An emerald-green comet will brush the Earth Monday, followed one day later by a kissing cousin that will swerve closer to the planet than any other comet in nearly 250 years.
The first and bigger of the two comets will be visible Monday to the naked eye in the southern hemisphere, as long as city lights are far away. Stargazers in the United States will probably need only binoculars to see the bigger comet in late March. Scientists, however, are bringing out the big guns. The Hubble Space Telescope, the powerful ground-based Gemini telescopes and others will be trained on the celestial visitors, which will provide an extraordinary close-up of objects usually glimpsed only at a distance.
This is one for the record books, says Michael Kelley of the University of Maryland, whos never heard of two comets approaching close to Earth a day apart. Its a fantastic opportunity for professionals to learn more about comets, and if you have a chance to try to find them
its a fantastic chance to see part of history as it happens.

Thanks for posting.

(48,988 posts)It's not going to brush the Earth. It won't come close enough to touch it. Earth might pass through the tail and I say that only because Earth has passed through comet tails before, in recent years too.
'Science writers' seem to be more interested in sensationalism than truth sometimes.

The next thing you know they swerve and crash into things even the dinosaurs know that .

(48,988 posts)In physics, a two body orbit is easy. Three, not so much. Many bodies is very difficult. But the planets' orbits around the Sun are very stable and relatively easy to calculate because they are massive and relatively far from each other.
A comet is low mass and will swerve (alter its orbit) after approaching a planet, with the greatest effect happening from the closest distance. But they don't swerve toward the planet suddenly.
The most famous example is Comet Shoemaker Levy 9 which was captured by Jupiter and then broke up when it came too close, with the pieces colliding into Jupiter and the collision observed by astronomers.
