摘要：

From the perturbing effects of the asteroid (16) Psyche on the motion of the asteroid (13206) 1997GC22 the mass of (16) Psyche is determined. A close approach between these two asteroids at 0 : 00376 AU, and at a relative velocity of 0.74 km s(-1), occurred in July 1974. The value of (3.38 +/- 0.28) 10(-11) M-circle dot has been found for the mass of ( 16) Psyche, which yields a density of (6.98 +/- 0.58) g cm(-3). These values are very different from those obtained by other authors, but the mass is much closer to the value based on the IRAS estimation of ( 16) Psyche diameter and its M-type taxonomical classification.
