Ross 248, also called HH Andromedae or Gliese 905, is a small star approximately 10.30 light-years (3.16 parsecs) [10] from Earth in the northern constellation of Andromeda. Despite its proximity it is too dim to be seen with the naked eye. [11]
In the constellation, the star is situated about halfway between the bright star Mirach to the southwest and the Andromeda Galaxy (M31) to the northeast. [11] The spectrum of this star matches a stellar classification of A5 V, [3] indicating that it is an A-type main sequence star. It has 2.2 times the mass of the Sun and three times the Sun's ...
