El asteroide Steins a 800 Km de distancia. Imagen tomada por el sistema de imágenes OSIRIS, a bordo de la nave Rosetta, desde dos perspectivas distintas. El diámetro efectivo del asteroide es 5 Km, de acuerdo con lo predicho. En la parte superior del asteroide (como se muestra en esta imagen) se aprecia un gran cráter, de alrededor de 1,5 Km de tamaño. Para los científicos es sorprendente que el asteroide haya sobrevivido al impacto que causó el cráter.
