Kepler-80: The ‘alien solar system’ where one year is as long as a day on Earth

India TV News  

Astronomers have discovered a bizarre ‘alien’ solar system that has planets orbiting its star so tightly that one of them has a year as along as a day on planet Earth. Moreover, these planets orbit in extreme proximity to their stars – they have ‘years’ equivalent to one, three, four, seven and nine Earth days. The study, led by Mariah MacDonald and Darin Ragozzine of the Florida Institute of Technology, stated that the planets resemble Earth’s rocky composition and have similar masses – four to six times that of Earth. Another rare attribute of the Kepler-80 system is that its planets have ‘synchronised’ orbits – the outer four planets return to almost exactly the same configuration after every 27 days.

NASA discovers 85 Earth-like planets that could support life

Daily Mail  

Scientists have revealed a promising development in the search for alien life. Generally, if a planet is a similar distance from its star as Earth from the sun, scientists could reasonably suggest it's not too hot and not too cold – and therefore could be habitable. The scientists know this because the planets orbited their star just twice during a …
