3402 Wisdom, provisional designation 1981 PB, is a stony asteroid and Mars-crosser on an eccentric orbit from the inner regions of the asteroid belt, approximately 2.5 kilometers (1.6 miles) in diameter. It was discovered on 5 August 1981, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, in the United States.[3] The presumed bright S-type asteroid has a rotation period of 4.99 hours.[4] It was named after American planetary scientist Jack Wisdom.[2]

## Orbit and classification

Wisdom is a Mars-crossing asteroid, a member of a dynamically unstable group, located between the main belt and the near-Earth populations, and crossing the orbit of Mars at 1.666 AU. It orbits the Sun at a distance of 1.5–2.7 AU once every 3 years and 1 month (1,137 days; semi-major axis of 2.13 AU). Its orbit has an eccentricity of 0.28 and an inclination of 5° with respect to the ecliptic.[1]

The body's observation arc begins with a precovery taken at Palomar Observatory in February 1977, more than 4 years prior to its official discovery observation at Anderson Mesa.[3]

## Physical characteristics

Wisdom is an assumed stony S-type asteroid.[4]

### Rotation period

In October 2006, two rotational lightcurves of Wisdom were obtained from photometric observations at Ondřejov, Skalnaté pleso and Carbuncle Hill observatories (912;I00). Lightcurve analysis gave a well-defined rotation period of 4.9949 and 4.9951 hours with a high brightness variation of 0.75 and 0.74 magnitude, respectively ({{{1}}}).[7][lower-alpha 1] A high brightness amplitude typically indicate that the body has an elongated rather than spherical shape.

### Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Wisdom measures 2.05 and 2.50 kilometers in diameter and its surface has an albedo of 0.32 and 0.283, respectively.[5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 2.59 kilometers based on an absolute magnitude of 15.34.[4]

With a mean diameter of approximately 2.5 kilometers, Wisdom is one of the smaller mid-sized Mars-crossing asteroids. It is assumed that there are up to 10 thousand Mars-crossers larger than 1 kilometer.[10] The largest members of this dynamical group are 132 Aethra, 323 Brucia, 2204 Lyyli and 512 Taurinensis, which measure between 43 and 25 kilometers in diameter.

## Naming

This minor planet was named after Jack Wisdom (born 1953), a dynamicist and professor of planetary sciences at MIT. Wisdom pioneered in the study of the dynamics and long-term stability of the Solar System, and demonstrated the dynamical mechanism for the clearing of asteroid in the Kirkwood gaps of the asteroid belt.[2] The official naming citation was published by the Minor Planet Center on 2 February 1988 (M.P.C. 12803).[11]
