'''10415 Mali Lošinj''', provisional designation {{mp|1998 UT|15}}, is a dark background [[Astronomy:Asteroid|asteroid]] and very [[Astronomy:List of slow rotators (minor planets)|slow rotator]] from the outer region of the [[Astronomy:Asteroid belt|asteroid belt]], approximately 16 kilometers in diameter. It was discovered by Croatian astronomer [[Biography:Korado Korlević|Korado Korlević]] at Višnjan Observatory, Croatia, on 23 October 1998.<ref name="MPC-Mali Losinj" /> The asteroid was named after the Croatian town of Mali Lošinj.

== Orbit and classification ==

''Mali Lošinj'' orbits the Sun in the [[Astronomy:Kirkwood gap|outer]] main-belt at a distance of 2.9–3.1&nbsp;[[Astronomy:Astronomical unit|AU]] once every 5 years and 2 months (1,887 days). Its orbit has an [[Astronomy:Orbital eccentricity|eccentricity]] of 0.03 and an [[Astronomy:Orbital inclination|inclination]] of 14[[Degree (angle)|°]] with respect to the [[Astronomy:Ecliptic|ecliptic]].<ref name="jpldata" /> The first used [[Astronomy:Precovery|precovery]] was obtained at Goethe Link Observatory in 1962, extending the asteroid's [[Astronomy:Observation arc|observation arc]] by 36 years prior to its discovery. The first unused observations were made at Heidelberg Observatory in 1925.<ref name="MPC-Mali Losinj" />

== Physical characteristics ==

The asteroid has also been characterized as an [[Astronomy:X-type asteroid|X-type asteroid]] by [[Astronomy:Pan-STARRS|Pan-STARRS]] photometric survey.<ref name="lcdb" /><ref name="Veres-2015" />

=== Slow rotators ===

In September 2013, [[Astronomy:Photometry|photometric]] observations at the [[Astronomy:Palomar Transient Factory|Palomar Transient Factory]] in California gave a rotational [[Astronomy:Lightcurve|lightcurve]] that showed a [[Rotation period|period]] of {{val|240.5115}} hours with a brightness amplitude of 0.48 in [[Astronomy:Magnitude|magnitude]] ({{small|U=2}}).<ref name="Waszczak-2016" /> ''Mali Lošinj'' is a [[Astronomy:List of slow rotators (minor planets)|slow rotator]], as asteroids of this size usually rotate within hours once around its axis.

=== Diameter and albedo ===

According to the surveys carried out by NASA's [[Astronomy:Wide-field Infrared Survey Explorer|Wide-field Infrared Survey Explorer]] and its subsequent [[Astronomy:NEOWISE|NEOWISE]] mission, ''Mali Lošinj'' measures between 13.5 and 16.2 kilometers in diameter and its surface has an [[Astronomy:Astronomical albedo|albedo]] between 0.13 and 0.15.<ref name="Masiero-2011" /><ref name="WISE" /><ref name="Masiero-2012" /> The ''Collaborative Asteroid Lightcurve Link'' assumes a standard albedo for [[Astronomy:C-type asteroid|carbonaceous asteroids]] of 0.057 and calculates a somewhat larger diameter of 18.8 kilometers with an [[Astronomy:Absolute magnitude|absolute magnitude]] of 12.36.<ref name="lcdb" />

== Naming ==

This [[Astronomy:Minor planet|minor planet]] was named after the Croatian town of Mali Lošinj, located on the island of Lošinj, in the northern [[Place:Adriatic Sea|Adriatic Sea]]. The island and the town are well known for its nautical school and the ''Leo Brener Observatory''.<ref name="springer" /> The minor planet [[Astronomy:10645 Brač|10645 Brač]] is also named after a Croatian island in the Adriatic Sea. The approved naming citation was published by the [[Organization:Minor Planet Center|Minor Planet Center]] on 15 December 2005 ({{small|M.P.C. 55720}}).<ref name="MPC-Circulars-Archive" />
