Así será el paso del asteroide 2012 DA14 cerca del planeta Tierra

A tan solo pocas horas para que el asteroide 2012 DA14 pase rozando la Tierra, astrónomos y curiosos de todo el planeta preparan sus instrumentos para no perderse ni un detalle del acontecimiento. Ahora, la empresa de software espacial Analytical Graphics Inc. (AGI) ha elaborado este detallado vídeo con todo lo que se conoce sobre este “invitado” espacial..



El punto de máximo acercamiento del asteroide se producirá este viernes a las 20:24 (hora de España), pasando a penas a 27.630 kilómetros de distancia de la superficie terrestre.
En este video, los analistas de AGI pretenden mostrar cómo se vería la aproximación desde la perspectiva del asteroide.
La recreación también muestra cómo 2012 DA14 pasa “por debajo” de la constelación de satélites geoestacionarios y añade el efecto perturbador que las gravedades combinadas de la Tierra y la Luna ejercerán sobre su órbita.

Video: Tiny Asteroid 2012 KT42 Crossing The Sky
On February 15, a 45-meter wide asteroid known as "2012 DA14" will pass within 20,000 miles of Earth, which is approximately 1/12th of the way to the Moon and well within range of many Earth-orbiting satellites. While scientists don't anticipate a collision with Earth, it could make for some fantastic skywatching for space geeks in certain parts of the world.

To capture the event, AGI aerospace engineers have used our Systems Tool Kit(STK) software to create an animation showing:
-2012 DA14's deep space trajectory as it approaches Earth
-The pass by Earth below the GEO Belt and crossing the equatorial plane from South to North
-A closeup of the asteroid during its closest approach
-A highlighted portion of Earth orbit that it is expected to pass through

An interactive scenario is available here:

and can be viewed with the free STK product available here:

You can view it in 3D, add satellites from the database, fuse it with user trajectories and/or calculate close approaches to orbiting satellites with STK Conjunction Analysis Tools(CAT) available here: http://www.agi.com/stk-conjunction-an....

AGI engineers have also created a demo using Cesium, a WebGL virtual globe and map engine. Click here to run the demo: http://cesium.agi.com/2012DA14/
Note, Cesium doesn't work with Internet Explorer. We recommend installing free Google Chrome.
