Below is a list of artificial objects currently[update] in heliocentric orbit.
This list does not include upper stages from robotic missions (only the S-IVB upper stages from Apollo missions with astronauts are listed), objects in the Sun–Earth Lagrange points or objects that are escaping from the Solar System.
These panels are in heliocentric orbit, including those from Apollos 13–17 whose S-IVBs impacted the Moon, as the S-IVBs jettisoned them before maneuvering themselves into lunar impact trajectories.
The panels continued on lunar flyby trajectories into heliocentric orbit.
(The adapter panels on Apollo 9 were jettisoned in Earth orbit before the S-IVB burned into an Earth escape trajectory.
