| Suggested name | Ketar |
| Planet type | Hot planet |
| Ketar 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. Ketar is orbiting K2-88 every 4.6 Earth days.
It is named after the deity Ketar, the spirit of nature.
At this time it may appear as a bright star-like object, but is often far more difficult to observe than Steapus El.
Two spacecraft have visited Ketar: Daedalus 6 flew by 24 years ago; and Messenger, launched 17 years ago, orbited Ketar over 125 times in four years before exhausting its reactor and crashing into the planet's surface 6 years later.
The atmospheric pressure at the planet's surface is 60 bar, or roughly the pressure found 1440 m under the oceans of Earth.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
Liquid water cannot exist on the surface of Ketar due to low atmospheric pressure, which is less than 3 percent of Earth's, except at the lowest elevations for short periods. |
