2035 Stearns, provisional designation Template:Mp, is a bright Hungaria asteroid and sizable Mars-crosser inside the inner regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 21 September 1973, by American astronomer James Gibson at the Leoncito Astronomical Complex in Argentina.[1] The transitional E-type asteroid has a long rotation period of 93 hours.[2] It was named after American astronomer Carl Leo Stearns.[1]
Orbit and classification
Stearns is a dynamical Hungaria asteroid, a large group that forms the innermost dense concentration of asteroids in the Solar System.[1][2] It is also a Mars-crossing asteroid, a member of the dynamically unstable group, located between the main belt and near-Earth populations, and crossing the orbit of Mars at 1.666 AU.[3]
The asteroid orbits the Sun in the inner main-belt at a distance of 1.64–2.13 AU once every 2 years and 7 months (945 days; semi-major axis of 1.88 AU). Its orbit has an eccentricity of 0.13 and an inclination of 28° with respect to the ecliptic.[3]
The body's observation arc begins with a precovery taken at Palomar Observatory in January 1954, nearly 20 years prior to its official discovery observation at Leoncito.[1]
Physical characteristics
In the Tholen classification, Stearns is a bright E-type asteroid.[3] while in the SMASS classification and Bus-DeMeo taxonomy, it is an Xe-subtype that transitions from the X-type to the E-type.[4]
Rotation period
Several rotational lightcurve of Stearns have been obtained from photometric observations since 1988.[5][6][7] Analysis of the best-rated lightcurve by Robert Stephens at the Center for Solar System Studies Template:Obscode gave a rotation period of 93 hours with a brightness amplitude of 0.20 magnitude (U=2+Script error: No such module "Check for unknown parameters".). This makes the asteroid as close slow rotator.[2]Template:Efn
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Stearns measures between 4.82 and 6.00 kilometers in diameter and its surface has an albedo between 0.443 and 0.65.[8][9] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for members of the Hungaria family of 0.40, and derives a diameter of 5.28 kilometers based on an absolute magnitude of 13.0.[2]
Naming
This minor planet was named after Carl Leo Stearns (1892–1972), American astronomer at Wesleyan University and Van Vleck Observatory who measured a large number of stellar parallaxes.[1] The official Template:MoMP was published by the Minor Planet Center on 1 November 1978 (M.P.C. 4548Script error: No such module "Check for unknown parameters".).[10] The lunar crater Stearns was also named in his honor.
