Identification of a 4.3 billion year old asteroid family and planetesimal population in the Inner Main Belt
Abstract
After performing a reassessment of the known dynamical asteroid families in the inner main belt, we report a newly discovered ancient asteroid family with an estimated age of 4.31.7 billion years. Additionally, we report the most comprehensive list of planetesimals, which are asteroids that survived since the planet forming days of the solar system.
