WASP-69, also named Wouri, is a K-type main-sequence star 164 light-years (50 parsecs) away from Earth. 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, 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.
Multiplicity surveys did not detect any stellar companions to WASP-69 as of 2020.
