这是说明:Earth and Moon
This mosaic shows images of the Earth and Moon acquired by the NEAR spacecraft 19 hours after its flyby of 23 December 1998 at 07:23 UT. The images were taken through three filters at a distance of 400,000 km from both bodies, looking up towards the south poles. The Earth is 12,756 km in diameter and the Moon's diameter is 3475 km. Antartica is clearly visible at the center of the Earth's disk, with Australia at about 1:00. The Moon is shown 5 times brighter and 10 times closer to Earth in this image.
