Astronomers have found a new planet, and it's the closet planet to our solar system. But don't get your hopes on going to visit there. It would take 40,000 years to get there and once you arrive, you'll find the planet is mostly lava. And it's much closer to its star than Mercury is to our sun. Its quick orbits on that short track take just 3.2 Earth days to make a year.
