The search for a possible ninth planet in our Solar System has intensified in recent months, with more astronomers as well as amateurs joining in the hunt. Previous studies have hinted at its existence, but actually finding it has remained an elusive task. Now, astronomers from The Australian National University (ANU) are investigating four unknown objects in the outer Solar System that could be viable candidates for the mystery planet.
The announcement of a possible large ninth planet in our Solar System way beyond Neptune last month caused a lot of excitement, needless to say. If confirmed, it may be similar to “super-Earth” type exoplanets which have been found to be plentiful around other stars, although none, that we knew of, around ours. At this point, however, it is still a well-presented theory. Now, there’s another possibility which has been offered to explain the weird orbits of some of the small Kuiper Belt objects – not a large planet, but rather a second Kuiper Belt consisting of many smaller objects instead.
