Title: The Extraordinary Multi-Tailed Main-Belt Comet P/2013 P5
Author: David Jewitt, Jessica Agarwal, Harold Weaver, Max Mutchler, Stephen Larson

Hubble Space Telescope observations of main-belt comet P/2013 P5 reveal an extraordinary system of six dust tails that distinguish this object from any other. Observations two weeks apart show dramatic morphological change in the tails while providing no evidence for secular fading of the object as a whole. Each tail is associated with a unique ejection date, revealing continued, episodic mass loss from the 0.24+/-0.04 km radius nucleus over the last five months. As an inner-belt asteroid and probable Flora family member, the object is likely to be highly metamorphosed and unlikely to contain ice. The protracted period of dust release appears inconsistent with an impact origin, but may be compatible with a body that is losing mass through a rotational instability. We suggest that P/2013 P5 has been accelerated to breakup speed by radiation torques.

NASA's Hubble Sees Asteroid Spouting Six Comet-Like Tails

Astronomers viewing our solar system's asteroid belt with NASA's Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust radiating from it like spokes on a wheel.
Unlike all other known asteroids, which appear simply as tiny points of light, this asteroid, designated P/2013 P5, resembles a rotating lawn sprinkler. Astronomers are puzzled over the asteroid's unusual appearance.

Preliminary orbital elements of the comet P/2013 P5 (PANSTARRS) indicate a perihelion passage on April 17, 2014 at a distance of 1.9 AU from the Sun, and an orbital period of 3.2 years.
