Ross 248, also called HH Andromedae or Gliese 905, is a small star located approximately 10.30 light-years (3.16 parsecs) from Earth in the northern constellation of Andromeda. Despite its proximity to the Earth, this star is too dim to be seen with the naked eye. Ross 248 was first catalogued by Frank Elmore Ross in 1926 with his second list of proper motion stars.
This star has about 12% of the Sun's mass and 16% of the Sun's radius, but only 0.2% of the Sun's luminosity. It has a stellar classification of M5.5Ve, which indicates it is a type of main sequence star known as a red dwarf. This is a flare star that occasionally increases in luminosity. With high probability, there appears to be a long-term cycle of variability with a period of 4.20 years. This variability causes the star to range in visual magnitude from 12.23 to 12.34. In 1950, this became the first star to have a small variation in magnitude attributed to spots on its photosphere.
