| Planet type | Terrestrial |
| Yqas is the largest and most crater filled planet in its solar system.
Yqas is the only habitable planet orbiting Lalande 21185 and one of the oldest in its solar system. When viewed from Aheq Ukir, Yqas can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. This terrestrial is named after the deity Yqas, the spirit of war.
Yqas's surface is a dry desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Optical ground-based telescopes are typically limited to resolving features about 150 kilometers across when Yqas is closest because of Aheq Ukir's atmosphere. |
