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
PIX4583798: Tunguska event -Artist view-3/3 - Tunguska valley - Artist view (3/3) - Artist view of the Tungouska region a few minutes after the explosion, June 30, 1908. 2000 km of forest and taiga were destroyed, blown by the shock wave of the car. Precisely what the Tunguska Event was remains a mystery. Despite the enormous scale of the explosion, there was no impact crater. Instead some 2000 sq/kms of taiga forest was flattened like matchwood and incinerated. This is the scene some minutes after the explosion. Most of the forest has been blown away, the few remaining stumps are burning and the air is full of acrid smoke. June 30 190 / Bridgeman Images
