Delofmontos

Delofmontos is a rather new world of the Estrehanosian system which, despite being young, has had a rather interesting past, scientists hypothesize that this world is older than one would expect (1-1.5 billion years old is its age), the reason it has so much magma is due to various factors. 1 an unstable core, scientists hypothesize that this world has a rather unstable core which is the reason for its violent expulsions of subsurface magma, we arent entirely sure why it has an unstable core however 1 theory suggests that it is because of the impact that a collision early in its life had.
2 the collision, it has rather thick and untidy rings with a rather different composition as well as odd geology, we do theorise that this is due to a collison from a world approximately 1 third the size of fordius but with the mass of 1.209 fordius's which explains the dense materials. Because ofthe time the collision had ocurred (at this time Delofmontos was in a cooldwnr was one of Xeloxonoxs moons is,) the weak and thin crust was cracked open in some areas which had a ripple effect where the force of the impact spread across it which opened up much weaker and lower elevation crust regions.
