While some astronomers remain unconvinced that such a plant exists, this new work isn’t the first to posit the existence of a ninth planet in our cosmic community.
Prior research has led to similar theories of an extra planet in the far reaches of our solar system, with Lykawka and Ito indicating a much more massive body than previously proposed, and at a much shorter distance from where we sit.If their calculations serve them correctly, Planet Nine would have a mass that is about 1.5 to 3 times that of Earth, at 500 times the distance between our home and the Sun.
Caltech researchers in 2014 were reportedly the first to come up with a firm theory on Planet Nine after observing disturbances in space objects just beyond Neptune, also known as trans-Neptunian objects . Separate research in 2020 hypothesized that a Planet Nine may have been positioned much more centrally within our system before Jupiter’s inception whizzed it off into the far reaches.flanked by 20 “hot” moonsSome may remember that Pluto was once considered our solar system’s ninth planet until it was demoted to dwarf planet in 2006, when scientists began to realize how many planetary bodies exist much like it — with the likes of other TNOs.
