Gliese 514, also known as BD+11 2576 or HIP 65859, is an M-type main-sequence star, in the constellation Virgo 24.88 light-years away from the Solar System.
Gliese 514's metallicity Fe/H index is largely unknown, with median values from -0.4 to +0.18 reported in the literature. This discrepancy is due to peculiarities of the stellar spectrum of Gliese 514. The spectrum peculiarities also affect the accuracy of the star's temperature measurement, with reported values as low as 2901 K. The spectrum of Gliese 514 shows emission lines, but the star itself has a low starspot activity.
Multiplicity surveys did not detect any stellar companions as of 2020.
The Sun is currently calculated to be passing through the tidal tail of Gliese 514's Oort cloud. Thus, future interstellar objects passing through the Solar System may originate from Gliese 514.
