HD 10307 (HR 483) is a

spectroscopic binary star in the constellation Andromeda. The primary is similar to the Sun in mass, temperature and metal content. situated about 42 light-years from Earth Its companion, HR 483 B, is a little-studied red dwarf
.

HD 10307 was identified in September 2003 by astrobiologist

HabCat list of stars.[11]

System

HD 10307 in optical light

HR 483 is a binary located 42.6 ly away, in Andromeda. The two stars orbit one another elliptically (e=0.44),[12] approaching as close as 4.2 AU and receding to 10.5 AU, with a period of just under twenty years.[6]

HD 10307 A, the larger component, is a

Maunder minimum analog.[13] HR 483 B, the smaller component, appears to be a red dwarf, with as little as thirty-eight percent the mass of the sun.[3] A debris disk has been detected in this system.[14]

The presence of a moderately close companion could disrupt the orbit of a hypothetical planet in HD 10307's habitable zone. However, the uncertainty of the orbital parameters makes it equally uncertain exactly where stable orbits would be in this system.[10]

METI message to HD 10307

There was a

Cosmic Call 2, it was sent on July 6, 2003, and it will arrive at HD 10307 in September 2044.[15]
