2010 September 9 (3)
What spectacular effects an impact of a large cosmic object can have on a planet astronomers saw last during past summer. At that time an asteroid or a comet struck Jupiter - and at times had left a scar as large as the Pacific Ocean. Read more:

Today, on 9th of September 2010, I read two articles about the same subject, asteroids, and I am now quoting from them:

Celestial bodies discovered: Asteroids narrowly miss earth

Closer than the moon: Two asteroids are supposed to fly past our planet on Wednesday and Thursday. Only on Sunday an American observatory had discovered the heavenly bodies. They miss earth - but only narrowly.

However the two asteroids were only discovered on Sunday. The Catalina Sky Survey, a telescope near Tucson (US state Arizona) had sighted the flying objects and subsequently transmitted their observations to Nasa.

The two celestial bodies come so close that already ordinary amateur telescopes should be sufficient to catch sight of them in the sky, Nasa reports.

Even the money for the search of the flying lumps is scarce.

Two large asteroids narrowly miss earth, Nasa said

Two large asteroids have narrowly avoided the earth after the objects passed - within the moon and our planet's orbit, Nasa scientists said.

The two objects were only identified at the weekend by the Nasa-funded Catalina Sky Survey near Tucson, Arizona, during a routine sky scan.

While they were visible to many amateur stargazers, space agency researchers said neither asteroid posed a risk to earth.

Experts, however, said the “double-whammy” served as a reminder of other potentially hazardous objects expected to narrowly miss Earth in coming years.

Nasa estimates that asteroids smaller than 25 meter in diameter would burn up while entering the atmosphere and cause no damage.

But what made this event so significant was that the two asteroids passed so close to Earth on the same day within hours of each other.

"I think this is Mother Nature's way of firing a shot over the bow and warning Earth-based astronomers that we have a lot of work to do," …
