Simple observation tells us that a an object sent on a moon flyby will enter solar orbit. The escape velocity of the earth is 11km/s but the escape velocity of the solar system is like four times that.  Therefore, unless we accidentally accelarate the probe to over 40km/s, it will certainly remain in solar orbit.

:Randall may have been imagining an earth orbit, which would explain being able to see it. 'Co-orbiting the Sun' is just the pedantic idea that the earth and moon orbit a common centre of mass.[[Special:Contributions/141.101.77.212|141.101.77.212]] 16:12, 3 November 2018 (UTC)
  
 
There are only four comics listed in the JFK category and in two of them, the mention is incidental. I don't see any evidence that Randall "does not like that JFK", nor would I expect to.
