WASP-80 - Wikipedia
WASP-80 is a K-type main-sequence star about 162 light-years away from Earth. The star's age is much younger than the Sun's at 1.352 ± 0.222 billion years. [ 7 ] WASP-80 could be similar to the Sun in concentration of heavy elements, although this measurement is highly uncertain.

[1303.0254] WASP-80b: a gas giant transiting a cool dwarf
2013年3月1日 · We report the discovery of a planet transiting the star WASP-80 (1SWASP J201240.26-020838.2; 2MASS J20124017-0208391; TYC 5165-481-1; BPM 80815; V=11.9, K=8.4). Our analysis shows this is a 0.55 +/- 0.04 Mjup, 0.95 +/- 0.03 Rjup gas giant on a circular 3.07 day orbit around a star with a spectral type between K7V and M0V.
