1615 Bardwell, provisional designation 1950 BW, is a rare-type Themistian

Conrad Bardwell.[2]

Orbit and classification

Bardwell is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. It orbits the Sun at a distance of 2.6–3.7 AU once every 5 years and 6 months (2,020 days). Its orbit has an eccentricity of 0.18 and an inclination of 2° with respect to the ecliptic.[1]

Its orbit has an eccentricity of 0.18 and an inclination of 2° with respect to the ecliptic.[1] It was first identified as 1926 TO at Simeiz Observatory in 1926, extending the body's observation arc by 24 years prior to its official discovery observation.[11]

Physical characteristics

In the

micron wavelength that is associated with the presence of magnetite and is what gives the asteroid its blue tint.[13] There are only a few dozens asteroids of this type known to exist.[14]

Rotation period

In the late 1970s, a rotational

As of 2017, no other photometric analysis of Bardwell has been made.

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.049 and 0.09.[4][6][7][8][10] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS, that is, an albedo of 0.0642 and a diameter of 27.78 kilometers based on an absolute magnitude of 11.38.[3]
