PIX4583518: Asteroide Vesta and other asteroides - Asteroid Vesta compared to other asteroids - Comparison of the sizes of the nine asteroides visits to date by space probes. The asteroid Vesta, with a diameter of 530 km, is the largest. This composite image shows the comparative sizes of nine asteroids. Up until now, Lutetia, with a diameter of 81 miles (130 kilometers), was the largest asteroid visited by a spacecraft, which occurred during a flyby. Vesta, which is also considered a protoplanet because it's a large body that almost became a planet, dwarfs all other small bodies in this image, with its diameter sizing up at approximately 330 miles (530 kilometers) / Bridgeman Images
