Hatshem

Hatshem is a planet that orbits the star Mapthys in the Triangulum Galaxy. It is the homeworld of the Djeri.

Characteristics
A garden world, Hatshem orbits 0.69AUs from a K0V-type star.

Size
The diameter of Hatshem is 12400km. It has 0.9 Earth masses and so a density of 0.977 times Earth's. Its surface gravity is thus 0.97gs.

Dynamics
Hatshem has regular seasons. Its revolution around Mapthys takes 276 Earth days and its days are 20.2 hours long. The planet's axial tilt is 15.93 degrees, giving it mild seasons.

Composition
The planet's crust is 45.1% oxygen, 24.7% silicon, 19.4% iron, 8.7% aluminium, 1.8% calcium, and the remainder other elements.

Surface
The surface of Hatshem is 73% water. It has no ice caps. The average global temperature of the planet is 21 degrees Celsius.

Atmosphere
Hatsgem's atmosphere is 74.6% nitrogen, 24.5% oxygen, 0.8% argon, and the remainder other gases. The pressure at surface level is 0.91 bars.

Satellites
The planet has one large moon. Dehak is 2,900km in diameter and orbits at 370,000km from the surface. It was this moon which stabilised the planet's tilt and braked its rotation to a 20.2 hour day. The moon itself is tidally locked to Hatshem.
