Could it bring a collision with a comet, a deadly solar storm, or worse?
"The golden boy," they called him; a comet lighting up the sky.
Are we going to say, ‘Here comes Haley’s comet, let's make a regulation!
When the comet arrives, they band together and face apocalypse as a family.
They found that there are roughly 1,900 hydrogen atoms for each deuterium atom in the water on comet 67P.
A star like a comet, threatens ruin by war, and death by pestilence.
Then he went back to the telescope and picked up the comet again.
In spite of it, row upon row of houses burned with a fury that lit the whole scene with a glow that was like the comet's own.
The 1811 comet has a period of 3000 years, while that of 1844 has a period of over 10,000 years.
Should the comet strike the earth obliquely, it would glance off, and the consequences would be partial.
c.1200, from Old French comete (12c., Modern French comète), from Latin cometa, from Greek (aster) kometes, literally "long-haired (star)," from kome "hair of the head" (cf. koman "let the hair grow long"), of unknown origin. So called from resemblance of a comet's tail to streaming hair.
A celestial object that orbits the Sun along an elongated path. A comet that is not near the Sun consists only of a nucleus—a solid core of frozen water, frozen gases, and dust. When a comet comes close to the Sun, its nucleus heats up and releases a gaseous coma that surrounds the nucleus. A comet forms a tail when solar heat or wind forces dust or gas off its coma, with the tail always streaming away from the Sun. ◇ Short-period comets have orbital periods of less than 200 years and come from the region known as the Kuiper belt. Long-period comets have periods greater than 200 years and come from the Oort cloud. See more at Kuiper belt, Oort cloud. See Note at solar system.
An object that enters the inner solar system, typically in a very elongated orbit around the sun. Material is boiled off from the comet by the heat of the sun, so that a characteristic tail is formed. The path of a comet can be in the form of an ellipse or a hyperbola. If it follows a hyperbolic path, it enters the solar system once and then leaves forever. If its path is an ellipse, it stays in orbit around the sun.
Note: Comets were once believed to be omens, and their appearances in the sky were greatly feared or welcomed.
Note: The most famous comet, Comet Halley (or Halley's comet), passes close to the Earth roughly every seventy-six years, most recently in 1986.
