4.According to paragraph 3, the tails of a comet A. flow in the same direction as the radiation that produces them B. become straighter as the comet moves away from the Sun C. are pulled toward the Sun D. can become detached from the comet head if the solar winds are strong enough ...
Since a comet loses matter on each pass by the Sun, eventually it will be depleted to the point where it is no longer visible. Comets that approach the Sun have finite lifetimes. Given the typical sizes of comets and the typical rates at which they lose matter, astronomers have concluded ...
We propose that the sodium tail in March 1997 was produced by the release of sodium atoms from grains in the dust tail.doi:10.1029/97GL03704Wilson, J. K.Baumgardner, J.Mendillo, M.Geophysical Research LettersJK Wilson,J Baumgardner,M Mendillo.Three tails of comet Hale-Bopp. Geophysical ...
Tail end, the latter end; the termination; as, the tail end of a contest. [Colloq.] Tail joist. (Arch.) Same as Tailpiece. Tail of a comet (Astron.), a luminous train extending from the nucleus or body, often to a great distance, and usually in a direction opposite to the sun....
Tait advances the opinion that the tail of a comet consists of nothing but meteorites; mentioning in proof of this that the orbits of the August and November meteors have been determined, and found to be identical with those of two known comets. I do not question the importance of this ...

The main components of a comet – nucleus, coma, hydrogen envelope, dust and plasma tails – indicating their composition, relative sizes and location. Credit: ESA When Solar Orbiter crosses the dust tail, depending on its density – which is extremely difficult to predict – it is possible th...
Comet tailscome in two types. The large and often curved tails, an example of which is shown inFig. 8, are type II tails and are composed of dust. Dust particles are typically ejected from the surface of a comet by the gas jets created by warming frozen volatiles. This gas-powered eje...
Comet Tails:Comets often leave behind two tails, one of gases that sublimate off the surface, and one of rocks and other debris. The debris tail of a comet can cause meteor showers on Earth, while the tail of gases is always pointed away from the Sun.Answer and Explanation: ...
