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. Spacecraft that are still in their systemic context, i.e. still operational, are highlighted in orange.
