A comet is a minor entity in the Solar System that rotates close to it in an elliptical manner and with grandiose extravagances. exist different types of kites and each of these is fundamentally composed of ice, which accelerates as it approaches the Sun and causes its evaporation.
This sublimation or evaporation is nothing more than the volatization of the materials of the comet, in other words, it would be a transformation from solid to gaseous state but without passing through the liquid state. Product of this sublimation is the emergence in the comet of the tail, among other typologies.
In 1950, a researcher specializing in comets, Fred L. Wipple, stated that comets were “dirty spheres of ice.” This great specialist was not wrong and in fact was the precedent of cometary study, therefore we can say that comets Comets They are composed essentially of water, dry ice, ammonia, iron, magnesium, methane, sodium, and silicates. These components are part of what is studied to understand the types of comets In the universe.
All these members when the comet is far beyond the Sol They are in a solid state; when they approach the sun, these compounds evaporate and volatize, as previously mentioned. The volatile components are separated from the core and are swung backward, oriented opposite the Sun, stimulated by the solar wind.
Comet classification
Comets can be classified in many ways, that is, their size, age or their size will be taken into account. orbit. Basically, we can point out that there are different types of comets.
Different types of kites according to their age
By examining the light curves discovered in comets, researchers can deduce the number of orbits they have made near the sun and categorize them into: baby kites (<5), young (<30), medium comets (<70), old (<100), and Methuselah comets (>100). On the other hand, they also estimated and categorized as follows:
1. Jupiter Family Comets
These comets are those that have a short period, whose orbits have spherical stages of less than 20 years as well as ordinary girls. orbitalsTo better understand this phenomenon, it may be useful to consult information on orbits in space.
2. Halley-class comets
These are comets with cycles between 20 and 200 years, which would be of medium degree.
3. Long time kites
With times of more than 200 years. These last comets come from the Oort cloud, the two initial ones from the belt transneptunian.
Different types of kites according to their size
Observing the dimension of these essences celestial, can be classified as the one indicated below.
1. Dwarf Kite
They are the ones that have a distance between 0 – 1,5 km.
2. Little Kite
They have a size waves between 1,5 – 3 km.
3. Medium Kite
present a distance 3-6km
4. Big Kite
It goes from 6 to 10 km.
5. Giant Kite
They are those who enjoy a journey between 10-50 km.
6. Comet “Goliath”
In this case it is represented as follows: >50 Km. For example, Comet Encke (4 km) is a medium one and the Halley (12 km) can be classified as a giant comet. Comets are a real distraction for those interested in astronomy and astrophysics, as their exposure can cover everything from the structure of the Oort cloud to the alignment of the Solar System.
Comets according to their orbit
Another way to designate and classify different types of comets is through their orbit. In this sense, two different types of comets are distinguished by the celestial trajectory they design: long-period comets, which originate from further away and are born in the Oort Cloud; and short-period comets, which descend from the Kuiper belt.
name of comets
The astronomers They have outlined a specific nomenclature for comets, using the letters P (Periodic) for those with repeating orbits and C or D for non-periodic ones. This style is based on the comet's periodicity: if its orbit is shorter than 200 Earth years, it is considered periodic.
examples of comets
1. Halley's Comet
Possibly the most famous comet that exists, it has an orbital phase of approximately 79 years and is one of the most radiant and most treated of those that come from the Oort Cloud. It is, in fact, the only short-phase comet visible to the naked eye from the EarthIt has been noted since ancient times, and its arrival sealed the beginning or end of eras, the coming of liberators or the fall of empires, according to personal exegesis. To learn more about its brilliance and characteristics, you can consult why comets shine.
2. 19P/Borrelly
This is the name given to a periodic comet revealed by Alphonse Borrelly in 1904 and whose orbital cycle is 6,8 years. In 2001 it was visited by the probe heavenly Deep Space 1, which was able to acquire photographs and many advantageous verified data.
3. Great Comet of 1577
Official pseudonym C/1577 V1, this comet passed by the Earth in the year 1577 and was examined by many European researchers, such as the Danish Tycho Brahe. This event infiltrated the forced ideas to finalize that there are objects crossing beyond the atmosphere of the land.
4. Comet Coggia
Its official nickname is C/1874 H1 and it is a non-periodic comet first noticed in 1874 by the scientific French Jerome Eugene Coggia. This comet returned to walk around the Earth between the years 1877 and 1882, time in which it was divided and decomposed in space.
5. Comet Hale-Bopp
Similarly known as The Great Cometa of 1997 or C/1995 O1, is perhaps one of the most noted comets during the 1995th century and one of the most radiant ever distinguished. It was revealed at the same time by Alan Hale and Thomas Bopp in XNUMX and produced a veritable planetary upheaval, when a celestial craft was witnessed following close behind. Admirers of the Heaven's Gate UFO devotion in the US then performed a famous mass suicide.
6. The Great Comet of 1811
This comet, official alias C/1811 F1, could be examined for 260 perpetual days and with the naked eye, given its panorama and its dimension of 40 km in diameter. It is appreciated that its cycle orbital is 3065 years old, so we will not see it again in these dwellings for a long time.
7. 67P/ Churyumov-Gerasimenko
Expressed in 1969 by Klim Ivánovich Churyumov due to the studies of the scientist Svetlana Gerasimenko, it has an orbital cycle of 6,6 years and was, in March 2004, the destination of the European Rosetta cosmic task. This celestial probe was able to get close enough to the abnormal body of the comet to acquire photographs and measure its magnetic terrain. The derivations were key in breaking down previously accepted theories about the origin of water on our planet, which links to the origin of water.
8. 3D/ Biel
Seen in 1772 and 1805, it was not until 1826 that the German scientist Wilhelm von Biela was able to deduce its orbit. However, its passage through the earthly orbit was impressive for many localities that saw some apocalyptic news in it, in 1845 it was warned divided into two and in 1877, when it had to cross again, it did not. Instead, a meteor shower of almost 6 hours was discovered in the area of Andromeda.
9. Shoemaker-Levy 9
Another of the different types of comets is the Shoemaker-Levy 9, manifested in 1993 and properly cited as D/1993 F2, it was very significant in the year of 1994, when it was flung towards Jupiter and crashed inside. The event caused deep attraction in the media and world astral science, as it was the first visible bombing of a space organism in the atmosphere of a planet.
