If a planet is there, it''s extremely distant and will stay that way (with no chance – in case you''re wondering – of ever colliding with Earth, or bringing "days of darkness"). It is a possible Planet Nine, a world perhaps 10 times the

Is there a Planet 9 on the outskirts of our Solar System?

New evidence strongly suggests the existence of a Planet 9 on the outskirts of our solar system. Image via Solen Feyissa/ Unsplash. The case is growing that a Neptune-sized planet – Planet 9 – hides deep in the outskirts of our solar system.

Planet 9 may be closer and easier to find than thought—if it exists

A new study''s "treasure map" suggests that a planet several times more massive than Earth could be hiding in our solar system, camouflaged by the bright strip of stars that make up the Milky Way.

Does planet Nine have a name?

Planet Nine does not have an official name and will not receive one unless its existence is confirmed via imaging. Only two planets, Uranus and Neptune, have been discovered in the Solar System during recorded history. [ 185 ] However, many minor planets, including dwarf planets such as Pluto, asteroids, and comets have been discovered and named.

Hypothetical Planet X

It could also make our solar system seem a little more "normal." Surveys of planets around other stars in our galaxy have found the most common types to be "super Earths" and their cousins — bigger than Earth, but smaller than Neptune. Yet none of this kind exist in our solar system. Planet Nine would help fill that gap.

Caltech Researchers Find Evidence of a Real Ninth Planet

It''s a pretty substantial chunk of our solar system that''s still out there to be found, which is pretty exciting." Brown notes that the putative ninth planet—at 5,000 times the mass of Pluto—is sufficiently large that there should be no debate about whether it is a true planet. Unlike the class of smaller objects now known as dwarf planets

Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU). These ETNOs tend to make their closest approaches
