Well, you can have a look at the Neodys pages, where occasionally some close encounter with planets and/or Ceres and Vesta are reported. Very likely it is a...

I am truly dismayed at the type of attacks occurring here. There was no mention of something wrong with privately held telescope ownership and in fact it...
I'm rather dismayed by the fact in the recent "accuracy" thread that comments made in jest about using a telescope instead of continuing the thread, or the...
When I was young we were taught about 'significant places' in numbers. In this computer age, where you can program a computer to generate an answer to any...

I have a feeling I should know the answer to this, but don't: Who keeps a list, "officially" or "unofficially", of binary asteroids? I ask because my colleague...

Amazing! The problem is the deeper you go the less help you get for followup. At or around the next opposition most of these will be too faint for garanteed...
I just retro-updated my calendar. It previously only went back to Jan. 2003. The entries before that were on the Yahoo Group calendar of the Amarillo Astronomy...
Just to extend this inquiry slightly: does anyone maintain a list of orbital elements for these (admittedly, they'd be "something resembling elements" for...
Yes - I'm also VERY interested in having even the most approximate orbits. While the various links given in the chain give _some_ orbital parameters, none of...

Matt, You are right. It did matter where one hunt when going this deep, by hunting mainly east of opposition, the newly discovered asteroids will become...
