Didier Patrick Queloz (born February 23, 1966 ) is a Swiss astronomer . In 1995, together with Michel Mayor , he discovered the first extrasolar planet orbiting a sun-like star ( 51 Pegasi b ), for which both received the Nobel Prize in Physics in 2019 .
Didier Queloz graduated from the University of Geneva with a master's degree in physics in 1990 and received his PhD in astronomy there in 1995 ( Ph.D. ) with Michel Mayor . He has been Professor of Physics at the Cavendish Laboratory at Cambridge University and at the University of Geneva since 2013 .
The discovery of the extrasolar planet, together with Michel Mayor, is based on measurements of the radial velocity according to the Doppler effect , the first planet found had an orbital velocity of 4.2 days. On July 23, 2015, Queloz announced the first discovery of an Earth-like planet, Kepler-452b , to NASA . This was also referred to as "second earth" or "older cousin of the earth".
