Orbital characteristics A

Comet Shoemaker–Levy 9 (formally designatit D/1993 F2) wis a comet that broke apairt in Julie 1992 an collidit wi Jupiter in Julie 1994, providin the first direct observation o an extraterrestrial collision o Solar Seestem objects.[2] This generatit a lairge amoont o coverage in the popular media, an the comet wis closely observed bi astronomers warldwide. The collision providit new information aboot Jupiter an heichlightit its role in reducin space debris in the inner Solar Seestem.

The comet wis discovered bi astronomers Carolyn an Eugene M. Shoemaker an David Levy.[3] Shoemaker–Levy 9 haed been capturt bi Jupiter an wis orbitin the planet at the time. It wis locatit on the nicht o Mairch 24, 1993 in a photograph taken wi the 40 cm (16 in) Schmidt telescope at the Palomar Observatory in Californie. It wis the first comet observed tae be orbitin a planet, an haed probably been capturt bi Jupiter aroond 20–30 years earlier.

Calculations shawed that its unuisual fragmentit form wis due tae a previous closer approach tae Jupiter in Julie 1992. At that time, the orbit o Shoemaker–Levy 9 passed within Jupiter's Roche leemit, an Jupiter's tidal forces haed acted tae pull apairt the comet. The comet wis later observed as a series o fragments rangin up tae 2 km (1.2 mi) in diameter. Thir fragments collidit wi Jupiter's soothren hemisphere atween July 16 an Julie 22, 1994 at a speed o approximately 60 km/s (37 mi/s) (Jupiter's escape velocity) or 216,000 km/h (134,000 mph). The prominent scars frae the impacts war mair easily veesible than the Great Reid Spot an perseestit for mony months.
