Asteroid close approaches to bodies other than earth

[MichiganMan]

I follow the JPL's impact risk page pretty much every day. But, its data is confined to potential impacts with earth only...

I'd love to find a site that would list _any_ potential impacts between bodies.... I know there was a recent close approach to Mars, and of course Shoemaker-Levy9 got me watching this stuff in the first place.... another impact of _any_ body would probably help the budgets of people searching for earth close approaches.... so surely someone is running those calculations.

anyone know if such a site exists?

Well there's 2 ways to go, but neither is good for wide scale searches like Sentry does for earth. Both are limited to individual objects.

If you go to the JPL sbdb page for an object, such as this for 2009 KK:

http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2 ... ;cad=1#orb

Down at the bottom you can click on "Show Close Approach Data" (the default is hidden)

It does show some close approaches for other objects, including the Moon, Mars, and Venus and Mercury (that's most that are relevant) when applicable. For 2009 KK, no others are currently listed other than mother earth.

The other is to go to the NEODyS page for an object such as:

http://newton.dm.unipi.it/neodys/index. ... 0&n=2009KK

And click on Close Approaches on the left.

It will also show moon, Mars, Venus Mercury as applicable. For 2009 KK, there are no others. I'll see if I can find one where other objects are listed.

The problem is, you can only search if you know the object in advance. I don't know of any site that does regular searches for CA's of asteroids with all other planetary bodies.

Here's 2007 VK184, which has a close approach to Mars:

And 2008 CK70 with Venus:
