Planet NineDate: 21 September 2021 Tags: Space
Scientists have found evidence for a distant giant planet and nicknamed it Planet Nine. It may have mass about 10 times of Earth.
After the degradation in status of Pluto as the ninth planet, scientists have been on the look for another planet in our solar system.
Pluto is classified as a dwarf planet due to its size and the fact that it resides within a zone of other similarly-sized objects.
Many studies have been carried on the characteristics of Planet Nine. Some researchers have even called it super-earth.
Some studies even say that it could in fact be a black hole. The study also found a trans-Neptunian object called 2015 BP519.
The object was found to have an unusual trajectory due to the strong effects of gravity influenced by Planet Nine.
Scientists managed to conduct computer simulations that indicated that it is difficult to make objects like BP519 in absence of Planet Nine. In presence of Planet Nine, such objects could be easily formed.
The lead scientist says that they have found the area to look for Planet Nine. He also says that Planet Nine has a mass of 6.2 (+2.2/-1.3) Earth masses.
It is assumed that Planet Nine formed in the vicinity of the Uranus and Neptune and later got closer to Jupiter or Saturn that pushed it into the outer reaches of our solar system.
Evidence of the existence
There are evidences to prove that there is indeed a Planet Nine. If they are wrong, it could also be a Black Hole.
The anomalous orbits of the trans-Neptunian objects could have been due to the existence of a primordial black hole.
