> After LM separation, the S-IVB was intended to fly into solar orbit. The S-IVB auxiliary propulsion system was fired, and the remaining propellants vented to slow it down to fly past the Moon's trailing edge (the Apollo spacecraft always approached the Moon's leading edge).
> The Moon's gravity would then slingshot the stage into solar orbit. However, a small error in the state vector in the Saturn's guidance system caused the S-IVB to fly past the Moon at too high an altitude to achieve Earth escape velocity. It remained in a semi-stable Earth orbit after passing the Moon on November 18, 1969.
> It finally escaped Earth orbit in 1971 but was briefly recaptured in Earth orbit 31 years later. It was discovered by amateur astronomer Bill Yeung who gave it the temporary designation J002E3 before it was determined to be an artificial object.
