Two other space stations that have orbited Earth in the past are Mir, which was operated by the Soviet Union and later Russia, and Skylab, which was operated by NASA. Both stations played important roles in advancing human space exploration.
There really isn't a definition of the Apollo missions so much as a purpose for the Apollo Program as well as a purpose for each mission that supported the goal of the Apollo Program. The Apollo Program was a program that ran from 1963-1972 with the purpose of safely placing a man on the moon as well as safely bringing him back to Earth. Of all the missions, two orbited the Earth, two orbited the moon, one (Apollo 13) was supposed to land on the moon but malfunctioned, slungshot around the moon and safely returned to earth leaving six missions that actually landed on the moon and returned safely to Earth.
The Apollo 11 mission, the first lunar landing mission, was crewed by Neil Armstrong, Buzz Aldrin, and Michael Collins. Neil Armstrong and Buzz Aldrin became the first two humans to walk on the moon. Michael Collins orbited the moon in the command module while the other two astronauts descended to the lunar surface.
As of October 2023, only two astronauts have orbited the Moon twice: Frank Borman and Jim Lovell. Both men were part of the Apollo program, with Borman serving as commander of Apollo 8, the first crewed mission to orbit the Moon, and Lovell being part of both Apollo 8 and Apollo 13 missions.
Mercury . . . carried one astronaut at a time, into low earth orbit. Gemini . . . carried two astronauts at a time, into low earth orbit. Apollo . . . carried three astronauts at a time, into low earth orbit, trans-lunar injection, lunar orbit, and two of them to a lunar landing.

Michael Collins piloted the Command Module which orbited the moon and Edwin "Buzz" Aldrin piloted the Lunar Module which landed on the surface of the moon.
If you mean on the lunar surface, then it is because he was not one of the two astronauts that descended to the moon. Collins orbited on board the Columbia and there is a picture of him from this time.

The two things brought back to earth by Apollo 11 were moon stones and moon dust.
The command service module , orbited the moon, in Apollo 11 it was Michael Collins, who did experiments, while the lunar module landed on the moon. With the two astronauts.

In the LEM (Lunar Excursion Module) designed and built by Grumman. the LEM was designed to carry 2 astronauts was jetisoned into space prior to re-entry to earth´s atmosphere.
Which two astronauts are you asking about. Supplying their names would help us answer you.
Astronauts can ride horses at night because their experience in space has no impact on their ability to ride horses on Earth. The two activities are unrelated, and astronauts can participate in regular activities like horseback riding when they are back on Earth.
Ptolemy and Copernicus' ideas about the universe are different from each other in the sense that Ptolemy thought that every celestial object as well as the sun and the moon orbited the Earth whereas Copernicus had the thought that all planets orbited the Sun, while the Moon orbited the Earth.
