Comets Comets As a comet accelerates towards the Sun, its surface temperature increases, and ices begin to sublimate into gaseous form. By the time the comet comes within about 5 AU of the Sun, sublimation has formed a noticeable atmosphere that easily escapes the comet's weak gravity.

C/2011 W3 (Lovejoy) Before perihelion, the nucleus of Comet Lovejoy had been estimated to be between 100 and 200 metres (330 and 660 ft) in diameter. Since the comet survived perihelion, it is thought that the nucleus must have been larger, perhaps up to 500 metres (1,600 ft).or other comets discovered by Terry Lovejoy, see Comet Lovejoy. Comet Lovejoy, formally designated C/2011 W3 (Lovejoy) , is a long-period comet and Kreutz Sungrazer. It was discovered in November 2011 by Australian amateur astronomer Terry Lovejoy.

What is the composition of a comet: a ball of powdered snow, solid blocks of rocks, gas or does it depend on the comet? The nucleus is the relatively solid and stable centrally located part, mostly formed of ice and gas with a small amount of dust and other solids like hydrocarbons. An interesting characteristic of the nucleus surface is the presence of dust ;

- Most are between a few and ten kilometres in size while the largest ones have an average size of about 20 km. The comet nucleus is nearly 50 % water ice and therefore the typical density may be around 1 gm/c.c. Thus an average comet has a mass that is billion times smaller than that of the earth.

- Build a Comet Comets are made of ice, gases, rock, dust and organic material. The nucleus is the solid center of the comet and contains ice, gases, dust & rocks, and organic material. The coma surrounds the nucleus and contains gas and dust. It is the ‘atmosphere’ of the comet.

Comets: Facts About The 'Dirty Snowballs' of Space We can see a number of comets with the naked eye when they pass close to the sun because their comas and tails reflect sunlight or even glow because of energy they absorb from the sun. However, most comets are too small or too faint to be seen without a telescope. Comets leave a trail of debris behind them that can lead to meteor showers on Earth. For instance, the Perseid meteor shower occurs every year between August 9 and 13 when Earth passes through the orbit of the Swift-Tuttle comet.

Comets, Asteroids, Meteorites and Impacts Comets were originally thought to come from the Oort Cloud, a spherical region that extends about 50,000 AU from the Sun where the cores of comets reside. Every once in a while, the comets are perturbed by a passing star or collision with other comets and some fall in toward the solar system.

- Comet Hale Bopp showing its two tails Courtesy of NASA. Comet Hale Bopp showing its two tails Courtesy of NASA. The ion tail T he ion tail is formed because the neutral gas, initially present in the cometary comae, is ionized by the solar radiation, giving birth to ions. These ions are susceptible to magnetic solar forces and are therefore swept out of the coma into a long, characteristic ion tail.

Comet Comet: Comet, a small body orbiting the Sun with a substantial fraction of its composition made up of volatile ices. When a comet comes close to the Sun, the ices sublimate (go directly from the solid to the gas phase) and form, along with entrained dust particles, a bright outflowing atmosphere around the comet nucleus known as a coma.

- There are two types of comet tails: dust and gas ion. A dust tail contains small, solid particles that are about the same size found in cigarette smoke. This tail forms because sunlight pushes on these small particles, gently shoving them away from the comet’s nucleus.

How Comets Work As a comet approaches the sun, it warms up. The nucleus is the main, solid part of the comet. The nucleus is usually 1 to 10 kilometers in diameter, but can be as big as 100 kilometers. It can be composed of rock.

Eclipse The region of an object's shadow during an eclipse is divided into three parts: 1  The umbra, within which the object completely covers the light source. 2  The antumbra, extending beyond the tip of the umbra, within which the object is completely in front of the light source but too small to completely cover it.

Chevrotain The single African species is consistently known as chevrotain. The names chevrotain and mouse-deer have been used interchangeably among the Asian species, though recent authorities typically have preferred chevrotain for the species in the genus Moschiola and mouse-deer for the species in the genus Tragulus.

Comets: Facts About The 'Dirty Snowballs' of Space Comet tails may spray planets, as was the case in 2013 with Comet Siding Spring and Mars. At first glance, comets and asteroids may appear very similar. The difference lies in the presence of the coma and tail. Sometimes, a comet may be misidentified as an asteroid before follow-up observations reveal the presence of either or both of these features.

The nucleus is the relatively solid and stable centrally located part, mostly formed of ice and gas with a small amount of dust and other solids like hydrocarbons. 2  The coma is a dense atmosphere surrounding the nucleus, made of a cloud of water, carbon dioxide and other neutral gases as well as dust grains. The dust tail is the most prominent part of a comet: it can be up to 10 million km long, composed of smoke-sized dust particles driven off the nucleus by escaping gases;

How Comets Work The tail is made of small (one micron) dust particles that have evaporated from the nucleus and are pushed away from the comet by the pressure of sunlight. The dust tail is the easiest part of the comet to see because it reflects sunlight and because it is long, several million kilometers (several degrees of the sky).
