Using a collaboration of telescopes including TRAnsiting Planets and PlanetesImals Small Telescope–South, seven new exo-planets have been found. Yesterday I eluded to all of them in the Goldilocks zone, that is not true but THREE of them are and ALL of the planets are relatively Earth-sized!
The star TRAPPIST-1 is a dwarf star, TRAPPIST-1 is only estimated to be only eight percent (8%) of our Sun, so it’s really small.
You will notice these planets are collectively very close to their parent star and that means very fast orbital periods, ranging from just a-(Earth)day-and-a-half for the closest planet (b) to only about 20 days for the most distant planet (h). Since the parent star is smaller and cooler that means the Goldilocks zone is much different than our own is. Click the graphic above to be able to see the data.
