The Mystery Of The Self-Destructing Asteroid

A first observed instance of an asteroid breaking apart now has astronomers baffled, Reuters reported. The new images, captured throughout a period of several months by NASA’s Hubble Telescope, show an asteroid disintegrating and breaking into at least 10 pieces.
What’s puzzling scientists is what led the asteroid to disintegrate. Unlike most space rocks that break apart after a head-on collision, asteroid P/2013 R3 appears to have crumbled without an impetus.
So why did the asteroid suddenly break apart?
A team of researchers explained in a paper in the Astrophysical Journal Letters, published online March 6, that sunlight may be a factor in the asteroid’s disintegration. The researchers describe a “subtle effect” in which sun rays could have caused the asteroid to rotate slightly faster. As the space rock’s rate of rotation gradually increased, centrifugal force caused pieces of the asteroid to pull apart. Over time, an asteroid under this type of force would appear to disintegrate from the inside out.
