C/2010 X1 (Elenin)

In December 2010 using CoLiTec software in Russia for the first time in 20 years was opened comet C/2010 X1 (Elenin). Discoverer of the comet is astronomer Leonid Elenin, the Institute of Applied Mathematics Keldysh. In accordance with Circular Minor Planet Center of the International Astronomical Union's new comet C/2010 X1 received the designation and name of the discoverer, Elenin. The discovery was made at the observatory ISON-NM, located in the U.S. state of New Mexico, USA. Observatory in the distance run by Russian scientists.

The next day after the discovery of comet data were confirmed by Russian, Ukrainian and Uzbek astronomers using observations at the observatory Maidanak in Uzbekistan. A day later, were obtained confirmation from the American and Japanese scientists. When you open a comet were used telescope «Centurion 18." During the opening of the comet had a magnitude of 19.5, which is about 150,000 times (= 2,51219,5-6,5) is weaker than the value of 6.5, which is able to distinguish with the naked eye. Discoverer Leonid Elenin evaluates diameter comet nucleus is 3-4 km. As of April 2011 the comet had a value of 15 (roughly the brightness of Pluto), and the diameter of the coma of the comet is estimated at 80 000 km.

At the end of August 2011 the comet nucleus collapsed, and its brightness is significantly diminished. September 10, 2011 Comet Elenin passed perihelion. October 16, 2011 the comet approached the Earth at a minimum distance - 34.9 million kilometers (0.23 AU). October 24 poster ISON-NM Observatory announced the discovery of a cloud of dust particles that are left after the destruction of the "Russian" comet. The first remains of comet Elenin discovered by amateur astronomers from Italy and the UK, and in the night from 21 to 22 October 2011 the presence and movement of the dust cloud confirmed observations at the observatory ISON-NM.

P/2011 NO1

More than six months after the opening of the first comet C/2010 X1 (Elenin) Russian astronomers using CoLiTec software opened another new comet. Comet received index P/2011 NO1. It again became a pioneer Leonid Elenin along with his colleague Igor Molotov. The comet was discovered in images taken with the help of Russian automated observatory ISON-NM (New Mexico, USA).

In observations of July 7, 2011 by Leonid Elenin observatory ISON-NM was found to receiving 100% rating NEA and sent to a confirmation page ASP ( This facility was originally recognized Neas what was published to accompany the Circular (, in which he was given the temporary designation 2011 NO1. In this case there is good reason to consider this comet. And now, a new circular IFAs MPEC 2011-O10: COMET P/2011 NO1 ( confirmed the cometary nature of the object! Another recognition of the opening of the comet was the electronic telegram number 2768 Central Bureau for Astronomical Telegrams (

This is the second comet, discovered by using CoLiTec software.

C/2012 S1 ISON

September 21, 2012 amateur astronomers Vitali Nevski (Vitebsk, Belarus, Vitebsk amateur astronomical observatory) and Artem Novichonok (Petrozavodsk, Russia, Petrozavodsk State University). Observatory project ISON (International Scientific Optical Network PulKON) was opened long-period comet near-solar C/2012 S1 (ISON). The discovery was made using a 40-cm reflector.

At the opening of the comet had a magnitude of 18 and had a coma diameter of 10 arcseconds, which corresponds to 50 thousand km away and 6.75. is most probable diameter of the nucleus of the comet is 3 km away. Subsequently, the image of the comet were found earlier pictures observatories Mount Lemmon Survey (Received December 28, 2011) and the Pan-STARRS (Received January 28, 2012), which has greatly clarified the comet's orbit. September 24 was published Circular Minor Planet Center with the first reliable orbital data of the new comet

C/2012 S1 ISON most famous comet of 2013. The researchers believe, if the comet "experienced" meeting with the Sun, it could be the Biggest comet in 2013, as well as the brightest comet of the first half of the XXI century.

P/2013 V3 (Nevski)

The next discovery Vitaly Nevsky became comet C/2013 V3 (NEVSKI) which was also opened by the software CoLiTec. On the night of 6 November 7, along with astronomer Gennady Borisov Vitaly Nevsky discovered comet C/2013 V3 (NEVSKI) during the observations at the observatory near Kislovodsk, a member of the international network of observatories ISON.

Borisov said that the two comets were discovered using telescopes made them. "It's an amazing coincidence that two comets had been opened at the telescopes, which I did. Two identical telescope and that" shot "simultaneously. Now we are with him (Nevsky) are in the table next to comets," - he said.

In 2012 Vitaly Nevsky Vitebsk discovered Comet ISON. This heavenly body, almost became a great comet of 2013, as well as the brightest comet of the first half of the XXI century.

2011 QY37 (MPEC 2011-Q51)

August 27, 2011 at the observatory ISON-NM has opened a new, near-Earth asteroid, designated 2011 QY37. This object belongs to the family of the Amur and poses no threat to Earth. Minimum distance of its orbit crossing the Earth's orbit exceeds 39 million kilometers. Asteroid turns on moderately eccentric orbit (eccentricity ~ 0.51), with a period of 3.91 years.

2012 RQ16 (MPEC 2012-S16)

September 13, 2012, the observatory ISON-Kislovodsk using the CoLiTec (CLT) was discovered asteroids near Earth, given the temporary designation 2012 RQ16. This event is dedicated to a separate electronic Circular Minor Planet Center. This is the first ASP, outdoor observatory ISON-Kislovodskbyl open approach the Earth.

2013 TB80 (MPEC 2013-T86 : 2013 TB80)

October 9, 2013 ISON-NM observatory using the CoLiTec was discovered near-Earth diameters greater than 1 kilometer. Asteroid 2013 received index TB80. Relevant data are presented on the site the Minor Planet Center of the International Astronomical Union.

2014 KH2 (MPEC 2014-K23 : 2014 KH2)

May 21th, Leonid Elenin at the ISON-NM observatory using the CoLiTec software discovered which has received designation 2014 KH2 To potentially dangerous Neas (PHA) is not enough 0.001 AU! Size - is measured while from 400 to 1000 meters.

Relatively small celestial body of the Solar System, orbiting the Sun. Asteroids are much lower on the mass and size of the planet, are irregular in shape, and have no atmosphere, although it and they can have satellites.

2011 HY52 (MPEC 2011-J02)

Asteroid 2011 HY52 was discovered during the review of the sky April 24, 2011 observers Andrushivka astronomical observatory. Preliminary orbital parameters which are close to the parameters of the orbit of the NEA.

2010 WZ71 (MPEC 2011-Q39)

Asteroids 2010 and 2011 WZ71 RC17 were discovered at the observatory ISON-NM, located in the U.S. state of New Mexico, USA. The major feature of this asteroids is that they move along the comet's orbit.

2011 RC17 (MPEC 2011-W37)

Asteroid 2011 RC17 is very interesting. The whole point of its orbit parameters. Though it is in the neighborhood of the plane of the ecliptic (inclination 11 degrees), its perihelion is less than the semimajor axis of the orbit of Jupiter and aphelion more semimajor axis of Saturn's orbit. Objects with similar orbital parameters found extremely small - only 10, and show them no more than two a year! A list of these objects with the parameters of their orbits shown in the figure.

Group of asteroids that are in the vicinity of the Lagrange points L4 and L5 of Jupiter in a 1:1 orbital resonance. These asteroids were named after characters in the Trojan War, described in the Iliad.

Jupiter's Trojan asteroids - small planets that are near the libration points of the major planets. The first such planet was discovered in 1906 at L4 point of the Sun-Jupiter system. Since all these objects began to be called in honor of the heroes of the Trojan War, and the class called Trojans.

When naming follow these rules: small planets discovered at L4 (in front of Jupiter, the orbital motion) is called with the names of the heroes of the Achaean side, and at L5 (behind Jupiter) - from the Trojan side. Only exception was Hector and Patroclus, who were called before the adoption of this rule.

There are about 1300 Trojans from the Greek side, and about 1200 - with the Trojan (June 2008). The largest of them - Hector from the Greek side (370 km) and from the Trojan Aeneas (148.2 km).

In 2001 at L4 Neptune was discovered in 2001 satellite QR322 (230 km), which is attributed to a new class of Neptune Trojans. In 2004-2007, five were discovered Neptune Trojans, yet none of them received their own name.

2013 UL10

At night from first to second November, 2013 using a CoLiTec software a Russian astronomer Leonid Elenin discovered a rare asteroid class Centaur. Object received the designation in 2013 UL10. Asteroid was detected with 0.4-m telescope remote access, set in New Mexico.

Class of small planets in the Solar System, moving between the orbits of Jupiter and Neptune. By May 2000, the family of centaurs were already about 15 members; all of them give the names of the mythical centaurs: Foul, Ness and other centaurs diameters of 100-300 km and they have a very dark surface.

Centaurus (Centaur) - a constellation in the Southern Hemisphere; not visible in our latitudes. Situated between 11h and 15h RA and between 30 ° and 60 ° south declination. Ship surrounded by constellations, Hydra, Wolf, Southern Cross, Mucha. Belongs to the ancient constellations. Stars of the Southern Cross were considered before belonging to TSENTAVR and isolated in a particular constellation in the XVII century. Greek legend linked constellation Centaurus most often with the myth of Chiron, the son of Cronus and Mills, mentor Hercules, "inventor" of the constellations, the most wise and benevolent of all Centaurus (Centaur).

"Centaurs" astronomers call a group of small bodies (ranging in size from 250 to a few tens of kilometers), orbiting between Jupiter and Neptune. Until now, the nature of these objects was unclear - some believed that it can be thrown "outside" the main asteroid belt objects, others - that is the comet. Because mixing "comet" and "asteroid" properties and they were named after the mythological creatures, "cobbled together" of men and horses.
