Asteroid news: NASA tracks three space rocks making near-Earth approach TODAY

Why is NASA tracking asteroids?

Near-Earth Objects include comets and asteroids nudged by nearby planets’ gravitational pull into orbits causing them to enter Earth’s cosmic neighbourhood.

Most rocky asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter.

NASA said in a statement: “The scientific interest in comets and asteroids is due largely to their status as the relatively unchanged remnant debris from the solar system formation process some 4.6 billion years ago.

“The giant outer planets (Jupiter, Saturn, Uranus, and Neptune) formed from an agglomeration of billions of comets and the left over bits and pieces from this formation process are the comets we see today.
