Aspects of an otherwise Earthlike planet鈥檚 tilt and orbital dynamics can severely affect its potential habitability 鈥 even triggering abrupt 鈥渟nowball states鈥 where oceans freeze and surface life is impossible, according to new research from 91探花astronomers.

New research by 91探花astronomer Rory Barnes and co-authors describes possible planetary systems where a gravitational nudge from one planet with just the right orbital configuration and tilt could have a mild to devastating effect on the orbit and climate of another, possibly habitable world.
