Last year, the existence of an unknown planet in our Solar system was announced.

An unknown, unseen "planetary mass object" may lurk in the outer reaches of our solar system

The Australian National University (ANU) is launching a search for a new planet in our solar system, inviting anyone around the world with access to the Internet to help make the historic discovery.

In the year 2000 the first of a new class of distant solar system objects was discovered, orbiting the Sun at a distance greater than that of Neptune: the "extreme trans Neptunian objects (ETNOs).

Is Planet Nine Tilting The Sun?

Planet Nine, the undiscovered planet at the edge of the solar system that was predicted by the work of Caltech's Konstantin Batygin and Mike Brown in January 2016, appears to be responsible for the unusual tilt of the Sun, according to a new study.

In the race to discover a proposed ninth planet in our Solar System, Carnegie's Scott Sheppard and Chadwick Trujillo of Northern Arizona University have observed several never-before-seen objects at extreme distances from the Sun in our Solar System.

In the race towards the discovery of a ninth planet in our solar system, scientists from around the world strive to calculate its orbit using the tracks left by the small bodies that move well beyond Neptune.

Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit 10 times farther from our Sun than Pluto. Since then theorists have puzzled over how this planet could end up in such a distant orbit.
