New Planet Is Largest Discovered That Orbits Two Suns
- _nalply 10y agoIf that planet hosts a large moon live might have evolved on it («within the so-called habitable zone – the range of distances from a star where liquid water might pool on the surface of an orbiting planet»). Compared to the Earth it would be a strange world. First there are two suns in the sky, both smaller than Sol and near to each other. Perhaps two thumbs held at an arm's distance. Then there is the big Jupiter-like planet. On this world there is no normal day-night rhythm. The moon most probably would be tidally locked to the planet. And the orbit around the binary is just above three years. Perhaps there are no spectacular sky scenes, however. A three-year «day» is very hard on the climate. For live to evolve it would have needed a permanent thick cloud cover like on Venus. Aliens living in that dark world would have no eyes. We could try to listen for a message from there. The star is located in the Cygnus constellation and quick googling gives distances between 170 and 1500 light years.
