Officials at the Luxor, which hosted "An Evening with Buzz Aldrin," said they closed the event Saturday by presenting the cake to the 80-year-old astronaut, who was the second man to walk on the moon, the Las Vegas Review-Journal reported Monday.
Luxor bosses said workers spent almost 600 hours crafting the cake and the process will be featured on an upcoming episode of TLC's "Fabulous Cakes."
Aldrin noted the electric-powered "Earth" revolving around the huge cake was traveling in the wrong direction.
"Small detail," he said. "Wrong way."
