Mychurek is a rather hot super-earth.
This planet has a radius of around 12,000km, and a density of over 5.5g/cm^3. This gives it a gravity of approximately 3.25g.
Mychurek has a thick crust of silicate material and a small iron-titanium core. Most of the volume is mantle, made of silicate and ferrous magma. Its atmosphere is rather thin, made of mainly carbon dioxide and nitrogen, with a thickness of 0.075atm.
It has a slightly elliptical orbit, lasting 73 days, but not overlapping any other planets' orbits, and a day period of 38 hours. It has two asteroid satellites, Dzronek and Nejirski.
With a surface temperature of nearly 300 degrees centigrate, nothing much is to be seen on this planet but craters and mountains. It has a rocky, grey surface, littered with dust and gravel from high-velocity asteroid impacts due to the large acceleration caused by the gravity.
