An asteroid is coming, and scientists are excited. Fear not, Earth is safe [View all]

(CNN) -- Look out for Asteroid 2012 DA14.

It is heading toward Earth at 17,450 miles per hour, according to NASA, and the tug of our planet's gravitational field will cause it to accelerate when it gets here.

But it's not going to strike us, when it passes by on February 15. NASA is adamant about this.

"Its orbit is very well-known," said Dr. Don Yeomans, NASA specialist for near-Earth objects. "We know exactly where it's going to go, and it cannot hit the Earth."

But it will give the Blue Planet the closest shave by any object its size in known history, Yeomans said. Gravity will cause it to fly a curved path, tugging it closer to Earth's surface than most GPS or television satellites.
















The Number: Hazardous asteroids
While the asteroid is moving at a good clip, space rockets have to accelerate to an even higher speed to escape Earth's gravity and make it into space. Though 2012 DA14 will be flying more slowly, its trajectory will keep it from falling to Earth.
