Orbital variations can trigger ‘snowball’ states in habitable zones around sunlike stars

An artist’s impression of Earth as a frigid "‘snowball" planet. New research from the University of Washington indicates that aspects of a planet's axial tilt or orbit could trigger such a snowball state, where oceans freeze and surface life is impossible.

Aspects of an otherwise Earthlike planet’s tilt and orbital dynamics can severely affect its potential habitability — even triggering abrupt “snowball states” where oceans freeze and surface life is impossible, according to new research from UW astronomers.

‘Chaotic Earths’: Some habitable exoplanets could experience wildly unpredictable climates

ChaoticResonancePlanets04

New research by UW 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.
