Man made objects leaving the solar system

Non-exhaustive list of artificial objects that are travelling faster than the Sun’s escape velocity: they are on their way to leave the solar system.

Voyager 1 and 2 left the heliosphere to coast into interstellar space in August 25, 2012 and November 5, 2018 respectively. There are no means of tracking the spent stages and mission-related debris (e.g. de-spin weights), it is probable that they will also leave the solar system.

17 artificial objects have been identified.
