A member of the solar system which usually moves in an elongated orbit, approaching very near to the sun in its perihelion, and receding to a very great distance from it at its aphelion. A comet commonly consists of three parts: the nucleus, the envelope, or coma, and the tail; but one or more of these parts is frequently wanting. See Illustration in Appendix.
Sensual pleasures have the fleeting brilliance of a comet; a happy marriage has the tranquillity of a lovely sunset. Ann Landers
I've had experiences in my life that leave no doubt in my mind about the fact that God exists. I'm quite willing to debate people who don't think so because I want them to explain to me how did our solar system get so organized and how is the universe so complex and yet well-organized that we can predict 70 years hence when a comet is coming? Benjamin Carson
I have worn myself thin trying to find out about this comet, and I know very little now in the matter. Maria Mitchell
I have just gone over my comet computations again, and it is humiliating to perceive how very little more I know than I did seven years ago when I first did this kind of work. Maria Mitchell
I saw, in looking over Cooper, elements of a comet of 1825 which resemble what I get out for this, from my own observations, but I cannot rely upon my own. Maria Mitchell
