HD 180314 is a star with an orbiting substellar companion in the northern constellation of Lyra.
It is near the lower limit of visibility to the naked eye with an apparent visual magnitude of 6.61.
[2] The distance to this system is 401 light years based on parallax measurements, but it is drifting closer with a heliocentric radial velocity of −73.9 km/s.
[2] At the age of roughly 600 million years, it has exhausted the supply of hydrogen at its core and expanded away from the main sequence.
The star is radiating 44 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,997 K.[3] The star is orbited by one substellar companion, HD 180314 b,[4] an object with a minimum mass 22 times that of Jupiter and hence likely to be a brown dwarf.
