'''2207 Antenor''' |
'''2207 Antenor''' {{IPAc-en|æ|n|ˈ|t|iː|n|ər}} is a large [[Jupiter trojan]] from the [[Trojan camp]], approximately {{convert|92|km|mi|abbr=off|sp=us}} in diameter. It was discovered on 19 August 1977, by Russian astronomer [[Nikolai Chernykh]] at the [[Crimean Astrophysical Observatory]] in Nauchnyj on the Crimean peninsula.<ref name="MPC-object" /> The dark [[D-type asteroid]] is one of the [[#Largest Jupiter trojans|30 largest Jupiter trojans]] and has a [[rotation period]] of 7.97 hours.<ref name="lcdb" /> It was named for the Trojan hero and sage [[Antenor (mythology)|Antenor]], from Greek mythology.<ref name="springer" /> In October 2018, it was reported that ''Antenor'' is likely a [[Binary asteroid|binary system]]. If confirmed, it would be 5th known binary Jupiter trojan.<ref name="Stephens-2018" /> |
||
The dark and reddish body is classified as a [[D-type asteroid|D-type]] asteroid in the [[Tholen classification|Tholen]] taxonomic scheme. This [[Asteroid spectral types|spectral type]] is rather rare with only 46 bodies known as of 2016.<ref name="SBDB-D-type-list" /> The Jupiter trojan is orbiting in the trailering Trojan camp, at Jupiter's {{L5}} [[Lagrangian point]], 60[[Degree (angle)|°]] behind its orbit ''(see [[Trojans in astronomy]])''. It orbits the Sun at a distance of 5.1–5.2 [[Astronomical unit|AU]] once every 11 years and 8 months (4,256 days). Its orbit has a very low [[orbital eccentricity|eccentricity]] of 0.02 and an [[orbital inclination|inclination]] of 7° with respect to the [[ecliptic]].<ref name="jpldata" /> The asteroid's [[observation arc]] begins with its discovery in 1977. The first unused [[precoveries]] were taken at [[Lowell Observatory]] and the discovering observatory in 1959 and 1971, respectively.<ref name="MPC-Antenor" /> |
|||
== Orbit and classification == |
|||
[[Photometry (astronomy)|Photometric]] observations of this asteroid were taken in October 1989, by astronomers Mario Di Martino and Maria Gonano–Beurer with the now decommissioned [[La Silla Observatory#Former telescopes|ESO 1-metre telescope]] at [[La Silla]], Chile. The [[light-curve]] bulit from these observations showed a [[rotation period]] of {{val|7.965|0.002}} hours with a brightness variation of {{val|0.09|0.01}} [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=2+]]}}).<ref name="Mottola-2011" /> Two rotational light-curves in the R and S-band were obtained at the [[Palomar Transient Factory]] in September 2012, which rendered a period of {{val|7.9656|0.0103}} and {{val|7.9604|0.0103}} hours with and amplitude of 0.12 and 0.15, respectively ({{small|[[LCDB quality code|U=2/2]]}}).<ref name="Waszczak-2016" /> The most recent observation by Robert Stephens at CS3 in February 2016, gave a period of {{val|7.906|0.009}} hours with an amplitude of 0.09 ({{small|[[LCDB quality code|U=n.a.]]}}).{{efn|name=lcdb-Stephens}} |
|||
''Antenor'' is a dark Jovian [[asteroid]] orbiting in the trailing [[Trojan camp]] at Jupiter's {{L5}} [[Lagrangian point]], 60[[degree (angle)|°]] behind its orbit in a [[Orbital resonance|1:1 resonance]] {{crossreference|(see [[Trojans in astronomy]])}}. It is also a non-[[Asteroid family|family]] asteroid from the [[background asteroid|Jovian background population]].<ref name="AstDys-object" /><ref name="Ferret" /> |
|||
According to the space-based surveys carried out by the Infrared Astronomical Satellite [[IRAS]], the Japanese [[Akari (satellite)|Akari]] satellite, and NASA's [[Wide-field Infrared Survey Explorer]] with its subsequent [[NEOWISE]] mission, the asteroid measures between 85.1 and 97.7 kilometers in diameter and has an [[astronomical albedo|albedo]] of 0.051–0.068.<ref name="SIMPS" /><ref name="AKARI" /><ref name="WISE" /> The ''Collaborative Asteroid Lightcurve Link'' adopts the results obtain by the 9 observations made by IRAS, that is a diameter of 85.1 kilometer and an albedo of 0.068.<ref name="lcdb" /> |
|||
It orbits the Sun at a distance of 5.1–5.2 [[Astronomical unit|AU]] once every 11 years and 8 months (4,263 days; [[semi-major axis]] of 5.15 AU). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.02 and an [[orbital inclination|inclination]] of 7[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> The asteroid was first observed in a [[precovery]] taken at [[Lowell Observatory]] in March 1959. The body's [[observation arc]] begins with its official discovery observation at Nauchnij in August 1977.<ref name="MPC-object" /> |
|||
The minor planet is named after [[Antenor (mythology)|Antenor]], one of the wisest of the elders and counselor of King Priam of Troy. Sympathetic to a negotiated peace with the Greeks, he advised his countrymen to return [[Helen of Troy]] to Menelaus during the [[Trojan War]].<ref name="springer" /> In later accounts Antenor was made an open traitor, who unsealed the gates of Troy to the Greek enemy. Naming citation was published on 1 March 1981 ({{small|[[Minor Planet Circulars|M.P.C.]] 5849}}).<ref name="MPC-Circulars-Archive" /> The minor planets [[884 Priamus]], [[101 Helena]] and [[1647 Menelaus]] are also named after these figures from Greek mythology. |

This [[minor planet]] is named after [[Antenor (mythology)|Antenor]], one of the wisest of the elders and counselor of King [[Priam]] of Troy. Sympathetic to a negotiated peace with the Greeks, he advised his countrymen to return [[Helen of Troy]] to Menelaus during the [[Trojan War]].<ref name="springer" /> {{crossreference|(The minor planets [[884 Priamus]], [[101 Helena]] and [[1647 Menelaus]] are also named after these figures from Greek mythology.)}} In later accounts, Antenor was made an open traitor, who unsealed the gates of Troy to the Greek enemy. The official {{MoMP|2207|naming citation}} was published by the [[Minor Planet Center]] on 1 March 1981 ({{small|[[Minor Planet Circulars|M.P.C.]] 5849}}).<ref name="MPC-Circulars-Archive" /> |
|||
== Physical characteristics == |
|||
''Antenor'' is classified as a dark [[D-type asteroid]] in the [[Tholen classification|Tholen]] and Barucci taxonomy (latter as "D0").<ref name="jpldata" /><ref name="Ferret" /> |
|||
=== Lightcurves === |
|||
The first rotational [[lightcurve]]s of ''Antenor'' were obtained from [[Photometry (astronomy)|photometric]] observations in October 1989, by astronomers Mario Di Martino and Maria Gonano–Beurer with the now decommissioned [[ESO 1-metre telescope]] at [[La Silla Observatory|La Silla]] in Chile.<ref name="Mottola-2011" /><ref name="Gonano-1991" /> In April 1969, a follow-up observation by Mottola gave the so-far best-rated [[rotation period]] of in 7.965 hours with a brightness variation of 0.09 [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=2+]]}}).<ref name="lcdb" /><ref name="Mottola-2011" /> |
|||
In September 2012, by astronomers at the [[Palomar Transient Factory]] derived two concurring period of {{val|7.960}} {{val|7.964}} hours with an amplitude of 0.12 and 0.15 in the R- and S-band respectively ({{small|[[LCDB quality code|U=2/2]]}}).<ref name="lcdb" /><ref name="Waszczak-2015" /> Between 2016 and 2018, observation by [[Robert D. Stephens|Robert Stephens]] at the [[Center for Solar System Studies]], California, gave rotation period of 7.906, 7.964 hours with an amplitude of 0.09 ({{small|[[LCDB quality code|U=2+/2+/n.a.]]}}).<ref name="Stephens-2016j" /><ref name="Stephens-2017f" />{{efn|name=lightcurve-plots-Stephens}} |
|||
==== Unconfirmed satellite ==== |
|||
In October 2018, Stephens, in collaboration with [[Brian D. Warner|Brian Warner]] {{Obscode|716}} and several other European observers including Amadeo Aznarand {{Obscode|Z95}}/{{Obscode|J42}} and Vladimir Benishek at [[Belgrade Observatory]], reported that ''Antenor'' is likely a [[Binary asteroid|binary system]]. An orbital period for the suspected [[minor-planet moon]] could not be determined. If confirmed, it would be 5th known binary Jupiter trojan.<ref name="Stephens-2018" /> |
|||
=== Diameter and albedo === |
|||
According to the surveys carried out by the Infrared Astronomical Satellite [[IRAS]], the Japanese [[Akari (satellite)|Akari satellite]] and the [[NEOWISE]] mission of NASA's [[Wide-field Infrared Survey Explorer]], ''Antenor'' measures between 85.11 and 97.66 kilometers in diameter and its surface has an [[astronomical albedo|albedo]] between 0.051 and 0.0678.<ref name="SIMPS" /><ref name="AKARI" /><ref name="Grav-2012" /> The ''Collaborative Asteroid Lightcurve Link'' an albedo of 0.0678 and a diameter of 85.11 kilometers based on an [[absolute magnitude]] of 8.89.<ref name="lcdb" /> |

2207 Antenor /ænˈtiːnər/ is a large Jupiter trojan from the Trojan camp, approximately 92 kilometers (57 miles) in diameter. It was discovered on 19 August 1977, by Russian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[1] The dark D-type asteroid is one of the 30 largest Jupiter trojans and has a rotation period of 7.97 hours.[5] It was named for the Trojan hero and sage Antenor, from Greek mythology.[3] In October 2018, it was reported that Antenor is likely a binary system. If confirmed, it would be 5th known binary Jupiter trojan.[8]
Orbit and classification
[edit]Antenor is a dark Jovian asteroid orbiting in the trailing Trojan camp at Jupiter's L5 Lagrangian point, 60° behind its orbit in a 1:1 resonance . It is also a non-family asteroid from the Jovian background population.[7][17]
It orbits the Sun at a distance of 5.1–5.2 AU once every 11 years and 8 months (4,263 days; semi-major axis of 5.15 AU). Its orbit has an eccentricity of 0.02 and an inclination of 7° with respect to the ecliptic.[4] The asteroid was first observed in a precovery taken at Lowell Observatory in March 1959. The body's observation arc begins with its official discovery observation at Nauchnij in August 1977.[1]
Naming
[edit]This minor planet is named after Antenor, one of the wisest of the elders and counselor of King Priam of Troy. Sympathetic to a negotiated peace with the Greeks, he advised his countrymen to return Helen of Troy to Menelaus during the Trojan War.[3] In later accounts, Antenor was made an open traitor, who unsealed the gates of Troy to the Greek enemy. The official naming citation was published by the Minor Planet Center on 1 March 1981 (M.P.C. 5849).[20]
Physical characteristics
[edit]Antenor is classified as a dark D-type asteroid in the Tholen and Barucci taxonomy (latter as "D0").[4][17]
Lightcurves
[edit]The first rotational lightcurves of Antenor were obtained from photometric observations in October 1989, by astronomers Mario Di Martino and Maria Gonano–Beurer with the now decommissioned ESO 1-metre telescope at La Silla in Chile.[15][16] In April 1969, a follow-up observation by Mottola gave the so-far best-rated rotation period of in 7.965 hours with a brightness variation of 0.09 magnitude (U=2+).[5][15]
In September 2012, by astronomers at the Palomar Transient Factory derived two concurring period of 7.960 7.964 hours with an amplitude of 0.12 and 0.15 in the R- and S-band respectively (U=2/2).[5][13] Between 2016 and 2018, observation by Robert Stephens at the Center for Solar System Studies, California, gave rotation period of 7.906, 7.964 hours with an amplitude of 0.09 (U=2+/2+/n.a.).[12][14][a]
Unconfirmed satellite
[edit]In October 2018, Stephens, in collaboration with Brian Warner (716) and several other European observers including Amadeo Aznarand (Z95)/(J42) and Vladimir Benishek at Belgrade Observatory, reported that Antenor is likely a binary system. An orbital period for the suspected minor-planet moon could not be determined. If confirmed, it would be 5th known binary Jupiter trojan.[8]
Diameter and albedo
[edit]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, Antenor measures between 85.11 and 97.66 kilometers in diameter and its surface has an albedo between 0.051 and 0.0678.[9][10][11] The Collaborative Asteroid Lightcurve Link an albedo of 0.0678 and a diameter of 85.11 kilometers based on an absolute magnitude of 8.89.[5]
