Template:Use dmy dates Script error: No such module "infobox".Script error: No such module "Check for unknown parameters". Template:Mp is a trans-Neptunian object and the tenth-most-distant known object in the Solar System since 2015[update]Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters".. Considered a detached object,[1][2] it orbits the Sun in a highly eccentric orbit every 3,305 years at an average distance of 222 astronomical units (AU).[3]
Description
Script error: No such module "Labelled list hatnote". Mike Brown's website lists it as a possible dwarf planet with a diameter of Script error: No such module "convert". based on an assumed albedo of 0.04 .[4] The albedo is expected to be low because the object has a blue (neutral) color.[4] However, if the albedo is higher, the object could easily be half that size.
Template:Mp and Sedna differ from scattered-disc objects in that they are not within the gravitational influence of the planet Neptune even at their perihelion distances (closest approaches to the Sun). It is something of a mystery as to how these objects came to be in their current, far-flung orbits. Several hypotheses have been put forward:
- They were pulled from their original positions by a passing star.[5][6]
- They were pulled from their original positions by a very distant, and as-yet-undiscovered (albeit unlikely), giant planet.[7]
- They were pulled from their original positions by an undiscovered companion star orbiting the Sun such as Nemesis.[7]
- They were captured from another planetary system during a close encounter early in the Sun's history.[5] According to Kenyon and Bromley, there is a 15% probability that a star like the Sun had an early close encounter and a 1% probability that outer planetary exchanges would have happened. Template:Mp is estimated to be 2–3 times more likely to be a captured planetary object than Sedna.[5]
Template:Mp is the first object discovered in the Solar System to have a semi-major axis exceeding 150 AU, a perihelion beyond Neptune, and an argument of perihelion of Script error: No such module "val"..[8] It is one of eleven objects known with a semi-major axis greater than 100 AU and perihelion beyond 42 AU.[9] It may be influenced by Planet Nine.[10]
