WASP-69
Star in the constellation Aquarius / From Wikipedia, the free encyclopedia
WASP-69, also named Wouri, is a K-type main-sequence star 164 light-years (50 parsecs) away.[6] Its surface temperature is 4782±15 K. WASP-69 is slightly enriched in heavy elements compared to the Sun, with a metallicity Fe/H index of 0.10±0.01,[4] and is much younger than the Sun at 2 billion years. The data regarding starspot activity of WASP-69 are inconclusive, but spot coverage of the photosphere may be very high.[7]
