Re: How many sperical solar system objests are there?

I didn't write to this group looking for *perfect* sphere solar system
objects, or elipsoid, egg-shaped or just any solar system object. And I
didn't write to ask about dwarf planets, the article at wikipedia I had
already looked at. I was looking for a webpage that specialized in
spheroid objects in our solar system. One answer was at least a little
usefull, that was the link to the wikipedia article listing solar
system objects by mass. From this article I gather there are about 35
spheroid objects in our solar system, did I leave out any? I was hoping
to have a webpage to reference for these objects and any others I
missed as well as posting any new discoveries of new spheroid objects.

I heard in a documentary that there was about 30. Is that correct? But
I heard in another documentary that there was around 90 discovered so
far.

That number depends heavily on how much deviation from a perfect sphere
you allow before you consider the body non-spherical. Btw, the
definition of planet doesn't require these bodies to be spherical, but
to be in hydrostatic equilibrium - which allows for rotational
ellipsoids too.

No planet is a perfect sphere, I dont care if it's egg shaped.

FYI: eggs are not shaped as ellipsoids.....

Or are some going to be left out? Is there a website
that lists them all? Thanks.

There are several such lists - some probably disagree with others.
Let Google find them for you.

I've searched google and have not found any such website.

It took me less than one minute to find this:

http://en.wikipedia.org/wiki/Dwarf_planet

I think you can improve your Google skills a bit... <evil grin>
