Found Year: 2014
Dr. Scott Sheppard is the one who found it.
Location: The Solar System’s outer reaches
A person who was alive while Pluto was still regarded as a planet will not find it implausible in the slightest that there could be a ninth planet. But there is one key distinction between Planet Nine and Planet Nine, which will aid in understanding Pluto, the ninth planet.

Although Planet Nine cannot be proven to exist, there is evidence that worlds on the outer edge of the Milky Way share orbital characteristics. Pluto, on the other hand, has strong evidence supporting its existence. According to astronomer Dr. Scott Sheppard’s hypothesis, this is the outcome of the presence of a planet that is at least ten times larger than Earth and would take around 10,000 years to complete one solar orbit.
