Habitabgchekill

Habitabgchekill is the semi-habitable planet of the Ruber Caliginosus system.
Apparently some kind of extremophile blue plant species has expanded to the whole planet, hence its blue color.
It would be habitable if it wasnt for its 263-day rotation... What caused it? Lets find out in:
==Formation==
The planet is approximately 4.5 billion years old, and those plants got to Habitabgchekill a few hundred million years ago.
The young Habitabgchekill had a massive colliion with a Mars-sized planet 4.308 billion years ago, reversing its rotation.
