This is a list of known galaxies within 3.8 megaparsecs (12.4 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups , the M81 Group and the Centaurus A/M83 Group , and some ...
The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.
The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224. Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years) [8] and is approximately 765 kpc (2.5 million light-years) from ...
The galaxy's strange morphology is generally recognized as the result of a merger between two smaller galaxies.

This is a list of the nearest supergiant stars to Earth, located at a distance of up to 1,100 light-years (340 parsecs) from Earth. Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list.
The disputed dwarf galaxy Canis Major Overdensity is even closer at 25,000 light-years.

Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus. [3] For comparison, the nearest star to the Sun (Proxima Centauri) is about 4.24 light years away, and the Milky Way galaxy is approximately 100,000 light years in diameter.
At the time of its announcement, the Canis Major Dwarf Galaxy was classified as an irregular galaxy and was thought to be the closest neighboring galaxy to the Earth's location in the Milky Way, located about 25,000 light-years (7.7 kiloparsecs) away from the Solar System [2] and 42,000 ly (13 kpc) from the Galactic Center.
