What is its Name? Batygin and Brown nicknamed their predicted object “Planet Nine,” but the actual naming rights of an object go to the person who actually discovers it. The name used during previous hunts for the long suspected giant, undiscovered object beyond Neptune is “Planet X.”
When was Planet X founded?
The X means unknown. Planet X was first applied to Pluto before its discovery in 1930 (as the ninth planet) and then to Eris before it was discovered in 2005 (as the tenth planet). However, as of 2006, both former planets were reclassified as dwarf planets, resulting in only eight planets in the solar system.

Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
What is a white black hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Does Earth have a black hole?
It’s a wild idea that isn’t necessarily based in nonsense, but the data we’ve collected has thoroughly demonstrated that there isn’t a black hole at the center of the Earth. Here’s the story of how we scientifically know that the Earth’s interior is black hole-free.

The planet, one and a half times the mass of Jupiter, has a roughly circular orbit, like those of the sun’s family of planets.
Could we live on Eris?
The surface of Eris is extremely cold, so it seems unlikely that life could exist there.
