Шаблон:Mp is a resonant trans-Neptunian object, approximately Шаблон:Convert in diameter, located in the outermost region of the Solar System. It was discovered by Slovak astronomer Tomáš Vorobjov from images taken on the night of 19 April 2012, at the Astronomical Research Institute Шаблон:Obscode in Illinois, United States. This minor planet was numbered (432949) by the Minor Planet Center on 4 April 2015 (Шаблон:Small). Шаблон:As of, it has not been named.

Шаблон:Mp is a resonant trans-Neptunian object in an uncommon 4:5 resonance with Neptune (DES: 5:4E). It orbits the Sun at a distance of 29.2–40.4 AU once every 205 years and 4 months (75,008 days; semi-major axis of 34.81 AU). Its orbit has an eccentricity of 0.16 and an inclination of 29° with respect to the ecliptic. It is currently 29.8 AU from the Sun.

Шаблон:As of, no rotational lightcurve of Шаблон:Mp has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown. JohnstonШаблон:'s Archive estimates a mean-diameter of Шаблон:Convert, using a standard magnitude-to-diameter conversion with an assumed albedo of 0.09. Astronomer Mike Brown gives a nearly identical estimates of Шаблон:Convert for the object's diameter with an albedo of 0.08 and an absolute magnitude of 6.3.
