“Tomorrow above the Ground will fly five asteroids”

Reports of newly discovered asteroids will be coming from now… of Buryatia. A true “hunter” for the heavenly “Wanderers”, which can compete with the famous American telescope Pan-STARRS, created at the Institute of solar-terrestrial physics, Siberian branch of Russian Academy of Sciences. This wide-angle surveillance and search AZT-33ВМ, which was commissioned in the Tunkinsky district of Buryatia in the beginning of March. How are we doing with finding new asteroids in the world, any migratory guests in the sky we have to wait this week, “MK” interviewed the member of the Expert group on space threats of the Council of the Russian Academy of Sciences, fellow of the Institute of astronomy (INASAN) Sergey NARBEKOVAS.

I called Sergei Alexandrovich in order to see dangers on the next asteroid, meeting with whom we were once again promised to April 10, the minor planet Center of the International astronomical Union.

– You are expecting only one new asteroid April 10 and don’t know what’s above us flew their six (!) pieces – smiles Narenkov. – Moreover, half of them — the newest, just opened this year. Their sizes ranged from 3 to 16 meters in diameter. On Thursday 17 March over the Earth will pass five more asteroids, one of them is a freshman in sizes from 37 to 83 meters in diameter. But despite this “swarm” of meteoroids (celestial bodies with dimensions up to 30 meters) and full of asteroids (30 meters and more), they are no threat to us, because flying as a rule very far. For example, from the aforementioned asteroids, flying on 16 March, only one raced at a distance of half the distance from the Earth to the moon, that is, to 576 thousand miles away from us. The rest were much further away, at a distance of several million kilometers from our planet.

It turns out, now “population” of the famous asteroids from 10 meters to 1 kilometer is about 14 thousand. And the speed of opening new — crazy. So, according to Sergey Narenkov, Americans (the world Champions in such discoveries) every year make 1 thousand heavenly guests, flying by the planet. Share our discoveries while obscenely modest — about 1 thing a year. For them until recently answered to two telescope system ISON and “Master”. They are noticeably inferior to the U.S. Pan-STARRS. However, more recently we have hope: in Siberia in the composition of Astronomical Sayan Observatory of the Institute of solar-terrestrial physics SB RAS appeared installation. New telescope AZT-33ВМ, according to the press service of the Scientific center of SB RAS, allows you to perform a speedy overview of the geostationary orbit in the range from 40 to 160 degrees East longitude (from the Meridian to Meridian Volgograd, Petropavlovsk-Kamchatsky) and in a short time appears to register new objects, whether it be comets and asteroids, aircraft or space debris.

But it is as visible, “night” asteroids reflecting sunlight and therefore visible to us. What to do with “blind” as they are sometimes called specialists, day bodies flying from the Sunny side. Among them, too, can be potentially dangerous instances?

– We are working on this question in our Insane, says Narenkov. – Submit a suggestion to all potentially interested organizations on the establishment of a system of one or two space telescopes that scan the sky from the Ground and from low-earth orbit from the vicinity of the Lagrange point L1 of the Earth-the Sun. The Lagrangian point is located in the system of two massive bodies. In her spacecraft does not experience any influence of other forces, except gravity, and may remain stationary relative to the bodies. So the telescope, fixed at the point L 1,will detect dangerous celestial body approaching Earth from the Sun. The project is called SODA — detection System daytime asteroids, and he does not have while analogues in the world.

Help “MK”. Group of asteroids that will fly us over until March 24:

17 March — 5 asteroids, among which are two new — 2016ES155 diameter from 37 to 83 meters and 2016ER28 from 26 to 57 meters;

18 March – 1 new asteroid 2016EL157 — from 12 to 26 meters;

March 19 — 5 asteroids, among which 3 were opened in 2016: 2016EO156 from 4 to 9 meters, 2016 CY31 – from 37 to 83 meters, 2016 EN156 — from 7.5 to 17 metres ;

20 March — in the sky there will be no asteroid;

21 March — 2 asteroid;

22 March — 5 asteroids;

24 March — 3 asteroid, etc.
