Photograph of Saturn and its satellites Tethys (outer top left), Enceladus (inner top left) and Mimas (bottom right). It was taken by Voyager 1 on October 30, 1980 from a distance of 18 million kilometres (11 million miles). The soft, velvety appearance of the low-contrast banded structure and increased reflection of blue light near the perimeter of the Saturn disk are due to scattering by a haze layer above the planet's cloud deck. Features larger than 350 kilometres (220 miles) are visible . The projected width of the rings at the centre of the disc is 10,000 kilometers (6,000 miles), which provides a scale for estimating feature sizes on the image.
