A comet is an object that travels through space. It is composed of a solid core with a long "tail." Its core, or nucleus, consists of rock, dust. and ice. Its tail is a trailing cloud of dust and gas. In 1993, astronomers identified a previously unknown comet, which was given the name Shoemaker-Levy 9. They calculated its orbit and realized that the comet would soon collide with the planet Jupiter. In the summer of 1994, they prepared to observe the impact.
Shoemaker-Levy 9 was not a typical comet. Astronomers defermined that previously, most likely in about 1929, the comet had come close
to Jupiter. The tremendous pull of the planet's gravity shattered the comet's nucleus into about 21 pieces, permanently changing the comet's appearance. Unlike most comets, which have a nucleus that looks like a single point of light, Shoemaker-Levy 9 had a nucleus that resembled a string of glowing beads.
In 1994, these fragments slammed into Jupiter's atmosphere when the comet's orbit again brought it near the planet. The collision occurred on a side of Jupiter that was out of view of Earth-based telescopes. However, within a few hours, the planet had rotated so that astronomers could observe the impact sites. The sites looked like dark patches on the planet. The dark patches were actually clouds composed of comet dust and gases, which remained visible for months.
Choose the two central ideas developed in the passage.

Answers

Answer 1

NASA's plans to reduce the risk of an impact on Earth were influenced by Comet Shoemaker-Levy 9, which demonstrated that massive impacts still occur in the Solar System.

A comet is what?

Comets are solar system-orbiting icy balls of rock, gas, and dust. They resemble a small town in size when frozen.

Further investigations indicated the comet, which was initially thought to be a single entity, had made a near approach to Jupiter in July 1992 and had been shattered by tidal forces brought on by the planet's strong gravity. It was believed that the comet spent around ten years orbiting Jupiter before it was destroyed.
