'''1055 Tynka''', provisional designation {{mpf|1925 WG}}, is a stony Florian [[asteroid]] from the inner regions of the [[asteroid belt]], approximately 10 kilometers in diameter. It was discovered on 17 November 1925, by Czech astronomer [[Emil Buchar]] at the [[Algiers Observatory]] in North Africa, who named it after his mother Tynka Buchar.<ref name="MPC-object" />

== Orbit and classification ==
{{DEFAULTSORT:001055}}

[[Category:Main-belt asteroids]]
''Tynka'' is a member of the [[Flora family]] ({{small|[[FIN tbl#402|402]]}}), a giant [[asteroid family]] and the largest family of stony asteroids in the main belt.<ref name="Ferret" /><ref name="Nesvorny-2014" />{{rp|23}} It orbits the Sun in the [[Kirkwood gap|inner]] asteroid belt at a distance of 1.7–2.7&nbsp;[[Astronomical unit|AU]] once every 3 years and 3 months (1,190 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.21 and an [[orbital inclination|inclination]] of 5[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" />
[[Category:Minor planets named for people|Tynka]]

[[Category:Named minor planets|Tynka]]
The body's [[observation arc]] begins with its identification as {{mpf|A902 TB}} at [[Heidelberg Observatory]] in October 1902, more than 23 years prior to its official discovery observation at Algiers.<ref name="MPC-object" />
[[Category:S-type asteroids (Tholen)]]

[[Category:S-type asteroids (SMASS)]]
== Physical characteristics ==

''Tynka'' is a common stony [[S-type asteroid]] in both the [[Tholen classification|Tholen]] and [[SMASS classification]],<ref name="jpldata" /> which agrees with the overall [[Asteroid spectral type|spectral type]] for members of the Flora family.<ref name="Nesvorny-2014" />{{rp|23}}

=== Rotation period ===

Three rotational [[lightcurve]]s of ''Tynka'' were independently obtained from photometric observations by astronomers [[David Higgins (astronomer)|David Higgins]], Agnieszka Kryszczyńska and [[Robert D. Stephens|Robert Stephens]]. Lightcurve analysis gave a [[rotation period]] of 11.75 and 11.893 hours with a brightness variation between 0.06 and 0.33 [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=2-/2/2]]}}).<ref name="Stephens-2012f" /><ref name="Higgins-2009a" /><ref name="Kryszczynska-2012b" /> An alternative period solution of 5.9818 hours with an amplitude of 0.17 was measured by French amateur astronomer [[René Roy (astronomer)|René Roy]] in April 2012 ({{small|[[LCDB quality code|U=2]]}}).<ref name="geneva-obs" />

=== Diameter and albedo ===

According to the surveys carried out by the Japanese [[Akari (satellite)|Akari satellite]] and the [[NEOWISE]] mission of NASA's [[Wide-field Infrared Survey Explorer]], ''Tynka'' measures 8.95 and 13.48 kilometers in diameter and its surface has an [[astronomical albedo|albedo]] of 0.169 and 0.350, respectively.<ref name="AKARI" /><ref name="Masiero-2012" />

The ''Collaborative Asteroid Lightcurve Link'' assumes an albedo of 0.24 – derived from [[8&nbsp;Flora]], the largest member and namesake of the Flora family – and calculates a diameter of 10.31 kilometers based on an [[absolute magnitude]] of 12.1.<ref name="lcdb" />

== Naming ==

This [[minor planet]] was named by the discoverer after his mother Tynka Buchar. The official naming citation was mentioned in ''[[The Names of the Minor Planets]]'' by [[Paul Herget]] in 1955 ({{small|[[Herget's discovery circumstances|H 100]]}}). [[Emil Buchar]] worked at the Institute of Astronomy and Geophysics at the Technical University in Prague.<ref name="springer" /> This asteroid was his only minor-planet discovery.<ref name="MPC-Discoverers" />

1055 Tynka, provisional designation 1925 WG, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 17 November 1925, by Czech astronomer Emil Buchar at the Algiers Observatory in North Africa, who named it after his mother Tynka Buchar.[12]

Orbit and classification

Tynka is a member of the Flora family (402), a giant asteroid family and the largest family of stony asteroids in the main belt.[4][13]: 23  It orbits the Sun in the inner asteroid belt at a distance of 1.7–2.7 AU once every 3 years and 3 months (1,190 days). Its orbit has an eccentricity of 0.21 and an inclination of 5° with respect to the ecliptic.[1]

The body's observation arc begins with its identification as A902 TB at Heidelberg Observatory in October 1902, more than 23 years prior to its official discovery observation at Algiers.[12]

Physical characteristics

Tynka is a common stony S-type asteroid in both the Tholen and SMASS classification,[1] which agrees with the overall spectral type for members of the Flora family.[13]: 23 

Rotation period

Three rotational lightcurves of Tynka were independently obtained from photometric observations by astronomers David Higgins, Agnieszka Kryszczyńska and Robert Stephens. Lightcurve analysis gave a rotation period of 11.75 and 11.893 hours with a brightness variation between 0.06 and 0.33 magnitude (U=2-/2/2).[8][9][10] An alternative period solution of 5.9818 hours with an amplitude of 0.17 was measured by French amateur astronomer René Roy in April 2012 (U=2).[7]

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Tynka measures 8.95 and 13.48 kilometers in diameter and its surface has an albedo of 0.169 and 0.350, respectively.[5][6]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of the Flora family – and calculates a diameter of 10.31 kilometers based on an absolute magnitude of 12.1.[3]

Naming

This minor planet was named by the discoverer after his mother Tynka Buchar. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 100). Emil Buchar worked at the Institute of Astronomy and Geophysics at the Technical University in Prague.[2] This asteroid was his only minor-planet discovery.[14]
