A winter day craft with the kids |
We have a comet coming into view. It is named ISON and will be kinda neat. You can see it with some binoculars now and eventually there it will hang in the night sky. I'm psyched.
(from NASA): "Comets in hyperbolic and
parabolic orbits are typically making their first trip to the sun from the
bitterly cold and distant Oort Cloud, a roughly spherical volume of space
beginning about 3,000 times Earth’s distance from the sun and extending outward
to 50,000 times that distance or nearly one-quarter of the way to Alpha
Centauri. The Cloud is believed to hold trillions of icy comets. Think of it as
the sun’s ultimate beer cave.
