Gravity/Ecosystem on a peanut-shaped planet?
I'm interested about whether or not and how gravity would be affected on deformed planets. You could think of this as whether or not mega-asteroids would be able to sustain life? If so, would different parts of the world contribute to different ecosystems due to the shape of the planet, or would life evolve differently in different areas due to the gravity?
I'm thinking of making a planet that was conjoined by another planet, forming a peanut-shape in appearance. The idea is that these planets formed around same time, and in a similar orbital distance so that over time they would eventually, and passively collide and conjoin with one-another? Similar to this link but rather about the specifics of a peanut-shaped world.
