'''3288 Seleucus''', provisional designation {{mp|1982 DV}}, is a rare-type stony [[asteroid]], classified as [[near-Earth object]] of the [[Amor asteroid|Amor]] group of asteroids, approximately 2.5 kilometers in diameter. It was discovered on 28 February 1982, by German astronomer [[Hans-Emil Schuster]] at [[European Southern Observatory|ESO]]'s [[La Silla Observatory]] site in northern Chile.<ref name="MPC-Seleucus" /> It was named after the Hellenistic general and Seleucid ruler [[Seleucus I Nicator]].<ref name="springer" />

=== Diameter and albedo ===

According to the survey carried out by NASA's [[Wide-field Infrared Survey Explorer]] with its subsequent [[NEOWISE]] mission, ''Seleucus'' measures 2.49 and 2.83 kilometers in diameter, and its surface has an [[astronomical albedo|albedo]] of 0.139 and 0.24, respectively.<ref name="Nugent-2015" /><ref name="Mainzer-2012" /> The ''Collaborative Asteroid Lightcurve Link'' adopts an albedo of 0.23 and a diameter of 2.2 kilometers, based on modeled data by Alan Harris.<ref name="Harris-1998a" /><ref name="lcdb" />

3288 Seleucus, provisional designation 1982 DV, is a rare-type stony asteroid, classified as near-Earth object of the Amor group of asteroids, approximately 2.5 kilometers in diameter. It was discovered on 28 February 1982, by German astronomer Hans-Emil Schuster at ESO's La Silla Observatory site in northern Chile.[3] It was named after the Hellenistic general and Seleucid ruler Seleucus I Nicator.[2]

Orbit

[edit]

Seleucus orbits the Sun in the inner main-belt at a distance of 1.1–3.0 AU once every 2 years and 11 months (1,059 days). Its orbit has an eccentricity of 0.46 and an inclination of 6° with respect to the ecliptic.[1] Seleucus has an Earth minimum orbital intersection distance of 0.1029 AU (15,400,000 km), which corresponds to 40.1 lunar distances.[1] As no precoveries were taken, and no prior identifications were made, the body's observation arc begins with its official discovery observation at La Silla.[3]

Physical parameters

[edit]

Spectral type

[edit]

On the Tholen and SMASS taxonomic scheme, Seleucus is classified as a featureless S-type and rare K-type asteroid, respectively.[1]

Rotation period

[edit]

It has a relatively long rotation period of 75 hours with a brightness variation of 1.0 magnitude, indicative of a non-spheroidal shape (U=3/3).[8][9] While most minor planets have spin rate between 2 and 20 hours, Seleucus still rotates faster than a typical slow rotator, which have periods above 100 hours.

Diameter and albedo

[edit]

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Seleucus measures 2.49 and 2.83 kilometers in diameter, and its surface has an albedo of 0.139 and 0.24, respectively.[5][6] The Collaborative Asteroid Lightcurve Link adopts an albedo of 0.23 and a diameter of 2.2 kilometers, based on modeled data by Alan Harris.[4][10]

Naming

[edit]

This minor planet is named for Seleucus I Nicator, a general in the army of Alexander the Great, and, after the death of Alexander, founder and king of the Seleucid Empire.[2] The approved naming citation was published by the Minor Planet Center on 29 September 1985 (M.P.C. 10046).[11]
