NASA tries to quell fears of Comet strike for May 25th

Chunks of a comet currently splitting into pieces in the night sky will not strike the Earth next month, nor cause mass extinctions or giant tsunamis NASA officials said Thursday.

The announcement, NASA hopes, will squash rumors that a fragment of the crumbling Comet 73P/Schwassmann-Wachmann 3 (SW 3) will slam into Earth just before Memorial Day.

"There are some Internet stories going around that there's going to be an impact on May 25," NASA spokesperson Grey Hautaluoma, told SPACE.com. "We just want to get the facts out."

Astronomers have been observing 73P/Schwassmann-Wachmann 3, a comet that circles the Sun every 5.4 years, for more than 75 years and are confident that any of the icy object's fragments will remain at least a distant 5.5 million miles (8.8 million kilometers) from Earth - more than 20 times the distance to the Moon - at closest approach between May 12 and May 28.
