Several space probes and the upper stages of their launch vehicles are leaving the Solar System, all of which were launched by NASA. Three of the probes, Voyager 1, Voyager 2, and New Horizons are still functioning and are regularly contacted by radio communication, while Pioneer 10 and Pioneer 11 are now defunct.
On June 13, 1983, the craft crossed the orbit of Neptune, and so became the first human-made object to leave the proximity of the major planets of the Solar System. The mission came to an official end on March 31, 1997, when it had reached a distance of 67 AU (10.0 billion km; 6.2 billion mi) from the Sun, though the spacecraft was still able ...

Stars are literally moving targets on the time scales current technology might reach them. An interstellar probe is a space probe that has left—or is expected to leave—the Solar System and enter interstellar space, which is typically defined as the region beyond the heliopause. It also refers to probes capable of reaching other star systems.
The spacecraft, still traveling at 64,000 km/h (40,000 mph), is the most distant human-made object from Earth and the first one to leave the Solar System. [5] Its mission has been extended and continues to this day, with the aim of investigating the boundaries of the Solar System, including the Kuiper belt, the heliosphere and interstellar space.
Communication system. [edit] The radio communication system of Voyager 1 was designed to be used up to and beyond the limits of the Solar System. It has a 3.7-metre (12 ft) diameter high-gain Cassegrain antenna to send and receive radio waves via the three Deep Space Network stations on the Earth. [ 21 ]
The term artificial objects is closely associated with made by humans or not naturally occurring items that have been sent into space. This is a list of lists of artificial objects in space found on Wikipedia. For the general concept of artificial see Artificiality. For artificial objects not in space, see Category:Inventions or List of inventions.
Below is a list of artificial objects currently 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.
