Moons, planets, sun, etc. all appear to be perfectly round spheres.  Why is that?  Asteroids and other space rocks are irregular in shape.  How come they aren't spheres?

Rotation and their own gravity based on mass.

Our eyes arent that accurate. We were taught from a young age they are round. So we think thay are round. They arent.

It is a mass issue.

Smaller asteroids don't have enough mass for their gravity to eventually mold them into a spherical shape.

Mass/size.

The earth isn't perfectly round but relatively speaking it is.

Once an object gets to a certain size it's gravity creates a nice sphere esp if it's made of mainly gases.

Because the race of beings that solarformed them wanted to use the least amount of material so it shaped them like pizzas in the sky. The asteroids are the toppings.

IIRC Ceres is just over the minimum mass needed for a spherical shape to be taken.  Some bodies will have enough mass to affect their shape but not enough and end up with a more pronounced ellipsoid shape, and we do have a few of these in our solar system, I believe.

This is one of the key differences between a planet and an asteroid. They have enough mass and therefore enough gravity there their gravitational forces pull them into a sphere via the temperature and pressure created by those forces.

Asteroids/space rocks are chunks that come from broken spheres, spheres that are created and grow into perfect spheres as they consume dust/asteroids/space rocks/gasses over time, like 14.8 billion years. Asteroids and such are much younger and don’t have the ingredients available as all the perfect spheres have consumed it inside a solar system.

Yes, the Earths oblateness is 'rounder' than the standard 'in spec allowance' of a cue ball, however it is not necessarily smoother than a cue ball in areas where there are mountains and valleys.

Check out Jupiter or Saturn in a telescope, they really do not appear to be perfectly round but oval. They are markedly "Oblate" because they're not solid, so they bulge along the equator due to the spinning. All planets have that to some degree but its not as pronounced on rocky ones.

I think he said even taking into account mountains and deep see trenches it would be that smooth. If you measure the distance from the highest to lowest point you get what, 10-11 miles?  Earths diameter is just under 8000 miles so that’s .1%.

Can I ask you some irrelevant questions? Not to derail.

What exactly is an "Extreme Conservative Arch-Liberal"? Sounds... contradictory. Unless you're talking about Liberalism as defined by Reagan e.g. Classical Liberalism.

Also, regarding your sig line. I'm borderline dyslexic, and when I first took interest in politics, and kept running into based quotes by Lord Acton... I read his name as "Lord Action". Imagine my disappointment when I finally realized the "i" didn't exist.

The moons of Saturn may give the best illustration of the mass/gravitation v geometry.  Go to the Wikipedia site, scroll down to the table, and then sort on descending diameter.

https://en.wikipedia.org/wiki/Moons_of_Saturn

The best I can do is give you this photo.  In the full resolution file, Titan, the largest moon of Saturn, is about 4-9 pixels, if that.
