Asteroid VESTA

The asteroid Vesta about 516 km (almost 321 miles) in diameter is the second largest asteroid that has ever been discovered. It orbits the Sun in 3.63 years and at a speed of 69,624 km / h (19.34 km / s, over 43,000 MPH). A research probe had already digitized the asteroid and ACCENTform used this to create a replica at the 1:300,000 scale. The model weighs about 200 kg (440 lbs) and is about 1.70 m (5.6 ft) in diameter..

The surface of the asteroid Vesta consists of iron, magnesium and pyroxene rock. However, our model consists of an inner polystyrene core and a rigid outer shell coated with a modelling paste. It was pre-milled in a Styrofoam block by our five-axis machining center; then, it was coated and shaped again. To achieve an authentic surface, the model was painted and coated with sand.
