Main article: List of artificial objects in heliocentric orbit

The first artificial object to orbit the sun is the Luna 1. The spacecraft was originally designed to intentionally crash into the moon, and, after missing its target in 1959, inadvertently became the first human-made object to ever leave Earth's orbit and circle around the Sun, where it remained to this day.
