The clip, said to have been filmed in the Icarus crater area, appears to show a number of pulsating bright lights moving at speed over the surface of the moon.
Launched on May 18, 1969, Apollo 10 was the fourth manned mission to the moon, and the second to orbit it.
The video was first uploaded by YouTube channel We Came in Peace, which focuses on perceived anomalies in official NASA pictures and videos of the lunar missions.
In a promotional blurb for the video, the channel said: “This video is part of series of original videos from Apollo Missions to the Moon containing footage of unidentified flying objects (UFO).”
Describing the footage, it added: “A UFO materialises above the southern skies of lunar farside.
“It initially moves away from the camera almost to horizon then decides to turn around and head straight to a crater near Icarus – located very close to the camera recording the UFO.
“Try this quick experiment: Place a piece of paper or ruler on your screen, and trace the movement of the object across the surface from its position just above the horizon to the final destination.
“Observe how absolutely straight the object’s movement path is from the horizon to Icarus crater.
“The reason why you see the object ‘skip’ across the surface at the end is likely the combination of low frame rate of the original footage and the object’s actual speed.
“Notice when the object is moving away from the camera at the start it doesn’t seem to skip as much since its position relative to the camera screen is not changing as much as when it is closing in towards the camera.”
The footage has been picked up and shown by another channel Finding UFO.
Viewers are convinced there are a number of UFOs in shot.
Elizabeth Nitzer posted in a discussion on the Finding UFO channel on YouTube: “There were actually three lights on the ground, not just two. “First one in the crater, second was in between the first and last, and the third in a crater again.
“They looked like strobe lights on a runway, meaning they were lighting up one after another.
“It’s crazy because the more one looks at it the more one sees. “At about 14 seconds there is another all the way to the left in the large crater. ”
Also in the upper right corner just as the video starts it appears as if something is ether coming up off of the moon or simply bypassing it.”
More sceptical researchers point out that, as the footage is so old and of lower quality than today, it is easy for objects to become distorted.
Anomalies in moon images and video could be dust or ice particles, which have caught the light, or just lens flares, when light refracted inside the camera appears on the lens, they say.
NASA insists it has never found any evidence of alien life during the Apollo missions or since, or anywhere else in our solar system.
