1087 Arabis

Heidelberg Observatory in 1927 and assigned the provisional designation 1927 RD. The asteroid was named after the flowering plant Arabis (rockcress).[15]

Discovery

Arabis was officially discovered on 2 September 1927, by German astronomer

Nikolaj Ivanov at the Simeiz Observatory on the Crimean peninsula.[3] The Minor Planet Center does not acknowledge these independent discoverers.[15]

The asteroid was first identified as A917 UE at the Simeiz Observatory in October 1917, almost 10 years prior to its official discovery observation at Heidelberg.[15]

Orbit and classification

Arabis is a member the

606),[4][5] the largest asteroid family in the outer main belt consisting of nearly 10,000 known asteroids.[16]: 23  It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,911 days). Its orbit has an eccentricity of 0.09 and an inclination of 10° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Heidelberg.[15]

Physical characteristics

In the

Rotation period

During the early 1990s, a rotational

Spin axis

Between 2011 and 2017, an international collaboration modeled three lightcurves with a period of 5.794995, 5.79500 and 5.79501 hours, respectively.[12][a][b] The more recent studies also determined two spin axis of (155.0°, 25.0°) and (331.0°, 5.0°) in ecliptic coordinates (λ, β).[a][b]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.098 and 0.2248.[6][7][8][9][10]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2137 and a diameter of 31.67 kilometers based on an absolute magnitude of 9.79.[4]
