You may have seen this photo before. Taken in 1968, by an Apollo 8 astronaut, it is commonly referred to as Earthrise.
From the moons surface, the Earth doesnt technically rise, since the same side of the moon always faces Earth. The view of Earth would not substantially change from any point on the moons surface. This shot, and others like it, were taken from orbit the rise comes from the trajectory of the spacecraft.
So, what happens when you stitch a whole series of Earthrise photos together?
Reddit user Notbrit produced this incredibly smooth animation from a collection of sequential shots. The motion, again, is caused by the changing perspective of the orbiter, not rotation of the Moon. But still: incredible.

(80,708 posts)"1968" - which deals, particularly, with Apollo 8 - is one of the best.

(5,719 posts)The lunar orbiter (CSM) started in an elliptical orbit and then moved into a circular parking orbit 69 miles above the surface. It took 2 hours to do one rotation of the moon. I wonder if the CSM commander would get bored when the lunar module detached and he was completely alone?

(356 posts)always wondered what it must be like to see the earth from space. We're so used to watching the small moon but I bet it must be breathtaking. I'm jealous of those who have experienced it. Wow!
