A massive object four times the size of Jupiter could be lurking in the outer solar system.
The mystery object is thought to be responsible for sending comets out of the Oort cloud in our direction and could be a new planet that has remained undiscovered due to its distance and freezing temperature.
Most comets that fly into the inner solar system seem to come from the outer region of the Oort cloud - a region of icy dust and debris left over from the birth of the solar system. The cloud starts from a point about 93 billion miles from the Sun and stretches for around three light years and contains billions of comets, most of them small and hidden.
