7553 Buie           Discovered 1981 Mar. 30 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in honor of Marc W. Buie (b. 1958), an astronomer at Lowell Observatory, who has made many important contributions to planetary astronomy. These include the identification of water ice on Pluto's satellite Charon, constraints on the albedo and frost distribution on Pluto and Charon and improvements in our knowledge of Charon's orbit. Buie is also a codiscoverer of several transneptunian objects and has developed a wide variety of astronomical software used at Lowell Observatory and elsewhere. Citation provided by J. R. Spencer at the request of the discoverer.
