is there any information about the size of the sun, is it perfectly oval, spherical, totally round or hexogone?

The Sun is a near-perfect sphere, with an oblateness estimated at about 9 millionths, which means the polar diameter differs from the equatorial by about 10 km.

joe: "Is the sun hexagone?"
Tom: "sure, if your eyes saw round things six-sided"
joe: "Darn! so that is why I failed my geometry test"

hmmm
:lol: @ the "eyes" ;)

The sun is round- sphere.
When objects get to a centain mass they become sphere's.

As the page that Radiation Specialist links to explains, there is a slight bulge at the equator. But in the case of the sun it is relatively small because the sun rotates fairly slowly.

In the case of Jupiter, which rotates rapidly, the bulge is noticeable to the eye.

Oppps :o forgot about that :o:o

The earth has a slight bulge too...

I thought I heard somewhere it was more pear-shaped, with an extra bulge in the southern hemisphere. That would make the volcano Aconcagua (6959 m from sea level) in the Andes the farthest point on the surface from the center of the earth, rather than Everest (8844 m from sea level).

I'm probably wrong, though :P

The summit of Chimborazo (6267m), Ecuador, is the farthest point from the centre of the Earth, by virtue of being closer to the equator than Everest.
There's a general lumpiness to the shape of the Earth on a smaller scale than the equatorial bulge, so it's sometimes described as being pear-shaped.

I thought it was something like that. I couldn't remember which south american mountain it was, so I just picked the tallest. Silly me!
