How Religion Drives Science and Why it Matters
Dr. Hunter, you may appreciate this lecture on Euler. I really enjoyed watching it.An Evening with Leonhard Euler – videohttp://www.youtube.com/watch?v=h-DV26x6n_Q
130 miles in diameter, so not very massive. I wonder what the orbital velocity is and how far above the asteroid the spacecraft is orbiting.
9,900 miles, try planetary society blog for good info
velikovsky are you into amateur astronomy?
Just a hobby, it is endlessly interesting and awe inspiring.
330 miles in diameter is a pretty big chunk of rock. Imagine what it would do if it hit us going at 50,000 mph.
You might find this interesting..http://simulator.down2earth.eu/Also, see the Tunguska event, which is estimated to be the result of 60 meter comet. http://en.wikipedia.org/wiki/Tunguska_event
Thanks, Scott, that's a really neat simulator. As an aside, one thing I remember was a scientist commenting on the CGI animations of such impacts in movies like Deep Impact and Armageddon. He thought they vastly underestimated both the brightness of such objects and the immense amount of heat they would radiate.
Game over, the Chicxulub,which rubbed out the dinos, is estimated around 10 miles
"Just a hobby, it is endlessly interesting and awe inspiring."Good for you. It's very frustrating to watch the sky from light polluted city.

It's very frustrating to watch the sky from light polluted city.This ^^^When I first moved into my current home some 30 years ago I used to be able to see the Milky Way from my backyard. Spent many nights up into the wee hours visually gazing with my old 10" Dobsonian. Sadly, urban creep and the subsequent light pollution has all but killed my amateur astronomy hobby. :(
10" Dobsonian - nice.Royal Astronomical Society of Canada is promoting Light Pollution Abatement. They are trying to convince regional governments to slowly replace usual "cobra" light fixtures which illuminate the sky unnecessarily. I see something positive happening lately. New installations are mostly properly shaded fixtures with sharp cut off above horizontal plane. Looks like local governments are listening.Any nebulous objects are impossible from the city but Moon, planets, open clusters, asterisms , binary or other multi star systems, variable stars are still OK. At least where I live.
If you are willing to sleep under the stars,two to three hours away is dark sky,if you go 7 hrs or so the Ft Davis / McDonald Observatory is an 11
