Michael E. Brown

Michael E. Brown, born on June 5, 1965, is a prominent American astronomer renowned for his groundbreaking contributions to planetary astronomy. Since 2003, he has held the esteemed position of professor at the California Institute of Technology (Caltech), where his research has significantly advanced our understanding of the solar system.

Brown's team has been instrumental in the discovery of numerous trans-Neptunian objects (TNOs), including the dwarf planet Eris. This discovery sparked a pivotal debate regarding the definition of a planet, as Eris was initially believed to be larger than Pluto, challenging the status of the latter.

Often referred to as the man who 'killed Pluto,' Brown's work has played a crucial role in Pluto's reclassification as a dwarf planet. His influential book, 'How I Killed Pluto and Why It Had It Coming,' published in two thousand ten, delves into the implications of his discoveries and the ensuing controversy.

In recognition of his significant contributions to astronomy, Brown was awarded the Kavli Prize in two thousand twelve, sharing this honor with Jane Luu and David C. Jewitt. This accolade was bestowed for their collective efforts in discovering and characterizing the Kuiper belt and its largest members, marking a major advancement in our understanding of the history of our planetary system.
