3401 Vanphilos, provisional designation 1981 PA, is a stony, eccentric
Mars-crosser, approximately 7 kilometers in diameter. It was discovered on 1 August 1981, by and at Harvard's Oak Ridge Observatory (Agassiz Station) in Massachusetts, United States.[3]
Orbit and classification
Vanphilos orbits the Sun in the
Turku Observatory, extending the body's observation arc by 35 years prior to its official discovery at Harvard.[3]
Physical characteristics
In the
SMASS taxonomy, Vanphilos is characterized as a common S-type asteroid.[1]
Rotation period

Diameter and albedo
According to the survey carried out by NASA's
albedo of 0.377 and 0.31, respectively.[5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 10.30 kilometers, as the lower the body's albedo (reflectivity), the larger its diameter, at a constant absolute magnitude.[4]
