Astronomers Discovered the Asteroid with the Earth Like Orbit

Asteroid 2010 SO16, discovered earlier telescope WISE, moves almost exactly on the Earth’s orbit and may be a “brother” of the Earth – one of a group of protoplanetary celestial bodies, from which it emerged, according to astronomers from the Northern Ireland Observatory Armag. Most asteroids near Earth (NEA), have very elongated orbits, SO16 but has a nearly circular orbit, and therefore can not converge to any other planet except Earth.Astronomers have decided to establish how stable the orbit of this asteroid, and how long it takes her.

NASA Destroyed Comet Hunter Satellite

NASA deliberately deactivated their satellite Stardust, burning his last reserves of fuel in the experiment to help engineers planning future missions.Stardust was launched in 1999 and in 2004 became the first and so far only satellite to collect samples of comet dust during a flight to the comet Wild 2. Samples have landed on Earth in a capsule in 2006. But Stardust continued its flight. Since all of its systems were normal, NASA has decided to convert it by adjusting its orbit to the intersection with the comet Tempel 1 on Feb. 14 this year.

Days on Earth Shortened after Earthquake in Japan

How the Japan Earthquake Shortened Days on Earth. A new analysis of the 8.9-magnitude earthquake in Japan has found that the intense temblor has accelerated Earth’s spin, shortening the length of the 24-hour day by 1.8 microseconds, according to geophysicist Richard Gross at NASA’s Jet Propulsion Laboratory in Pasadena, Calif.Gross refined his estimates of the Japan quake’s impact – which previously suggested a 1.6-microsecond shortening of the day – based on new data on how much the fault that triggered the earthquake slipped to redistribute the planet’s mass.
