Dr. Rajesh Koothrappali is definitely a faculty and astrophysicist user in Caltech’s Physics Department. He had been the main united team to develop the latest Horizons room probe to get information concerning the Pluto system and past. For their finding of a planetary item beyond the Kuiper gear, 2008 NQ17 ( that he calls «Planet Bollywood»), he could be a part of People mag’s «30 Under 30 to Watch», giving him some type of celebrity status and a more substantial workplace for their work.
