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.
