He was speaking at the 50th annual meeting of the American Astronomical Society Division for Planetary Sciences in Knoxville, Tennessee. > Kareta led an international team of researchers who investigated the odd asteroid, which sometimes behaves like a comet by releasing a dusty tail when it passes close to the sun, earning it the nickname the "rock comet." He says they found it to be even more enigmatic than expected.
