Comet

A comet is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles. The coma and tail are much larger and, if sufficiently bright, may be seen from the Earth without the aid of a telescope. Comets have been observed and recorded since ancient times by many cultures.

Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the next nearest star. Long-period comets are directed towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung out to interstellar space.

Comet (pinball)

Comet is a pinball machine released by Williams in June 1985. It was designed by Barry Oursler.

Rules

In this pinball game, the player attempts to navigate throughout a representation of a Carnival, with the namesake Comet being a central ramp representing a roller coaster, normally worth 10,000 points. Two banks of Shooting Gallery targets (Rabbits and Ducks) can be targeted to score points and advance the matching bonus counter. Each bonus track is worth a maximum of 63,000 points. Hitting all four targets in a target bank lights an additional objective, which allows you to collect the matching bonus during play by completing the Whirlwind ramp (for Ducks) or the Funhouse saucer (for Rabbits). Completing both target banks lights additional points for the center ramp (30,000, 50,000, 100,000, and one more 100,000 per sequential shot), including the chance for extra balls and replays depending on specific game settings. Completing the ramp advances both bonuses.

The most definitive feature of Comet is a Motorcycle Jump ramp on the upper-right side of the playfield. This features a Skee ball-like scoring setup, where the closest target is worth 20,000, the middle target is worth 50,000, and the farthest target is worth 200,000. Completing the ramp advances both bonuses. The ramp starts each ball in a lit state, then becomes unlit after being scored.
