Even though Pluto orbits at an average distance of 5.9 billion kilometers (3.7 billion miles) from the Sun. A new study suggests that Pluto may have maintained an underground ocean since early on in its life, potentially enhancing its chances of hosting life.  Scientists have long believed that Pluto started as an icy sphere when it developed in the Kuiper Belt, home to cold, dark objects on the edge of our solar system. There have been a lot of assumptions about the pluto, but if the findings are verified, other large objects in the Kuiper belt likely began hot, possibly harboring oceans billions of years ago.
