List of artificial objects in heliocentric orbit


Below is a list of artificial objects in heliocentric orbit, but not intended to orbit or land on any planetary or satellite body. This list does not include upper stages from robotic missions, objects in the Sun–Earth Lagrange points or objects that are escaping from the Solar System.

United States

The Federal government of the United States has placed in heliocentric orbit:
On Apollos 8 and 10–17, each S-IVB upper stage jettisoned four sections of a truncated conical adapter that supported the Apollo service module and enclosed the Apollo Lunar Module. 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.
