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]

Multiplicity surveys did not detect any stellar companions to WASP-69 as of 2020.^[8]

The designation WASP-69 indicates that this was the 69th star found to have a planet by the Wide Angle Search for Planets.

In August 2022, this planetary system was included among 20 systems to be named by the third NameExoWorlds project.^[9] The approved names, proposed by a team from Cameroon, were announced in June 2023. WASP-69 is named Wouri and its planet is named Makombé, after the Wouri and Makombé rivers.^[10]

In 2013, one planet, named WASP-69b,^[6] was discovered on a tight, circular orbit.^[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 M_E 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.^[7][13] The sodium may originate from volcanic moons, not from the planet itself.^[14]

By 2021, the presence of hazes in atmosphere of WASP-69b was confirmed, along with a solar or super-solar water abundance.^[15]
