![]() ![]() The team's numerical models suggest that the average surface temperatures would not be too different, with perhaps a 5° Celsius variation, but that the land-to-ocean distribution would affect the planets' climates. It is tempting to assume that a second Earth would be just like ours, but our modeling results suggest that this is not likely to be the case," said Prof Spohn, Executive Director of the International Space Science Institute in Bern, Switzerland. "We Earthlings enjoy the balance between land areas and oceans on our home planet. Barely 1% of the outcomes had an Earth-like distribution of land and water. ![]() Results from their models suggest that planets have approximately an 80% probability of being mostly covered by land, with 20% likely to be mainly oceanic worlds. ![]() Tilman Spohn and Dennis Höning studied how the evolution and cycles of continents and water could shape the development of terrestrial exoplanets. ![]()
