Gliese 754
Location of Gliese 754 in the constellation Telescopium
Gliese 754 is a dim star in the southern constellation of Telescopium. It has an apparent visual magnitude of 12.25,[2] which requires a telescope to view. The star is located at a distance of 19.3 light-years from the Sun based on parallax,[1] and it is drifting further away with a radial velocity of +7 km/s.[3] It is one of the hundred closest stars to the Solar System. Calculations of its orbit around the Milky Way showed that it is eccentric, and indicate that it might be a thick disk object.[8]
The stellar classification of Gliese 754 is M4V,[2] indicating that this is a small red dwarf star on the core hydrogen fusing main sequence. It has 17% of the mass of the Sun and 21% of the Sun's radius.[3] The star is fully convective and is a source of X-ray emission.[9] It is rotating slowly with a period of about 133 days.[3] The metallicity is sub-solar,[6] indicating it has a lower abundance of heavy elements compared to the Sun. It is radiating just 0.5%[5] of the luminosity of the Sun from its photosphere at an effective temperature of around 3,202 K.[6]
