Washington, Jan 04: An asteroid playing a cat-and-mouse game with Earth will pull to its closest point in almost a century on Monday before swinging away for another 95 years, Nasa said in a
statement.
Asteroid 2002 AA29 is like a mouse teasing a cat, approaching Earth first on one side and then on another, without ever making contact or actually passing our planet as the two bodies circle the Sun, the astronomers said yesterday.
At just 200 feet the tiny asteroid will get within about 6 million km on Monday.
This particular asteroid is the first ever found to orbit the Sun in nearly the same path as Earth, but never manages to pass it, the national aeronautics and space administration said.
''In some ways, the earth and this asteroid are like two race cars on a circular track,'' said Paul Chodas of Nasa's jet propulsion laboratory. ''Right now the asteroid is on a slightly slower track just outside earth's, and our planet is catching up.''
''The combined gravitational effects of the earth and sun will nudge the asteroid onto a slightly faster track just inside Earth's, and it will begin to pull ahead,'' he said.
