Amateur domestic astronomers Timur Kryachko and Andrey Oreshko discovered an asteroid that could collide with Earth almost through 100 years. In this case, an explosion will release energy with power 500 megatons of TNT. The list is potentially dangerous bodies a newly discovered asteroid stands next to scandalous famous Apophis.

Kryachko and Oreshko made their discovery on a managed remotely – from a Moscow apartment – a remote observatory “Elena”, located in the Chilean desert of Atacama. Observatory built by Andrey Oreshko, based on the Ritchie telescope – Chretien with a diameter of the main mirror of 0.4 m.
Timur Kryachko is well known in the astronomical world. By his name in particular, one asteroid orbiting the sun is named, and binary star system in the constellation Lizards. He is famous in Voronezh and in the astronomical world by the fact that he discovered many asteroids, comets, variable and supernovae. Expert opinion Vladimir Eletsky

– The asteroid that revolves around Timur Kryachko is named after The sun in a circular orbit, making one revolution in 5.26 years. Asteroid Kryachko was opened on December 10, 2009 using a remote access from the Tzec Maun American Observatory. It has 4 km to across. And at the time of opening it was at a distance of 317 million km from the earth. Also in honor of Kryachko and his colleague Stanislav Korotky named a variable binary star system in the constellation Lizards. The guys discovered it in 2006 with the Kazan Astronomical station.
According to Kryachko, about three months ago, he proposed to Andrei A nut to take pictures of various galaxies and nebulae in order to search for asteroids. Despite the fact that Andrew is more passionate astrophotography, he fired up the idea of a colleague and almost every night set aside her time. Unlike professionals who analyze space images using a computer program, Kryachko and Oreshko discovered a celestial object visually, from photographs starry sky. SmartNews Help
Period of revolution of the newly discovered asteroid around the Sun is 1040 days. Absolute magnitude observed object – 20.9m, that is, at least 200 m. In December 2012 circular on the discovery of the celestial body 2012 YQ1 was published Minor Planet Center, located in Smithsonian Astrophysical Observatory, which is part of Harvard-Smithsonian Center for Astrophysics. In the general directory so NASA called virtual impactors asteroid 2012 YQ1 ranked 17th place in size and 21st in terms of maximum explosion power at possible collision with the Earth.
According to preliminary calculations, discovered by Timur Kryachko and Andrey A nut a celestial object is able to approach our planet on distance from one and a half to three distances from the Earth to the Moon. IN the result may change its orbit, and then happen collision of an asteroid with the globe. According to preliminary calculations, this can happen at the beginning of 2106 or 2109. In an explosion from collisions of a celestial body with the Earth will release energy with power 500 megatons of TNT. As Kryachko specified, in the list potentially hazardous bodies the newly discovered asteroid is next to scandalous Apophis.
Asteroid 2004 MN4, better known as Apophis, discovered in 2004 year. Its diameter is 270 m, and he, according to scientists, is the most dangerous heavenly body for the Earth. By the assumption of astronomers, in April 2029, Apophis maximally will approach the Earth, at a distance of 36.8 to 37.5 thousand km, and under the impact of gravity on our planet can change its trajectory, which, in turn, will increase the chances of their collision seven years later, in 2036.
Despite the fact that the probability of the Earth meeting with one of an asteroid or comet is vanishingly small (for example, in the case of Apophis, it is estimated at 2.5 * 10-5), professional astronomers closely monitor potentially dangerous celestial bodies. More exactly the parameters of the threat emanating from 2012 YQ1, until calculated.
