| Suggested name | Thea Ge |
| Planet type | Small cold gas planet |
| As seen relative to the fixed stars, it rotates on its axis exactly four times for every five revolutions it makes around HD 28109.
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 170°K (-103°C) at night to 1155°K (882°C) during the day across the equatorial regions.
The volume of water detected has been estimated to be equivalent to the volume of water in Earth's oceans. |
