Comets of the Solar system
A comet is a heavenly body of small dimensions, which consist of ice with flecks of dust and stone fragments. When approaching the sun the ice begins to evaporate, because the comet remains a tail, sometimes stretching for millions of miles. The tail of a comet consists of dust and gas.
The comet’s orbit
Generally, the orbit of most of the comet is an ellipse. However, rarely there are also circular and hyperbolic trajectories that move ice bodies in outer space.
Comets passing through the Solar system
Through the Solar system a lot of comets. Stop the most famous space Wanderers.
Comet rentals-Roland was first discovered by astronomers in 1957.
Halley’s comet passes near our planet in times of 75.5 years. Named after British astronomer Edmund Halley. The first mention of this celestial body are found in ancient Chinese texts. Perhaps the most famous comet in the history of civilization.
Comet Donati was opened in 1858 by the Italian astronomer Donati.
Comet ikeya-Seki was a Japanese spotted by Amateur astronomers in 1965. Different brightness.
Comet Lexile was obnaruzhena 1770 by the French astronomer Charles Messier.

Comet Hale-BOPP was visible in 1997 with the naked eye.
Hyakutake the comet was observed by scientists in 1996 at a small distance from the Earth.

Experienced astronomers on the question of what the comet in the entire history
observations closest to the Earth, most likely will answer it
Comet Schwassmann-Wachmann was first noted by the German astronomers in 1927.
“Young” comets have a bluish tint. This is due to the large amount of ice. With the rotation of the comet around the sun, the ice melts, and the comet is a yellowish tint.
Most of the crashes comets from the Kuiper belt, representing a collection of frozen bodies that are close to Neptune.
If the comet’s tail blue hue, and is turned from the Sun is a Testament to the fact that it consists of gases. If the tail is yellowish and turned to the Sun, it is a lot of dust and other impurities are attracted to the sun.
The study of comets
Scientists get information about comets visually through telescopes. However, in the near future (2014) year of the scheduled launch of the spacecraft of ESA’s “Rosetta” for exploring one of the comets. It is expected that the device will stay near the comet for a long time, accompanying space for wanderer in its path around the Sun.
The solar system – Mystery, puzzles, facts
The solar system consists of nine planets and the asteroid belt. Comets
one of the major mysteries of the Solar system . As and when formed.
Note that earlier NASA launched the spacecraft “Deep Impact” collision with one of the comets of the Solar system. Currently the machine is in good condition and is used by NASA to study the icy celestial bodies.
Comets and asteroids
But the most fantastic spectacle unfolded in the Solar system
16-22 July 1994, when comet shoemaker-levy broke up into part I.
