KOMPAS.com – A galaxy is one of the systems of stars and interstellar matter that make up the universe.
According to the Encyclopedia Britannica, one of the popular galaxies is the Andromeda Galaxy, which is a large spiral galaxy in the constellation Andromeda.
The Andromeda Galaxy is one of the few galaxies visible to the naked eye and appears opaque to the color of milk.
As the closest spiral galaxy to Earth, Andromeda is located about 2,480,000 light years from Earth, with a diameter of about 200,000 light years.

Travel to the nearest galaxy
How long it takes a spacecraft to travel to the nearest galaxy from Earth depends on the speed at which it travels.
However, according to Cool Cosmos, in general, it takes a very, very long time to reach the nearest galaxy.
The closest large galaxy is the spiral galaxy Andromeda. As already mentioned, this galaxy is about 2.5 million light years from Earth.
One light year is the distance light travels in one year in a vacuum at 186,000 miles per second. So, we can be sure that it will take a very long time to reach the nearest galaxy.

Besides Andromeda, the other galaxy closest to Earth is the Canis Major Dwarf Galaxy, which is a member of the Local Group of galaxies.
The Canis Major Dwarf galaxy was discovered in 2003 by a team of astronomers from France, Italy, Australia and the United Kingdom who were involved in the Two-Micron All Sky Survey (2MASS), a project that began in the late 1990s.
The Canis Major Dwarf galaxy is located about 25,000 light years from Earth’s solar system and about 42,000 light years from the center of the Milky Way.
