Asteroid Vesta: Nasa's Dawn probe reveals huge rippled asteroid is more like a small planet Ancient asteroid has iron core, like Earth Formed in similar way to our own planetVideo flyover built from data obtained by orbiting satellite since 2011 By Rob Waugh Published: 10:50 GMT, 15 May 2012 | Updated: 12:36 GMT, 15 May 2012 It's very unlikely that anyone on Earth will ever enjoy a flight over the huge asteroid Vesta, the second-biggest in the asteroid belt - but Nasa's satellite Dawn has created the next best thing. The Nasa video 'flyover' has revealed that Vesta is a 'building block' of a planet, with an iron core, like Earth, which formed in a similar way to our planet and our own moon. The video was created from Dawn's collection of images built up since it entered orbit in July 2011, including the first looks inside mysterious craters first spotted by the Hubble space telescope. Scroll down for video 'Dawn's residence at Vesta of nearly a year has made the asteroid's planet-like qualities obvious and shown us our connection to that bright orb in our night sky.
