    It’s not in our solar system, guys. This planet is one of Kepler-139’s, it doesn’t transit its star as viewed from Earth so it had to be observed indirectly via its effects on the orbits of the planets on either side of its orbit. That being said, it IS in Kepler-139’s habitable zone with a year about 355 Earth days long.

  2. “35 times more massive” is somewhat misleading, because a planet slightly more than 3 times Earth’s diameter would be 35 times more massive.
