'''517 Edith''', provisional designation {{mpf|1903 MH}}, is a carbonaceous background [[asteroid]] from the outer regions of the [[asteroid belt]], approximately 83 kilometers in diameter. It was discovered on 22 September 1903, by American astronomer [[Raymond Dugan]] at the [[Heidelberg-Königstuhl State Observatory]] in southwest Germany, who named it after his sister Edith Eveleth.<ref name="MPC-object" />
'''517 Edith''' is a [[minor planet]] orbiting the [[Sun]].


== Orbit and classification ==
==References==

{{Reflist}}
''Edith'' orbits the Sun in the [[Kirkwood gap|outer]] main-belt at a distance of 2.6–3.7&nbsp;[[Astronomical unit|AU]] once every 5 years and 7 months (2,050 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.18 and an [[orbital inclination|inclination]] of 3[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" />

The body's [[observation arc]] begins at Heidelberg, five days after its official discovery observation (first recorded observation at the [[Minor Planet Center|MPC]]).<ref name="MPC-object" />

== Physical characteristics ==

In the [[Tholen classification|Tholen taxonomy]], ''Edith'' is an [[X-type asteroid]].<ref name="jpldata" /> Due to its very low [[Astronomical albedo|albedo]], a more specific [[P-type asteroid|P-type]] is derived by the LCDB,<ref name="lcdb" /> while a spectroscopic survey of Tholen X-type asteroids characterizes ''Edith'' as a [[C-type asteroid]].<ref name="Fornasier-2011a" />

=== Rotation period ===

In October 2009, the best-rated rotational [[lightcurve]] of ''Edith'' was obtained from photometric observations by French amateur astronomer Maurice Audejean at his Chinon Observatory ({{small|[[IAU code#B92|B92]]}}) in Chinon, France. Lightcurve analysis gave a well-defined [[rotation period]] of 9.2747 hours with a brightness variation of 0.16 [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=3]]}}), indicating that the body is rather spheroidal.<ref name="geneva-obs" />

Additional measurements of the asteroid's period were made by French amateur astronomers [[René Roy (astronomer)|René Roy]] and [[Laurent Bernasconi]], as well as by American astronomer Robert Koff at his Antelope Hills Observatory in Bennett, Colorado ({{small|[[IAU code#H09|H09]]}}) and by Alan W. Harris of the Earth and Planetary Physics Group at [[JPL]] in the 1980s ({{small|[[LCDB quality code|U=2/2/2/2]]}}).<ref name="Harris-1992" /><ref name="geneva-obs" /><ref name="Koff-2005" />

=== 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]], ''Edith'' measures between 79.72 and 111.89 kilometers in diameter and its surface has a low [[Astronomical albedo|albedo]] between 0.026 and 0.05.<ref name="Nugent-2015" /><ref name="Nugent-2016" /><ref name="AKARI" /><ref name="SIMPS" /><ref name="Masiero-2012" />

The ''Collaborative Asteroid Lightcurve Link'' derives an albedo of 0.0397 and a diameter of 83.24 kilometers based on an [[absolute magnitude]] of 9.52.<ref name="lcdb" />

== Naming ==

This [[minor planet]] was named by the discoverer after his sister Edith Eveleth (née Dugan). The official naming citation was mentioned in ''[[The Names of the Minor Planets]]'' by [[Paul Herget]] in 1955 ({{small|[[Herget's discovery circumstances|H 55]]}}). Edith Eveleth also proposed and prepared the naming citation for Raymond Dugan's first discovery, {{MoMP|497|497 Iva}}.<ref name="springer" />

517 Edith, provisional designation 1903 MH, is a carbonaceous background asteroid from the outer regions of the asteroid belt, approximately 83 kilometers in diameter. It was discovered on 22 September 1903, by American astronomer Raymond Dugan at the Heidelberg-Königstuhl State Observatory in southwest Germany, who named it after his sister Edith Eveleth.[15]

Orbit and classification

Edith orbits the Sun in the outer main-belt at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,050 days). Its orbit has an eccentricity of 0.18 and an inclination of 3° with respect to the ecliptic.[1]

The body's observation arc begins at Heidelberg, five days after its official discovery observation (first recorded observation at the MPC).[15]

Physical characteristics

In the Tholen taxonomy, Edith is an X-type asteroid.[1] Due to its very low albedo, a more specific P-type is derived by the LCDB,[3] while a spectroscopic survey of Tholen X-type asteroids characterizes Edith as a C-type asteroid.[12]

Rotation period

In October 2009, the best-rated rotational lightcurve of Edith was obtained from photometric observations by French amateur astronomer Maurice Audejean at his Chinon Observatory (B92) in Chinon, France. Lightcurve analysis gave a well-defined rotation period of 9.2747 hours with a brightness variation of 0.16 magnitude (U=3), indicating that the body is rather spheroidal.[10]

Additional measurements of the asteroid's period were made by French amateur astronomers René Roy and Laurent Bernasconi, as well as by American astronomer Robert Koff at his Antelope Hills Observatory in Bennett, Colorado (H09) and by Alan W. Harris of the Earth and Planetary Physics Group at JPL in the 1980s (U=2/2/2/2).[9][10][11]

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, Edith measures between 79.72 and 111.89 kilometers in diameter and its surface has a low albedo between 0.026 and 0.05.[4][5][6][7][8]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0397 and a diameter of 83.24 kilometers based on an absolute magnitude of 9.52.[3]

Naming

This minor planet was named by the discoverer after his sister Edith Eveleth (née Dugan). The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 55). Edith Eveleth also proposed and prepared the naming citation for Raymond Dugan's first discovery, 497 Iva.[2]
