Our Sun started its life with a binary companion, new study suggests

A new theory published this week in the AAS' The Astrophysical Journal Letters suggests that our Sun may once have had a binary companion of similar mass. If confirmed, the presence of an early stellar companion increases the likelihood that the Oort cloud was...

Our star's companion is approaching the inner planets of the Solar System

There is no such thing as Planet 9 or Planet X. What actually exists is the companion of the Sun. It is a brown dwarf and its size is between 10 - 20 times that of the Earth. This brown dwarf is circling the Sun in a vast orbit which takes it 60 times further than...

New data about two distant asteroids give a clue to the possible “Planet Nine”

The dynamical properties of these asteroids, observed spectroscopically the first time using the Gran Telescopio CANARIAS, suggest a possible common origin and give a clue to the existence of a planet beyond Pluto, the so-called “Planet Nine”. In the...

Planet Nine tilts the Sun - Q and A with Caltech astronomers

The search for so-called Planet Nine - an 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 - has yielded another important realization. It appears to be responsible...

Planet Nine may have caused orbital tilts of all Solar System planets

Following a major discovery implying that a ninth planet may be orbiting our solar system, the scientists are investigating its possible impact on the tilted orbits observed for the other planets. All known planets of the Solar System have their orbits in almost the...

Planet 9 - the first exoplanet within our home solar system

The newest computer simulation, conducted by researchers from the Lund University in Sweden, suggests the so-called Planet 9 is most likely an exoplanet. If the discovery proves correct, it will make it the first exoplanet revealed inside our home solar system and,...

Planet Nine: Caltech researchers announce evidence of a giant new Solar System planet on a highly elongated orbit

Two Caltech researchers have announced today, January 20, 2016, they have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times...
