Hmmm, 160 feet across, that ought to make a good show.

Wonder if it's worth having my Father set up the old backyard telescope.

If it comes to pass, I would think so. But I wouldn't bet on a 1 in 75 chance.

No. There is a slight chance (1 in 75) that it may hit Mars. Did you read the article?

1 in 75 is pretty good odds, astronomically speaking.

Nah.. we are safe from that one.. But.. we have a shot at getting hit later on.. SPACE.com -- Asteroid Apophis: Dealing with Earth's Future Troublemaker

Milton, it should make quite a blast, lol. The dust will fly far & wide in the lower gravity of Mars. But as to how large a scope in order to detect it..?? I would guess maybe a 4 inch refractor 8 inch SCT.

Later on they can come up with better odds, when it gets closer, as far as I know an asteroid does on wobble in it's projected pathway, so they should be able to nail down a more positive speculation if will or will not impact Mars. At least I would think they could with all our technology for measuring such things.

The "odds" would suggest a near miss, in my opinon. A way for them to have something to report for news attention.

The most interesting solar observation of late was the report that a black hole bombarded a neighboring solar system with a beam of energy, like a ray gun.
