the coma of a comet is the "dusty" atmosphere around a comets head much much larger than the comet itself. The coma is formed by the interaction of the sun that causes gases to release from the nucleus of the comet as well as sublimation of ices.
Comets are small bodies of rock and ice which are in a highly eccentric orbit around the sun. They spend most of their time slowly orbiting the sun, far out beyond the outer planets. Their orbit eventually comes close to the sun, where the surface is heated and gives the comet its tails. They are thought to be objects from the Kuiper belt, a group of icy rocks far out beyond the orbit of Neptune. Gravitational effects of the planets and other objects may knock these off their regular orbits into the highly eccentric comet orbit.
-Asteroids are minor planets, Minor planet is an astronomical object in direct orbit around the sun that is neither a planet nor originally classified as a comet
-Comets are an icy small solar system body that went passing close to the sun
-Meteors are a small rocky or metalic body traveling through space
Comet is like a bright head with a long tail-millions of kms.the tail is always away from the sun &grows when approaches the sun.these move in elliptical orbits& their revolution period is longer.comets appear to us periodically, 1 eg. is-Halley's comet--which appears once in 76 years.it was seen last in 1986.this was discovered by Halley.guess when it appears again...! comets were thought to originate in the icy & a dry place called the "OORT CLOUD", more than 100 light years (its distance) from the solar system,4 to5 billion years ago;& new ones are even taking their birth from their parents' collision!
Comet are chunk of ice and dust whose orbit are usually very long,narrowellipses
The coma of a comet is made of heated gases and dust.
The tail of the comet is not the coma, it is just called the tail. The coma is the fuzzy, bullet like head of the comet.
A coma of a comet is the fuzzy, gaseous head of a comet. It is formed when a comet approaches our sun, and solar energy begins to vaporize the ices, producing the coma.
A cloud of gas surrounding the nucleus.
heat from the sun
The three main parts of a comet are the nucleus, coma, and tail. The nucleus is the head of the comet, the coma is the middle, and the tail is the end of the comet.
This is the coma, the portion of the comet that sublimates from the surface as it approaches the sun.
The Coma is the nebulous envelope around the nucleus of a comet. It is formed when the comet passes close to the Sun.
An AuraThe "Coma".
The coma is the cloud of gas and dust that surrounds the nucleus of a comet. This is caused by the Sun heating the icy surface of the comet, which sublimates into gas and throws off dust. Some comets have small explosions, almost like eruptions, when a particularly dense pocket of gas erupts from the nucleus. The dust and gas, being so light, is carried away by the solar wind to form the tail of the comet. It's an interesting fact that the tail of the comet always points AWAY from the Sun, so on its way out into space, the comet is actually moving tail-first.
The Coma is the fuzzy outer layer of a comet.
A comet forms a so-called coma when it passes near the Sun. A comet undergoes sublimation when it warms up therefore producing a fuzzy like appearance. The term coma comes from the Greek word "kome" which means "hair".
The tail of a comet, also known as its coma, grows as the comet gets close to the sun because of increases in temperature and force exerted by the solar wind. Since a comet's coma is usually composed of dust and vapor, the solar wind causes it to stream out away from the sun.
The "coma".
the coma is coma is a/the tail ofthe/a comet
The three main parts of a comet are the nucleus, coma, and tail. The nucleus is the head of the comet, the coma is the middle, and the tail is the end of the comet.
Halley's comet coma is 100,000 miles vs 15 miles.
Its the nebulous shock around the nucleus of the comet. Basically its the head of the comet.
During a comet's orbit, the coma and tails are the parts that come and go. The coma is the glowing, fuzzy cloud around the nucleus that develops as the comet gets closer to the Sun. The tails, consisting of ion and dust tails, form as a result of solar radiation and solar wind pushing the coma's particles away from the nucleus. Both the coma and tails diminish as the comet moves away from the Sun during its orbit.
The coma, nucleus, and the tail
A comet is made from dust and ice. It forms a tail because the ice is melted by the Sun and therefore always pointing away from it because of gravity. The comet's orbit is not circular but in the shape of an oval.
