Levy 9 had been captured by Jupiter and was orbiting the planet at the time. Calculations showed that its unusual fragmented form was due to a previous closer approach to Jupiter in July 1992. Levy 9 passed within Jupiter’s Roche limit, and Jupiter’s tidal forces had acted to pull apart the comet. Levy 9 on the night of March 24, 1993 in a photograph taken with the 0. Shoemakers and Levy, hence its name. It was their eleventh comet discovery overall including their discovery of two non-periodic comets, which use a different nomenclature.
The discovery was announced in IAU Circular 5725 on March 27, 1993. Levy 9 was an unusual comet, as it appeared to show multiple nuclei in an elongated region about 50 arcseconds long and 10 arcseconds wide. Orbital studies of the new comet soon revealed that it was orbiting Jupiter rather than the Sun, unlike all other comets known at the time. Tracing back the comet’s orbital motion revealed that it had been orbiting Jupiter for some time. It is likely that it was captured from a solar orbit in the early 1970s, although the capture may have occurred as early as the mid-1960s.
When the comet passed Jupiter in the late 1960s or early 1970s, it happened to be near its aphelion, and found itself slightly within Jupiter’s Hill sphere. Jupiter’s gravity nudged the comet towards it. Jupiter, a distance smaller than the planet’s radius, meaning that there was an extremely high probability that SL9 would collide with Jupiter in July 1994. The discovery that the comet was likely to collide with Jupiter caused great excitement within the astronomical community and beyond, as astronomers had never before seen two significant Solar System bodies collide.
Intense studies of the comet were undertaken, and as its orbit became more accurately established, the possibility of a collision became a certainty. Comet Hyakutake, which became very bright when it passed close to the Earth in 1996. The black dot near the top is Io transiting Jupiter. Anticipation grew as the predicted date for the collisions approached, and astronomers trained terrestrial telescopes on Jupiter. Two other space probes made observations at the time of the impact: the Ulysses spacecraft, primarily designed for solar observations, was pointed towards Jupiter from its location 2.
