    Bumper car-like interactions at the edges of our solar system – and not a mysterious ninth planet – may explain the dynamics of strange bodies called “detached objects,” according to a new study. CU Boulder Assistant Professor Ann-Marie Madigan and a team of researchers have offered up a new theory for the existence of planetary oddities like Sedna. This minor planet orbits Earth’s sun at a distance of 8 billion miles but appears separated from the rest of the solar system.
     
    One theory for its unusual dynamics is that an as-of-yet-unseen ninth planet beyond Neptune may have disturbed the orbits of Sedna and other detached objects...

    It might be lingering on the icy outer edges of our solar system, stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side. It is a possible “Planet Nine” – a world perhaps 10 times the mass of Earth and 20 times farther from the sun than Neptune. The signs so far are indirect, mainly its gravitational footprints, but that adds up to a compelling case nonetheless. One of its most dedicated trackers, in fact, says it is now harder to imagine our solar system without a Planet Nine than with one.

    “There are now five different lines of observati...

    Curious Tilt of the Sun traced to Undiscovered Planet

    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. The large and distant planet may be adding a wobble to the solar system, giving the appearance that the Sun is tilted slightly...

    The solar system could be thrown into disaster when the sun dies if the mysterious ‘Planet Nine’ exists, according to research from the University of Warwick. Dr Dimitri Veras in the Department of Physics has discovered that the presence of Planet Nine – the hypothetical planet which may exist in the outer Solar System – could cause the elimination of at least one of the giant planets after the sun dies, hurling them out into interstellar space through a sort of ‘pinball’ effect...
