Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Orbiting the Sun once every 1.8 earth-years, asteroid Eros is a diminutive 40 x 14 x 14 kilometer world of undulating horizons, craters, boulders and valleys. Its unsettling scale and bizarre shape are emphasized in this picture - a mosaic of recent images from the NEAR spacecraft processed to yield a stereo anaglyphic view. The smallest features visible here are about 30 meters across.
