13123 Tyson, provisional designation 1994 KA, is a stony Phocaea
Carolyn Shoemaker and Canadian astronomer David Levy at the Palomar Observatory in California, United States.[10] The asteroid was named for Neil deGrasse Tyson, American astrophysicist and popular science communicator.[2]
Orbit and classification
The stony
701),[4] a rather small group of asteroids with similar orbital characteristics, named after its largest member, 25 Phocaea. It orbits the Sun in the inner main-belt at a distance of 1.7–3.0 AU once every 3 years and 8 months (1,324 days). Its orbit has an eccentricity of 0.27 and an inclination of 23° with respect to the ecliptic.[1] The first precovery was taken at Palomar's Digitized Sky Survey (DSS) in 1953, extending the asteroid's observation arc by 41 years prior to its discovery.[10]

Satellite
Tyson is an asynchronous
minor planet moon, designated S/2015 (13123) 1 in its orbit. The satellite has a rotation period of 3.862 hours. No other physical properties for this binary system has been published.[5][6][a]
Diameter and albedo
According to the survey carried out by NASA's space-based
albedo of 0.197,[7] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.23 and calculates a smaller diameter of 8.2 kilometers with an absolute magnitude of 12.64.[3]

Notes
- ^ a b c d Pravec (2015/16): lightcurve plot of (13123) Tyson with a rotation period of 3.3303±0.0002 hours and a brightness amplitude of 0.20 mag at H= 12.19±0.09 (R) and an assigned quality code of U=3. It is an unconfirmed binary asteroid, that lacks mutual eclipse/occultation events. Two periods were derived: 3.3302 (primary, first plot) and 3.862 hours (satellite, second lightcurve plot), with an amplitude of 0.2 and 0.04 mag.
