'''Chadwick A. Trujillo''' (born November 22, 1973) is an American [[astronomer]], discoverer of [[minor planet]]s and the co-discoverer of [[Eris (dwarf planet)|Eris]], the most massive [[dwarf planet]] known in the [[Solar System]].<ref name="springer" /><ref name="MPC-Eris" />

Trujillo works with computer software and has examined the orbits of the numerous [[trans-Neptunian object]]s (TNOs), which is the outer area of the Solar System that he specialized in. Trujillo, along with [[Michael E. Brown|Michael Brown]] and [[David L. Rabinowitz|David Rabinowitz]], discovered [[Eris (dwarf planet)|Eris]] in 2003.<ref name="MPC-Eris" /> As a result of the discovery of the satellite [[Dysnomia (moon)|Dysnomia]], Eris was the first TNO known to be more massive than [[Pluto]].<ref name="Brown-2007"/>

==Career==
Trujillo attended [[Oak Park and River Forest High School]] in [[Oak Park, Illinois]]. He received his B.Sc. in [[physics]] from the [[Massachusetts Institute of Technology]] in 1995, and was a member of the Xi chapter of [[Tau Epsilon Phi]], and received his Ph.D. in astronomy from the [[University of Hawaiʻi]] in 2000.

Between 2000 and 2003 Trujillo was a postdoctoral scholar at [[California Institute of Technology|Caltech]]. In 2003, he started working as an astronomer at the [[Gemini Observatory]] in Hawaii.<ref name="Nupepa" />

In 2013 Trujillo became head of the Adaptive Optics/Telescope Department at the Gemini Observatory, and continued until 2016. As of 2016, Trujillo is assistant professor at the department of Astronomy and Planetary Science at [[Northern Arizona University]].<ref name="cv">{{cite web|url=https://profile.directory.nau.edu/person/cat382|title=Chad Trujillo CV}}</ref>

He studies the [[Kuiper belt]] and the [[outer Solar System]].

Trujillo is credited by the [[Minor Planet Center]] with the discovery and co-discovery of 54 numbered [[minor planet]]s between 1996 and 2013, including many [[trans-Neptunian object]]s (TNOs) from the [[Kuiper belt]] ''(see table)''.<ref name="MPC-Discoverers" /> The last major TNO, Eris, was at first considered by him, his team, [[NASA]], and many others to be the tenth planet,<ref name="Nupepa" /> but the [[International Astronomical Union]] assigned it to the new classificatory category of [[dwarf planet]].

The possible dwarf planets Trujillo discovered are:
*[[50000 Quaoar|Quaoar]], co-discovered with Brown
*[[90377 Sedna|Sedna]], co-discovered with Brown and Rabinowitz, possibly the first known inner [[Oort cloud]] object
*[[90482 Orcus|Orcus]], co-discovered with Brown and Rabinowitz
*[[Eris (dwarf planet)|Eris]], co-discovered  with Brown and Rabinowitz – the only known TNO more massive than Pluto<ref name="Brown-2007" />
*{{dp|Haumea}}, discovery also claimed by the [[Sierra Nevada Observatory]], Spain ''(also see [[José Luis Ortiz Moreno]])''.<ref name="MPC-Haumea" />
*{{dp|Makemake}}, co-discovered with Brown and Rabinowitz in 2005, one of the first 5 official dwarf planets.<ref name="MPC-Makemake" />
