WD 0145+234 is a white dwarf star approximately 95 ly (29 pc)[3] from Earth in the constellation of Aries that has been associated with studies suggesting that a very large exoasteroid near the star was substantially disrupted, resulting in a considerable amount of dust and debris around the star.[3][5] Studies seem to have captured, for the first time, an exoasteroid breakup around the actual time interval of the disruption event.[3][5]
