Yattuk

Yattuk is the fourth moon of the planet Espa in the Odjoran system. Together with Azhban its the second of the major moons, its roughly 1460 km across, It has an angular diameter of 32 arcminutes and 8.82 arcseconds, thus it appears 1.037 times bigger than the size of earths moon from Espa's surface.

Surface
Yattuk has a similar appearance to earths moon being mostly grey and white but with a touch of pink, unlike earths moon however its been able to retain a faint atmosphere, allowing for a better resistance against asteroid impacts, albeit the surface is still abundant in impact craters there is visibly less of them than on Earth's Moon.

The surface of Yattuk is very salty, the lithosphere consists of 73% of various salts (those mainly being: NaCl (49%), Calcium carbonate (CaCO3) (12%) and Potassium iodide (KI) (8%). Yattu's atmosphere consists almost entirely out of Carbon dioxide, a composition very similar to Mars.

Orbit
The Orbit of Yattuk resonates in a 2:3 ratio with that of Azhban. Meaning that for every 2 orbits of Yattuk, Azhban completes 3 of its own. It's Tidally locked in its orbit meaning the same side of the moon is always facing Espa.
