Video: Life on an Eyeball Planet? It’s Possible
By: SciShow Space
Eyeball planets are a nickname for planets that are tidally locked to their parent star., meaning the same side always faces the star. This name comes from the way the side facing the star would be a baked desert, the side facing away from the star would be a frozen wasteland, and there could be concentric circles of in between zones.
An example of a tidally locked celestial body is our own Moon.
This concept is pretty inhospitable to life, however it’s possible that a Eyeball planet orbiting a Red Dwarf, with a strong magnetic field, in the habitable zone, and with water and an atmosphere, could support life with temperatures between 50 and -50 celcius.
For these planets, life could exist in the area between the two sides. However, it would need to be able to deal with very little light, and very strong winds. Also, there would be no day/night cycle, something on which almost all life on Earth has some kind of reliance.
