This flat planet you've discovered is the third planet in its star system. It was discovered with the Kepler telescope.
The planet is about the size of Earth, and is thought to be rocky and flat. It has a diameter of about 12,700 kilometers. The planet is located in the habitable zone of its star, which means that it could potentially support life.
The atmosphere has not been studied in detail, but it is thought to be similar to Earth's. The planet receives about the same amount of sunlight as Earth does, and has a year that lasts about 365 days and it's named after the telescope that found it.
