'''1094 Siberia''', provisional designation {{mpf|1926 CB}}, is an Eunomian [[asteroid]] from the central regions of the [[asteroid belt]], approximately 18 kilometers in diameter. It was discovered on 12 February 1926, by Soviet astronomer [[Sergey Belyavsky]] at the [[Simeiz Observatory]] on the Crimean peninsula.<ref name="MPC-object" /> The asteroid was named after the vast region of [[Siberia]] in North Asia.<ref name="springer" />
'''1094 Siberia''' is a [[minor planet]] orbiting the [[Sun]]. Initially it received the designation ''1926 CB''. It is a member of the [[Eunomia family]]

== Orbit and classification ==


''Siberia'' is a member of the [[Eunomia family]] ({{small|[[FIN tbl#502|502]]}}),<ref name="Ferret" /> a prominent [[Asteroid family|family]] of stony asteroids and the largest one in the intermediate main belt with more than 5,000 members.<ref name="Nesvorny-2014" />{{rp|23}} It orbits the Sun in the [[Kirkwood gap|central]] main-belt at a distance of 2.2–2.9&nbsp;[[Astronomical unit|AU]] once every 4 years and 1 month (1,483 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.13 and an [[orbital inclination|inclination]] of 14[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" />
{{mpf|1094 Siberia}} is mentioned briefly in [[John Varley (author)|John Varley]]'s science fiction novel ''Rolling Thunder'', where it is described as "an escape-proof prison" of the Republic of Mars.


The asteroid was first identified as {{mpf|A918 EJ}} at [[Heidelberg Observatory|Heidelberg]] or Simeiz in March 1918. The body's [[observation arc]] begins at Heidelberg in June 1935, more than 9 years after its official discovery observation at Simeiz.<ref name="MPC-object" />

1094 Siberia, provisional designation 1926 CB, is an Eunomian asteroid from the central regions of the asteroid belt, approximately 18 kilometers in diameter. It was discovered on 12 February 1926, by Soviet astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[12] The asteroid was named after the vast region of Siberia in North Asia.[2]

Orbit and classification

Siberia is a member of the Eunomia family (502),[4] a prominent family of stony asteroids and the largest one in the intermediate main belt with more than 5,000 members.[13]: 23  It orbits the Sun in the central main-belt at a distance of 2.2–2.9 AU once every 4 years and 1 month (1,483 days). Its orbit has an eccentricity of 0.13 and an inclination of 14° with respect to the ecliptic.[1]

The asteroid was first identified as A918 EJ at Heidelberg or Simeiz in March 1918. The body's observation arc begins at Heidelberg in June 1935, more than 9 years after its official discovery observation at Simeiz.[12]

Physical characteristics

In the SMASS classification, Siberia is a Xk-subtype, that transitions from the X-type to the K-type asteroids,[1] while the overall spectral type of the Eunomia family is that of a stony S-type asteroid.[13]: 23  It is also an assumed X-type.[3]

Slow rotation

In December 2006, a first rotational lightcurve of Siberia was obtained from photometric observations by astronomers from New Zealand and Australia. Lightcurve analysis gave a rotation period of 21.15 hours with a brightness amplitude of 0.45 magnitude, indicating a non-spherical shape (U=2).[10] While not being a slow rotator, Siberia has a longer than average rotation period, especially for its size.[10]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Siberia measures between 17.08 and 18.79 kilometers in diameter and its surface has an albedo between 0.089 and 0.127.[5][6][7][8][9]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1227 and a diameter of 18.16 kilometers based on an absolute magnitude of 11.6.[3]

Naming

This minor planet was named after the vast geographic region of Siberia in North Asia, approximately 13.1 million square kilometres (5,100,000 sq mi) in area. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 103).[2]
