How far away will we have to travel to leave the Milky Way galaxy?

How far away will we have to fly to leave our galaxy?

The Solar System is located halfway between the center and the edge of the disk, in the region of the Orion Arm.

Are you tired of sitting at home? Why not take a trip around our Galaxy, or watch the colorful views of the Milky Way from the outside?

It will depend on where in the Galaxy you would like to be. The size of the Galaxy is impressive, although it is not the largest Galaxy in the universe, but its size is huge - thousands of light years, for more beautiful views and to observe the Galaxy from the outside we would have to go even further.

The Milky Way Galaxy, home to the Solar System, is a star disk about one hundred thousand light years wide and an average estimated thickness of the disk about one thousand light years.

Our Solar System is located approximately halfway from the center to the edge of the Galaxy and is almost in the middle of the galaxy's star disk in the vertical direction.

It is not difficult to calculate that it will take at least 500 light-years to leave our Galaxy, or take the longest route and spend about 25,000 light-years.

Will we thus reach the end of our Galaxy? I don't think so! Outside the boundaries of the stellar disk, the Galaxy's companions are waiting for us: a halo of hot, low temperature gas, old, cooling stars and stellar balloons.

After all, if we want to enjoy all the beauty of the Milky Way from the outside, for example, the way the Andromeda Nebula is presented to us, following the shortest route, we will have to overcome an additional 48,000 light years.

It will be many more years before we have the technology to transport us over vast distances in a short period of time, but for now we must enjoy the incredible images of other space objects and galaxies that our ground and space telescopes provide.

What is the Milky Way galaxy?


The Milky Way is a spiral galaxy, of which the Solar System is part. Viewed from the Earth, it appears as a bright, diffuse strip that surrounds the entire celestial sphere, cut out by molecular clouds that give it an intricate, irregular and jagged appearance. Its visibility is severely compromised by light pollution. With a few exceptions, all objects visible to the naked eye belong to this galaxy.

What is the Andromeda galaxy?


The Andromeda Galaxy (also known as Messier 31, M31 or NGC 224, and formerly the Great Nebula in Andromeda) - a spiral galaxy that lies approximately 2.52 million light years from Earth in the constellation of Andromeda.

Until recently, the Andromeda Galaxy was thought to be the most massive galaxy in the Local Group, which also includes the Milky Way, the Triangulum galaxy and about 50 smaller galaxies. Currently, based on more recent observational data, it is believed that the Milky Way contains more dark matter and may be the most massive object in the group. However, the Andromeda galaxy has many more stars, and observations with the Spitzer Telescope allow us to estimate their number at about a trillion.
