... Shortly after its discovery it was determined to be in a highly elliptical path near Jupiter and on a collision course. ... The size and mass of the original body and the individual fragments is as of this writing still highly uncertain. ... Between 16 July 1994 and 22 July 1994 the fragments impacted the upper atmosphere of Jupiter. ...

... Galileo Probe . The Galileo spacecraft was designed to study Jupiter's atmosphere, satellites, and surrounding magnetosphere for two years. ... From there, Galileo will spend more than five years traveling to Jupiter, where it will become the first spacecraft to make direct measurements from an instrumented probe within Jupiter's atmosphere. ... This image, taken by the Hubble Space Telescope, shows the predicted site at which the Galileo Probe will enter Jupiter's atmosphere on December 7, 1995. ...

... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...

Nongravitational Effects on Cometary Motion due to Jupiter . ... The problem of linking cometary apparitions before and after the approach of a comet to Jupiter was investigated. A hypothesis of possible existence of additional acceleration, perturbing the motion of comets in the vicinity of Jupiter, was considered. This nongravitational perturbation is described by a function of the jovicentric distance, written in a standard "force law" form. ...

... Comet Ikeya-Zhang, designated C/2002 C1 (Ikeya-Zhang), is named after Kaoru Ikeya of Shizuoka prefecture, Japan, and Daqing Zhang of Henan province, China, who independently discovered it on the night of 1 February 2002. A preliminary orbit reported the following day indicated that it would come moderately close to both the Earth and the Sun and that it might become visible to the naked eye during late March and April 2002. ...
