Giant Asteroid 4183 Cuno (1959M) with an estimated diameter between 3.5 and 7.8 km approaching the Earth and will have its closest approach on 20 May.
According to Programme International Near-Earth Objects NEO, the Jet Propulsion Laboratory in California, NASA, May 20 is expected to Cuno asteroid reaches a distance of 0.14 AU from Earth a speed of 14.3 km / s.
Considering that 1 AU is the distance Earth-Sun and is 150 million km, Cone will be on 21 million km from Earth .
The asteroid was discovered on June 5, 1959 by astronomers Cuno Hoffmeister and Bloemfontein , and since then know their repeated approaches to our planet.
On March 18, 2012 recorded its closest approach to Venus at a speed of 17.5 km / s.
On December 22, 2000 approached the Earth at a distance similar to the 20 of May, ie 0.14 AU.
In 1998 we visited to 0.2 AU and on 3 February 1987 to 0.22 AU, while closer to 0.13 AU was conducted on January 14, 1976 Venus.
Cuno is the Near Earth Object (NEO its acronym in English), larger in the vicinity of our planet in recent months. It is the type of Apollo asteroids that just describes this newspaper approaches, making them be studied and monitored for potential risks.
The name Apollo -like object corresponds to the first discovered April 24, 1932 by Karl Reinmurth, according to astronomy.
Another giant will NEO on 21 June, the asteroid 308 242 (“005 GO21) of about 3 km in diameter to 0.04 AU, equivalent to 6 million miles.
In the coming days, the closer will the asteroid 2010 KK37 that just 19 to 43 meters in diameter and a speed of 10.9 km / s will reach a distance of 0.0058 AU, ie 870 000 km This equivalent to 2.3 times the distance between the Moon and Earth.
According to some astronomers to within 3.5 moon, a celestial body is most at risk of being affected by the gravity of Earth and the moon and change its trajectory. Still, it is not uncommon to pass between an asteroid and Earth.
