the Large and Small Magellanic clouds. However, besides these satellite galaxies, Andromeda is the nearest.
The diameter of our Milky Way, is 100,000 LY which means that light would need to go at 186,000 miles per second for 100,000 years, in order to travel from one edge of the galaxy to the other. The Andromeda Galaxy's diameter is twice that width. It also contains twice the number of stars more than our Milky which has approx. 200–400 billion. Both galaxies are expected to collide in approx. 3.4 billion years, and will merge into a new galaxy.
