Kethira, Planet

Kethira is the second planet in the Nolomar star system, it is further from its star, Nolomar, which is larger than Sol. Compared to Terra, Kethira has a smaller diameter, but its denser core gives it similar mass and gravity. The actual orbital period of Kethira around Nolomar is 360 days using Hârnic Tuzyn Reckoning, the calendar in most common use throughout western Lythia, the largest continent on Kethira. The actual orbital period of Kethira is 360.0011 days which has introduced an error of 15.5 hours of drift to the Tuzyn calendar since it originated 720 years ago. Astronomers have noted this difference but judge the error does not yet warrant any adjustment. Kethira rotates on its axis once every twenty four hours. Kethira has one moon Yael.

Yael (The Moon)

Kethira has one moon, called Yael, which orbits at an average distance of 214994 miles (346K km). Yael has a diameter of 2572 miles (4,140 km), slightly larger than Terra's moon Luna. Yael rotates once on its axis every 15 hours, and has a synodic period (time between full moons) of a few minutes under 30 days. Because the synodic period is almost exactly one-twelfth of the Kethiran year, moon phases occur on the same day each month.
