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 ...

The Milky Way's spiral structure is uncertain, and there is currently no consensus on the nature of the Milky Way's arms. [212] Perfect logarithmic spiral patterns only crudely describe features near the Sun, [210] [213] because galaxies commonly have arms that branch, merge, twist unexpectedly, and feature a degree of irregularity.
It is the closest non-satellite galaxy to the Milky Way, but lies just outside its virial radius. [5] It is similar in structure and composition to the Small Magellanic Cloud . It is about 7,000 light-years in diameter.
Nearest galaxy to the Milky Way Sagittarius Dwarf Spheroidal Galaxy: 1994 0.070 Mly The closest, undisputed galaxy. The disputed dwarf galaxy Canis Major Overdensity is even closer at 25,000 light-years.

The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 ...
The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
