Summarize this article for a 10 year old
The Baptistina family (FIN: 403) is an asteroid family of more than 2500 members that was probably produced by the breakup of an asteroid 170 km (110 mi) across 80 million years ago following an impact with a smaller body. The two largest presumed remnants of the parent asteroid are main-belt asteroids 298 Baptistina and 1696 Nurmela. The Baptistina family is part of the larger Flora clan.[1][2] It was briefly speculated that the Chicxulub impactor was part of the Baptistina family of asteroids, but this was disproven in 2011 using data from the Wide-field Infrared Survey Explorer (WISE).
The Baptistina family consists of darkly colored asteroids and meteoroids in similar orbits. Baptistina broke up into thousands of fragments about 80 million years ago.[3]
