4 Vesta

there are tantalizing observations of localized water vapor on the surface, which may be from sublimation, ice turning directly into a gas due to the Sun's heat, or it might indicate cryovolcanoes.

Dawn also visited Vesta, which is the third largest, but second most massive asteroid known.

Vesta is around What's called an oblate spheroid, flattened a bit like a ball someone's sitting on.

The southern hemisphere got hammered by impacts long ago, leaving a huge basin there.

Several other main-belt asteroids have been visited by spacecraft, mostly via flybys.

Only a few are known, the most famous being Cruina, which can get as close as 12 or so million kilometers from us.

Oh, one more thing.

Originally, asteroids were named after female goddesses – Ceres, Vesta, Juno, and so on.

But worth having a look.

Um, there's also an asteroid, Ves- Vesta.

And Vesta's, some people classify it as an asteroid.

It's also classified as a dwarf planet.

Mm-hmm.

Lascereste alla prossima generazione di esploratori la linfa per esplorare ed estrarre nei punti che avete saltato.

Asteroidi come Cerere e Vesta, lune come Callisto e Tritone sarebbero in grado di espandere le operazioni dell'umanità oltre il Sistema Solare, dirigersi verso Plutone o Orco e nella fascia di Kuiper.

Sappiamo che il pianeta Nove è là fuori da qualche parte e voi dareste loro il potere di trovarlo.

Già, non volevate solo scalzare Musk e Bezos dalla classifica di Forbes.

And a binocular challenge.

The asteroid Vesta, at opposition yesterday, magnitude 6.5, in northern Cetus, about 5 degrees north of Theta Ceti.

And this one leans south.

At 11:00 PM, it's 49 degrees up from Sydney, around 40 to 45 from the US cities, 30 from London.

There are four other minor planets that are tenanting Aries with them.

So these include the goddess asteroids Pallas and Vesta, as well as the centaur planet Chiron, and the dwarf planet Eris.

And this week, again, everybody gets stimulated.

So today the sun in Libra opposes Vesta, and tomorrow Vesta squares Ceres in Cancer.

Ceres is another of the goddess asteroids.

I should also mention that Aries is ruled by Mars, so all of these bodies in Aries are kind of listening for guidance from Mars.

But for now, we're different.

So what does that mean? This week everybody gets stimulated, so I'm just gonna say that this is a great week for asking ourselves who we wanna be now, because the self is always under construction.

But one study found that it's not layered at all.

Vesta accounts for almost a tenth of all the mass in the asteroid belt.

Its average diameter is about 325 miles, but it's flattened and a bit stretched out.

The surface of Vesta is covered with volcanic rock.

Combined with other observations, that suggests that Vesta is layered, with a distinct core, mantle, and crust.

If so, then it formed very early in solar system history, allowing it to incorporate a lot of radioactive material.

Heat from radioactive decay partially melted it, allowing heavier materials to sink to the center and lighter ones to float to the surface.

But a study last year contradicted that.
