UDF 2457 is the Hubble Ultra Deep Field identifier for a red dwarf star calculated to be about from Earth with a very dim apparent magnitude of 25.
The Milky Way galaxy is about 100,000 light-years in diameter, and the Sun is about 25,000 light-years from the Galactic Center. The small common star UDF 2457 may be one of the farthest known stars inside the main body of the Milky Way. Globular clusters and stellar streams are located farther out in the galactic halo.
