Clyde William Tombaugh (February 4, 1906 – January 17, 1997) was an American astronomer. Tombaugh is best known for discovering the dwarf planet Pluto in 1930, but also discovered many asteroids, and called for serious scientific research of unidentified flying objects.
Brett J. Gladman (born April 19, 1966) is a Canadian astronomer and a full professor at the University of British Columbia's Department of Physics and Astronomy, in Vancouver, British Columbia. He holds the Canada Research Chair in Planetary Astronomy. Gladman is best known for his work in dynamical astronomy in the Solar System.
Chadwick A. "Chad" Trujillo (born 22 November 1973), is an astronomer and the co-discoverer of the dwarf planet Eris. Trujillo works with computer software and has examined the orbits of the numerous trans-Neptunian objects (TNOs), which is the outer area of the solar system that he specialized in. In late August 2005, it was announced that Trujillo, along with Michael E. Brown and David L. Rabinowitz, had discovered Eris. This was the first TNO known to be larger than the planet Pluto.
Michael E. Brown (born June 5, 1965) has been a professor of planetary astronomy at the California Institute of Technology (Caltech) since 2003. He was previously an associate professor at Caltech from 2002–2003 and an assistant professor at Caltech from 1997–2002.
James Walter Christy (born 1938) is an American astronomer. Working at the United States Naval Observatory, on June 22, 1978 he discovered that Pluto had a moon, which he named Charon shortly afterwards. The name remained unofficial until its adoption by the IAU in 1986. The discovery was made by carefully examining an enlargement of a photographic plate of Pluto and noticing it had a very slight bulge on one side.
Robert S. McMillan is an astronomer at the University of Arizona, and heads the Spacewatch project, which studies minor planets. He has made various discoveries, including notably 20000 Varuna. On October 19, 2008 he discovered a short-periodic comet 208P/McMillan. In 1977 McMillan received his Ph.D. from the University of Texas at Austin.
Scott S. Sheppard is an astronomer in the Department of Terrestrial Magnetism at the Carnegie Institution for Science. Starting as a graduate student at the Institute for Astronomy at the University of Hawaii, he was credited with the discovery of many small moons of Jupiter, Saturn, Uranus and Neptune. He has also discovered the second known Neptune Trojan, 2004 UP10 as well as several Kuiper Belt Objects, Centaurs, and Near Earth Asteroids.
David C. Jewitt is a Professor of astronomy formerly at the University of Hawaii Institute for Astronomy, now at UCLA. He was born in 1958 in England, and is a 1979 graduate of the University of London. Jewitt received an M. Sc. and a Ph.D. in astronomy at the California Institute of Technology in 1980 and 1983, respectively. His research interests include the trans-Neptunian Solar System, Solar System formation and the physical properties of comets.
J-John Kavelaars, better known as JJ Kavelaars, is a Canadian astronomer who was part of a team that discovered several moons of Jupiter, Saturn, Uranus, and Neptune. Dr. Kavelaars is a graduate of the Glencoe District High School in Glencoe, Ontario, the University of Guelph, and Queen's University, Kingston, Ontario. He is currently an astronomer at the Dominion Astrophysical Observatory in Victoria, B.C.
Marc W. Buie is an astronomer at Lowell Observatory in Flagstaff, Arizona. He grew up in Baton Rouge, Louisiana and went on to get a B.S. in Physics from Louisiana State University in 1980. After that he switched fields and earned his Ph.D. in Planetary Science from the University of Arizona in 1984. Dr. Buie was a post-doctoral fellow at the University of Hawaii from 1985 to 1988.
Jun Chen is a Chinese American astronomer. She obtained her BS at Beijing University in 1990, and obtained her Ph.D. from the University of Hawaii in 1997. Working together with David Jewitt and Jane Luu and other astronomers, she has co-discovered a number of Kuiper belt objects. She is currently working as a software developer in private industry.
Audrey C. Delsanti (born 27 August 1976) is a French astronomer who co-discovered (40314) 1999 KR16 in 1999 whilst at La Silla Observatory in Chile. The Minor Planet Center erroneously lists her as "A. Dalsanti". In 2004 she was awarded a NASA Postdoctoral Fellowship in astrobiology at the Institute for Astronomy of the University of Hawaii in Honolulu.
S. Alan Stern (born 22 November 1957, New Orleans, Louisiana) is an American planetary scientist. Stern has several degrees including a Bachelor's degrees in physics & astronomy, Master's degrees in aerospace engineering and planetary atmospheres form the University of Texas, Austin), and a Doctorate in astrophysics and planetary science from the University of Colorado, Boulder.
Phillip D. Nicholson is a Professor of Astronomy at Cornell University in the Astronomy department specialising in Planetary Sciences. He was part of the team led by Brett J. Gladman that discovered several moons of Uranus and Saturn. He has been editor-in-chief of the journal Icarus since 1998.
