| Suggested name | Lean |
| Planet type | Warm gas giant |
| Lean is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Lean is orbiting WASP-132 every 7.1 Earth days.
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 88°K (-185°C), and has a complex, layered cloud structure with ethane thought to make up the lowest clouds, and argon the uppermost layer of clouds. It is named after the deity Lean, the god of prosperity.
Two spacecraft have visited Lean: Wayfinder 8 flew by 36 years ago; and Messenger, launched 23 years ago, orbited Lean over 90 times in four years before exhausting its reactor and crashing into the planet's surface 7 years later.
Lean's surface is a barren desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
As the closest planet to Tungr Rodes-lirr, Lean has been a prime target for early extra solar exploration.
Lean is the site of Titanic Mountain, the most active volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system. |
