That is so fake. I mean you can tell it’s a nerf ball that’s been discolored and chewed on by a dog

It’s [wiki page](http://en.wikipedia.org/wiki/4_Vesta) has been updated with an animation showing a complete rotation of Vesta, which gives a much better sense of depth.

That’s a great link. But looking at the animation, there appears to be a long groove running along the equator (I assume it’s called the equator). Is that really there, or is it a function of the animation? And if it is there, what could cause such a long, uniform, groovy-thingy along its equator?

I’m pretty sure it’s not an artifact, it shows up in still photos. It may be the result of a geological process. Vesta is a differentiated body, it was hot enough early in it’s history for the heavier elements to sink to it’s core. The grooves could have formed as it cooled and shrank. Or it could be a result of the large impact near it’s south pole, which left an impact basin about 80% of Vesta’s width. I vaguely suspect the latter, as the grooves are roughly parallel to the the edges of the crater, but I’m no inteplanetry geologist.

I’ve read there are already over 500 pictures, and likely will be hundreds more that will get better and better as Dawn gets 10 times closer to about 100 miles from the surface over the next year. Then I read this:

“The team does not plan to post raw images online as other NASA missions have done. Instead, there will be just one picture released daily.”

Uhh… why is that again?

I guess I never realized just how big that sucker is until I saw in relation to the moon on the wiki page. Holy Moly.

I say hollow it out, spin it, live there.

I wonder how often it collides with other stuff though?

While we are at it, we could hollow out significant sections of our moon and use the excavated material to build huge artificial moons at one or more of the earth/moon libration points.

Not very often. It’s geologically dead, so unlike on Earth, once a crater is made it stays there until another one erases it.

As a Vesta virgin, it’s shy.

That’s to give them time to touch up the image to disguise the fact that it was produced on a Hollywood studio stage.

Don’t make me come down there with Vesta’s big sister, Ceres.
