HD 10307 (aka HR 483 A) is a star similar to the sun in mass, temperature and metal content, situated about 41 light-years from Earth in the constellation Andromeda. Its companion, HR 483 B, is a little-studied red dwarf.

HD 10307 was identified in September 2003 by astrobiologist Margaret Turnbull from the University of Arizona in Tucson as one of the most promising nearby candidates for hosting life based on her analysis of the HabCat list of stars.

System

HR 483 is a binary star located 41.2 ly away, in Andromeda. The pair orbit one another elliptically (e=0.43), approaching as close as 4.2 AU and receding to 10.5 AU, with a period of just under twenty years. Due to the high margins of error on the mass estimates for the two stars, these orbital parameters are approximate.

HD 10307, the larger component, is a main sequence, yellow, sun-like star, only slightly brighter, hotter, and larger than the Sun. HR 483 B, the smaller component, appears to be a red dwarf, with as little as thirty percent the mass of the sun.

Possibility of planets and life

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.

METI message to HD 10307

There was a METI message sent to HD 10307. It was transmitted from Eurasia's largest radar, 70-meter Eupatoria Planetary Radar. The message was named Cosmic Call 2, it was sent on July 6, 2003, and it will arrive at HD 10307 in September 2044.^[3]
