Because it has the tightest orbit around a star ever seen, one thing researchers know for sure is that Kepler-78b’s days are numbered. The extreme gravitational pull from its star will draw it ever closer in, ripping the entire planet apart in about three billion years.

That is still quite a bit of time, i though this thing was either already pulled in or its going to happen sometime in the near future (1 million years maybe), definitely wasnt expecting to read, 3 billion years. Wont Earth itself be inhabitable in about 1 billion years?
