THE CLASSIFICATION OF COMETS.
The comets are designated by a nomenclature, ie the name of its discoverer / s (maximum three discoverers), followed by the year of discovery and a lowercase letter indicating the number of order appearance of the comet within the year. When one considers the orbital data of the same, the year is replaced per year of perihelion passage, followed by a roman numeral indicating the order number that step.
For a comet should be visible close to the sun, this causes changes in the kite making it visible to the telescope, if weak, or if it's bright eye. Typical and morphologically
a comet consists of:
1) Nucleo.
2) Eat or hair.
3) tail or tails.
often appear devoid of comet tails, particularly those who have already taken many turns to the sun gradually losing some of its mass. In other cases show a spike or spike on the opposite side to the tail. The most widely accepted among astronomers is that the core is a dirty snowball, assuming that the nucleus of a comet is a ball of ice mixed with dust particles. The dimensions of the core can vary between 1 and 100 km.
When a comet approaches the Sun, solar radiation, evaporation of the ice cream core material. In this evaporation process arising paricular thus forming a dust cloud of gas and dust surrounding the nucleus. This cloud is the comet's coma coma diameter can reach 100,000 km.
The coma is visible through two processes: first, the comet's dust reflects sunlight, on the other hand, the molecules dissociate gas due to solar radiation and become fluorecientes, emitting light.
