At first glance it looks like aliens are using the sun for target practice. A string of bullet-shaped streaks of light appear to be shooting straight toward the sun. These are the proverbial snowballs in Hell, plunging 300 miles per second toward a fiery end in the sun's atmosphere... The wayward comets are called sungrazers. They are a class of comet that likes to live dangerously. Sungrazers can skirt within a few thousand miles of the sun's roiling photosphere. Many are torn apart or evaporate as they streak along at a blazing 1 million miles per hour. As their orbits are perturbed, surviving sungrazers can collide with the sun on a subsequent passage. The first recognized sungrazing comet was detected during a total solar eclipse in May 1882... The most recent, comet Ikeya-Seki in 1965. Once solar observing satellites were lofted into orbit the sungrazers were easily detected. SOHO, with its coronographs, has cataloged over 1,000 sungrazers in spectacular passages... Because the sungrazers are so short-lived and many seem to follow similar orbits, they must have come from parent bodies that broke apart. In fact the majority belong to a hypothesized "mother comet" that disintegrated perhaps as long as 2000 years ago. The fragments whip around the sun as gravitational perturbations nudge the low point (perihelion) of their elliptical orbits closer to the sun.

You can’t believe every thing you see on Ytube. I would still go at night when the sun is not lit up.
How do you know its not lit up? When its night you can't see anything in the dark without a flashlight......I know I can't.
:’)
Escape velocity is higher over the poles, and, such satellites can on take photos of the Earth using a North or South Polaroid.
You want to talk about being perturbed, the news coming from DC has me all perturbed! Knocked me right out of my usual orbit.

I meant the velocity dark escapes a darkroom while processing old fashioned photos when the door is opened... ;)

Man... those things must be *really* moving in that tight of a turn around the Sun.
LOL! 2012 was a great movie! It had everything! The wife and I watched it over the weekend and thoroughly enjoyed it. The casting of Danny Glover as the President was ironically hilarious as was Woody Harrelson in the tin foil hat role.
