Discoverer: named after Edmund Halley opening date: 1758 (first predicted perihelion) Alternate designations: comet Halley (Halley), 1P Orbital characteristics: Age: 2449400.5 (17 February 1994) Aphelion: 35.32.e. Perihelion: 0.586.e. The semi-major axis: 17, 8 and.e. The eccentricity repulsed: 0, 967 Orbital period: 75, 3 and the Inclination of the orbit to the Ecliptic plane: 162, 3 degrees Last perihelion: 9 February 1986 Next perihelion: 28 July 2061 g the Period of revolution around the Solar system: from of 74.4 to 79.2 years. The average value of 76 years. Thanks to a successful “visits” in 1986 to comet Halley spacecraft “VEGA-1 and VEGA-2” (USSR) Giotto (ESA), “Suisei” and “Sakigake” (Japan) scientists got the first pictures of the core and comprehensive information:

At the end of last week in Ulyanovsk has started an interesting project Simple science. Its initiator is the teacher of UVAU HA Leonid Podymov.
— The main purpose of my lectures is to educate. I would like to tell Ulyanovsk on the latest and most interesting achievements in modern science into simple language so that it is clear even to the unprepared listener, — says the organizer of the “Simple science”.
Leonid physicist by education, so the project is focused mainly on natural Sciences. In particular, the first lecture was devoted to astronomy — or rather, cosmic distances and scale.
— Many people know that, for example, our Solar system is big. But it is actually an ordinary person is unlikely to adequately represent these scales and distances — simply because it is not something to compare. I tried using a few simple techniques to bring clarity in such comparisons, says the teacher.
So, during the speech he invited the audience to spend with him a few thought experiments.
— Let’s imagine that our planet has shrunk to the size of a standard basketball ball whose radius 12.2 centimeters. If we reduce all other razmery accordance with a given scale, we get the following illustrative figures: the Sun will be a ball with radius 13 meters. Continue reading
At the science Museum in London opened a major exhibition “Cosmonauts: Birth of the space age”. It was to be the culmination of the cross year of Russia and great Britain, but now the British authorities have given guarantees for the return of Russian exhibits. Including artifacts that have never left the walls of private enterprises: the Soviet space ships, outfits, and archival documents. Tickets for the show sold out two months in advance.
This moment in London waiting for: when the world’s first woman astronaut will come to the machine in which it 52 years ago, spent almost three days, circling above the Earth.
“It’s such a faithful and reliable friend, by which without emotion could not be disregarded. And in the training center, when I meet him, every time I try to pet him and say “Hello!””, – says Valentina Tereshkova.
Spacecraft “Vostok-6” was never exported outside of Russia – like most of the exhibits of the exhibition dedicated to Soviet and Russian achievements in space exploration. A significant portion of what is now presented in the London Museum of science, and even Russia have seen a few. Continue reading
