| Aspherical planets a possibility..?
Now that extrasolar planets are being detected...
I've read plenty of SF stories about weird and wonderful shapes for planets - we know that it's possible for gas giants to be less than perfect globes a la Saturn - but is it genuinely feasible for a rocky planet like the Earth (which itself is slightly oblate) to have genuinely striking assymmetry?
Gravitational theory would tend to dictate that such a form would tear itself apart, no..? |
