Fragments of the comet Schumacher Levy 9 (scientific name D / 1993 F2) collided with Jupiter on July 17, 1992. In a span of six days, 21 such fragments fell on Jupiter.
The collision between two solar system objects was the first direct observation of the Schumacher Levy 9 collision. Schumacher discovered Levy 9 on the night of March 24, 1993. At the time of its discovery, it was transformed into 21 pieces by the gravitational pull of Jupiter. Schumacher Levy 9 was also the first comet to be found orbiting a planet. On July 16, 1994, the first part of the Schumacher Levy crashed into the southern hemisphere of Jupiter. Then within a week each part fell on Jupiter and on the 22nd the last part fell. The collision left Jupiter with spots larger than Earth. The energy generated by this collision would be 600 times the total nuclear stockpile of the world.
