The rising Earth is about five degrees above the lunar horizon in this telephoto view taken from the Apollo 8 spacecraft near 110 degrees east longitude.
The horizon, about 570 kilometers (350 statute miles) from the spacecraft, is near the eastern limb of the moon as viewed from Earth.
Width of the view at the horizon is about 150 kilometers (95 statute miles). On Earth 240,000 statute miles away the sunset terminator crosses Africa.
The crew took the photo around 10:40 a.m. Houston time on the morning of Dec. 24, and that would make it 15:40 GMT on the same day.
The South Pole is in the white area near the left end of the terminator. North and South America are under the clouds.
