| Suggested name | Yaupo |
| Planet type | Hot planet |
| It is a hot planet planet with a mass one-thousandth that of KOI-4644, but two-and-a-half times that of all the other planets in its solar system combined.
The smooth Borealis basin in the northern hemisphere covers 35 percent of the planet and may be a giant impact feature. |
