Maja (minor planet designation : 66 Maja ) is a carbonaceous background asteroid from the central regions of the asteroid belt , approximately 71 kilometers in diameter. It was discovered on 9 April 1861, by American astronomer Horace Tuttle at the Harvard College Observatory in Cambridge, Massachusetts, United States.[21] Maia from Greek mythology.[3]
Orbit and classification [ edit ]
Maja is a non-family asteroid from the main belt's background population .[5] central asteroid belt at a distance of 2.2–3.1 AU semi-major axis of 2.65 AU ). Its orbit has an eccentricity of 0.17 and an inclination of 3° with respect to the ecliptic .[1] observation arc begins at the Harvard Observatory, one night after its official discovery observation.[21]
Physical characteristics [ edit ]
In the Tholen classification , Maja is a carbonaceous C-type asteroid ,[1] SMASS classification it is a "hydrated" carbonaceous subtype (Ch ).[1]
Rotation period and spin axes [ edit ]
Several rotational lightcurves of Maja have been obtained from photometric observations since 1988.[13] [14] [15] [17] [18] rotation period of 9.73509 hours with a brightness amplitude of 0.25 magnitude (U=3 [4] [15]
In 2016, a modeled lightcurve was derived from various photometric database sources, giving a concurring sidereal period of 9.73570 hours and two spin axes of (49.0°, −70.0°) and (225.0°, −68.0°) in ecliptic coordinates .[16]
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 , Maja measures between 62.87 and 82.28 kilometers in diameter and its surface has an albedo between 0.03 and 0.0759.[6] [7] [8] [9] [10] [11]
The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0618 and a diameter of 71.82 kilometers based on an absolute magnitude of 9.36.[4] [9]
This minor planet was named by Harvard 's former president, J. Quincy, after Maia , one of the Seven Sisters of the Pleiades in Greek mythology . She is the mother of Hermes (Mercury) and the daughter of Atlas and Pleione . The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 10 [3]
The asteroids 130 Elektra , 233 Asterope and 1051 Merope were also named after the mythological Seven Sisters. In 1861, the director of the discovering observatory, George Phillips Bond , raised a minor concern since these names had already been applied to some of the brightest stars of the Pleiades in the constellation of Taurus: Maia , Electra , Asterope and Merope .[3]
Spacecraft visits [ edit ]
At present, Maja has not been visited by any spacecraft. As of 1988, mission planning for the Cassini–Huygens spacecraft included a flyby of Maja while leaving the inner solar system in March 1997, however due to delays, the launch of Cassini-Huygens was moved from April 1996 to October 1997, thus negating the option to pass near Maja . Cassini-Huygens passed by asteroid 2685 Masursky on 23 January 2000 instead.[22]
