| Sewonya'hido |
| Cold planet |
| It is a cold planet planet with a mass one-thousandth that of HD 74698, but two-and-a-half times that of all the other planets in its solar system combined. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to HD 74698, which reoccurs over the so-called synodic period approximately every 116 days. |
