The Pegasus Dwarf Irregular Galaxy is about 3 million light years from us.
See related link for more information.
If you were thinking about the Andromeda Galaxy, that is only (!) 2.54 million light years from us.
Dwingeloo 1 galaxy is about 9 million light years from us. Dwingeloo 2 a satellite galaxy of D1 is about 10 million light years from us.
Two nearby galaxies are Andromeda galaxy and Triangulum galaxy. Andromeda galaxy is about 2.56 million light years away from us. Triangulum galaxy is about 3 million light years away from us.
The Andromeda galaxy is about 2.4 million light years away, meaning that light from it takes 2.4 million light years to reach us, so the light we see from it now was emitted 2.4 million years ago.
The Tadpole Galaxy is a disrupted barred spiral galaxy about 400 million light years from us.
At the current estimates, the Andromeda Galaxy is about 2.54 million light years from us, and getting closer every year. At that rate, it is expected to "merge" not "collide" in about 4.5 billion years.
I assume you mean M31, the Andromeda Galaxy. It is approximately 2.5 million light-years from us; that means that it takes light 2.5 million years to travel from there to here (or from here to there).
8 million years. A light-year is the distance light travels in a year.
The nearest galaxy to us is the Canis Major Dwarf about 0.025 million light years away.
The Sunflower Galaxy (M63, or NGC 5055) is a spiral galaxy in the constellation Cane.It is approximately 37 million light years from us.
The nearest galaxy to us is the Canis Major Dwarf about 0.025 million light years away.
The Andromeda Galaxy is the closest large galaxy to us and is approximately 2.5 million light years away! The Sagittarius Dwarf Elliptical Galaxy is the closest galaxy of any size that we know of. It's about 70,000 light years from Earth, or about 50,000 light years from the galactic center, and orbits the Milky Way.
Traveling to another galaxy at the speed of light would take an incredibly long time. The closest galaxy to us, the Andromeda galaxy, is about 2.5 million light-years away. This means it would take 2.5 million years to reach Andromeda at the speed of light.
