Figure 1: SPH simulation of the formation of the two giant impact features in Vesta’s southern hemisphere. Given the large parameter space of possible impact conditions, not every detail of Vesta’s ...

Asteroid 1999 TA10, discovered using NASA's Infrared Telescope Facility, possesses a unique mineralogical composition unlike other known Vestoids, suggesting its origin from deeper layers within the ...

For more than a decade, scientists have debated the true identity of asteroid Vesta, a 500-kilometer-wide body that sits in a gray area between asteroid and planet. Too complex to be considered a ...

A computer generated perspective of Rhea Silvia basin, which was dug out by an impact a billion years ago Vesta is the only remaining example of the original objects that came together to form the ...

Giant troughs that stretch across the asteroid Vesta may have formed after a fellow asteroid smacked into Vesta's south pole, researchers say. These findings add to evidence that, like Earth, Vesta is ...

For decades, scientists believed Vesta, one of the largest objects in our solar system's asteroid belt, wasn't just an asteroid and eventually concluded it was more like a planet with a crust, mantle ...

Scientists still aren't sure what to make of Vesta, a small body that orbits the sun. Is it an asteroid or a planet? NASA's Dawn spacecraft could settle the matter. Vesta was spotted 200 years ago and ...
