This negative photo shows the faint image of periodic comet Halley (in the circle) at the record heliocentric distance 18.82 AU (= 2,820 million km, about the distance of Uranus). ... They were cleaned to remove various sky and instrumental noise, shifted according to the predicted motion of the comet and then co-added. ... The position in the sky is less than 1 arcsec from that predicted on the basis of the comet's very well-determined orbit. ... Total exposure time: 13,500 seconds. ...

. This color image was obtained with Fuji color film (Super Plus 400) in focal plane of the 70-cm reflector (F = 27 m) at Lisniki Observatory by A.M.Evtushevsky.

This made an accurate orbit (or orbits) difficult to determine; however, after numerous observations of the comet, astronmers determined that the comet had passed within 96,000 kilometers (60,000 miles) of the center of Jupiter or 25,000 kilometers (16,000 miles) from the cloud tops during the July 8, 1992, approach. ...

... An estimate the rotation period of cometary nuclei is important for understanding and describing the physical processes of the cometary activity. Unfortunately, the measurements of the rotation periods of the comet nucleus depend on the model assumptions and it is one of the main reasons for the scatter of the estimates given in various articles for a given comet. ...
