2598 Merlin, provisional designation Template:Mp, is a carbonaceous Dorian asteroid from the central regions of the asteroid belt, approximately 16 kilometers in diameter. It was discovered on 7 September 1980, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona, United States.<ref name="MPC-Merlin" /> The asteroid was named after the legendary wizard Merlin in Arthurian legend.<ref name="springer" />

Classification and orbitEdit

Merlin is a member of the Dora family (Template:Small), a well-established central asteroid family of more than 1,200 carbonaceous asteroids. The family's namesake is 668 Dora. It is alternatively known as the "Zhongolovich family", named after its presumably largest member 1734 Zhongolovich. The Dora family may also contain a subfamily.<ref name="Broz-2013" /><ref name="Nesvorny-2014" />Template:Rp

Merlin orbits the Sun in the central main-belt at a distance of 2.2–3.4 AU once every 4 years and 8 months (1,694 days). Its orbit has an eccentricity of 0.22 and an inclination of 8° with respect to the ecliptic.<ref name="jpldata" /> In Nombember 1948, the asteroid was first identified Template:Mp at Uccle Observatory, where the body's observation arc begins 32 years prior to its official discovery observation at Anderson Mesa.<ref name="MPC-Merlin" />

Physical characteristicsEdit

In the SMASS classification, Merlin a Ch-type asteroid, a hydrated subtype of the broader carbonaceous C-complex.<ref name="jpldata" />

According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Merlin measures 15.694 kilometers in diameter and its surface has an albedo of 0.049.<ref name="Masiero-2011" />

LightcurvesEdit

As of 2017, no rotational lightcurve of Merlin has been obtained from photometric observations. The body's rotation period and shape remain unknown.<ref name="jpldata" /><ref name="lcdb" />

NamingEdit

This minor planet was named after the sage and sorcerer Merlin, featured mentor of King Arthur in Arthurian legend and medieval Welsh poetry. His magic enabled Arthur to pull Excalibur from the rock and become the rightwise king born of all England. The name was suggested by F. Pilcher.<ref name="springer" /> The approved naming citation was published by the Minor Planet Center on 4 August 1982 (Template:Small).<ref name="MPC-Circulars-Archive" />

NotesEdit

There is a book titled Merlin's Tour of the Universe, in which a fictitious character, called Merlin, answers all curious questions a layman would have about astronomy and the Solar System. In the book, Merlin's favorite asteroid is Merlin 2598.
