On the other hand, what if "the comet was shattered by a hit from a small interplanetary boulder?" A violent collision would produce faster-moving debris that could reach Earth in 2006.
Wiegert expects to see nothing, but he encourages sky watchers to be alert.

Paul Wiegert is an astronomer at the University of Western Ontario.

On the plus side, the difference means, "we just didn't 'forget to take the lens cap off,'" said Queens University astrophysicist Paul Wiegert in an e-mail.
The study should help reduce fears of falling comets, but just last week, an asteroid the size of a soccer field blew by the Earth at a distance scientists described as "a close shave." It would have devastated any city but no one saw it coming.
Wiegert said scientists estimate the threat posed by comets is only about 25 per cent, while the chance of a close call from asteroids is roughly 75 per cent.

"Many near-Earth asteroids move on orbits crossing that of the Earth, but none has previously been identified as a dynamical companion of the Earth," astronomer Paul Wiegert of Canada's York University reports in the current issue of the journal Nature.
Wiegert and two Finnish astronomers collaborated to plot the bizarre celestial dance that actually prevents the asteroid, as it follows a path shaped roughly like a kidney bean, from colliding with the Earth as the two objects circle the sun together.
As it draws near the Earth, gravity slightly increases the asteroid's orbital period from slightly less than a year to slightly greater, pushing the asteroid into a path that sends it spiraling forward along the orbit of the Earth, so that a collision is avoided.

The astronomers who studied the asteroid's orbit, officially named Asteroid 3753, were Dr. Paul Wiegert and Dr.Kim Innanen from Toronto's York University and Dr. Seppo Mikkola from Turku University in Finland.
When Wiegert first stumbled on the rare orbit it was a complete surprise.
He thought he had made an error in the computer calculations and repeated the process several times before he was convinced of its authenticity.

 Cometary String Of Pearls To Swing Past Earth In May
Because of the uncertainty, it is possible 73P could produce a meteor shower as it passes by.
Regarding the breakup, Wiegert said the most likely explanation is thermal stress.
Wiegert said he expects to see nothing, but it would not be the first time a dying comet produced a meteor shower.

It was officially discovered on October 10, 1986 by D. Waldron, working with R. McNaught, M. Hartley and M. Hawkins at Siding Spring Observatory, Coonabarabran, Australia.
However, its unusual orbit was not determined until 1997 by Paul Wiegert[?] and Kimmo Innanen[?], working at York University in Canada, and Seppo Mikkola[?], working at the University of Turku[?] in Finland.

 Near-Earth Asteroid 3753 Cruithne
This asteroid shares the Earth's orbit, its motion "choreographed" in such a way as to remain stable and avoid colliding with our planet.
This relationship was revealed in a paper by Paul Wiegert, Kim Innanen and Seppo Mikkola, and published in the British-based science journal Nature on June 12, 1997.

 New Scientist Breaking News - Asteroid follows Earth around orbit
But it will not be a genuine moon because its orbit will still be controlled by the Sun.
Paul Wiegert of Queen's University, Ontario, Canada, says: "Both the Earth and the asteroid still both go around the Sun, but the relative looping motion of the asteroid in some ways resembles a satellite orbit, with an apparent period of one year."
Another asteroid, 3753 Cruithne was found to move around the Earth in a similar horseshoe orbit in 1997.

Recent calculations (Wiegert, Innanen and Mikkola, 2000, Icarus 145, 33-43) indicate stability of objects in ETA orbits over a million year timescale and that their on-sky density would be greatest roughly five degrees sunward of the L4 position.

As I thought about this I visualized a model, or demonstration, accessible home that could be used by everyone in the community to learn about accessible design and construction, and to actually see examples of what is available.

With that encouragement Paul, Joe, and I took on a project to build a model home in Wausau for display purposes and for use as a teaching laboratory for NTC students and local contractors.

York University astronomers, working with a Finnish colleague, have discovered a mysterious "companion" to the Earth, shedding more light on the origins of our solar system.
Discovered in 1986, Asteroid 3753 measures between one and ten kilometers in diameter, and has an inclined and eccentric path that crosses the orbits of both Earth and Venus.
Although discovered 11 years ago, no one had tracked its path thoroughly enough to detect its rare "horseshoe" orbit.
