Initially, we thought there were nine planets in our solar system, but scientists agreed that Pluto is too small to be classified as a planet. Now a group of researchers have found another planet similar to Earth’s size to take its place.

Basically, if you believe that Pluto may still be called a planet instead of a dwarf planet, a new discovery made by a group of scientists at the California Institute of Technology can be interpreted as the tenth planet.

The big discovery was made somewhere near Pluto, and it seems to meet all requirements to be perceived as a planet. Moreover, it could be part of our solar system. “It could be” is the best word association because they’ve actually never seen it until now, and they assume it’s there because of a significant group of stars, about six, which orbits in an elliptic shape, inclined at an angle almost identical. Therefore, this phenomenon cannot occur unless a planet is placed among them to define their orbit.

Similar in size to our planet, the new discovery currently does not have a name and it will not until it will be seen directly.

“We don’t know exactly where it is, or else we’d just point the telescope at it tomorrow and it would be right there. But the sky is really big and this thing might be pretty faint, depending on how far out it is.” said Dr. Michael E. Brown, one of those responsible for the discovery.
