WASP-69, also named Wouri, is a K-type main-sequence star 164 light-years (50 parsecs) away from Earth.
The data regarding starspot activity of WASP-69 are inconclusive, but spot coverage of the photosphere may be very high.
[2] Its equilibrium temperature is 886 K,[11] but the measured terminator temperature is significantly higher by at least 200 K.[7] The planet is losing mass at a moderate rate of 0.5 ME per billion years, not producing a visible cometary tail,[11] although it was detected in 2024 and measured to be at least 7 times its own radius.
[12] The planetary atmosphere is extremely hazy and contains a partial cloud deck with cloud tops rising to a pressure of 100 Pa. Its composition is mostly hydrogen and helium, and sodium was also detected in low concentration.
[14] By 2021, the presence of hazes in atmosphere of WASP-69b was confirmed, along with a solar or super-solar water abundance.
