This is exciting news for Planet-Hunters. I just got an email from Zooniverse describing 28 new planets added to the list of discovered planets by Kepler's K2 mission. These new discoveries have been confirmed by scientists who review and evaluate the work by us (Planet-Hunters) who search for transits among the thousands of light curves detected by the Kepler Space telescope.
There are 9 planets in this list that are rocky (like Earth) with a radius less than twice the size of Earth. None have been identified within the habitable zones around their stars but some are very close and could harbour life.
Here is a detailed plot of the planets showing their size relative to Earth, their orbital periods around their host star, the heat intensity of the host star,
The new planet discoveries range in size from about 2/3 the radius of Earth to twice radius of Neptune. Below is the scientific footnote produced from the data.
Congrats to All Planet Hunters!
