Abstract

The nucleus of P/Halley rotates as a slightly asymmetric top, the orientation of the rotation axis (i.e., the orientation of the angular momentum vector) is 1 = 39°, b = -54° in the ecliptic system. The error zone is a cone about this axis with a half opening angle of 15°. In the rotation of an asymmetric top the rotation axis is not fixed rigidly to the body; this means that while the nucleus rotates about the axis with the short period of 2.2 +/-.05 days, its long axis "nods" periodically with the long period of 7.4 +/-.05 days. The amplitude of the "nodding" is about 14° +/- 3° in both directions relative to a plane perpendicular to the rotation axis.
