Mercury
A quick art. Actually i was testing a half lava/half stone ground shader.
Mercury: The first planet of our solar system. It is 0.3 a.u. from the Sun.
Being so close to the central star of the system makes Mercury a hostile planet to life. 170º C during the day and -150º during the night, also, the atmosphere is inexistent. It is a rock, and although the lava here is actually an artistic license, it seems that actually, lava flowed from inside Mercury.
The monolith... Don't mind it, it seems it was just passing by... or something.
