| Suggested name | Zosu |
| Planet type | Hot planet |
| As seen relative to the fixed stars, it rotates on its axis exactly four times for every five revolutions it makes around K2-127.
Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 50°K (-223°C) at night to 455°K (182°C) during the day across the equatorial regions.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
The smooth Borealis basin in the northern hemisphere covers 13 percent of the planet and may be a giant impact feature.
