Speculoos-3b, 55 light years away, is only second planetary system to be found around an ultra-cool red dwarf
Astronomers have discovered a new Earth-sized planet orbiting a small, cool star that is expected to shine for 100 times longer than the sun.
The rocky world, called Speculoos-3b, is 55 light years from Earth and was detected as it passed in front of its host star, an ultra-cool red dwarf that is half as hot as the sun and 100 times less luminous.
The newly discovered world, described as “practically the same size as our planet”, swings around the red dwarf once every 17 hours, making a year on the planet shorter than a single Earth day.
But while the years are short on Speculoos-3b, the days and nights are never-ending. “We believe that the planet rotates synchronously, so that the same side, called the day side, always faces the star, just like the moon does for the Earth. On the other hand, the night side hand, would be locked in endless darkness,” said Michaël Gillon, an astronomer at the University of Liège in Belgium and lead author on the study.
hmmm
"The planet’s tight orbit means it is bombarded with radiation, receiving almost 16 times more energy per second than Earth.
“In such an environment, the presence of an atmosphere around the planet is highly unlikely,”"
Florida 2?
I was thinking the same and if realism is creeping in if we can cope with the 55 light year journey we likely can cope with the radiation and lack of atmosphere.
