These are known as interstellar probes, a space probe that has left, or is expected to leave the solar system and enter interstellar space. There are currently five out there; Pioneer 10 (now inactive), Pioneer 11 (inactive), Voyager 1 (functional), Voyager 2 (functional) and New Horizons (functional - currently on its way to Pluto).
There are, or have been various other interstellar probes in the pipeline, including; `TAU mission` (a probe designed to reach a thousand astronomical units in 50 years), the `Innovative Interstellar Explorer` and the `Realistic Interstellar Explorer & Interstellar Explorer`.
The two Voyager space probes are robotic spacecraft launched in 1977 as the first spacecraft to examine the outer planets. Both are still operating, having passed the orbits of the outer planets, and drifting toward the boundary of the solar system.
Voyager II is the first successful space probe that reached the outer planets or Jovian Planets. It is in the rule of probes that they should not reach the outer planets because it is too far and their probes might malfunction. But this Voyager II probe had a successful flight to the outer planets.
The four outer planets but it depends what you mean by the outer solar system. If the boundary is set at 4 AU, you have Jupiter, Saturn, Uranus and Neptune.

No, the Voyager mission involved two space probes, Voyager 1 and Voyager 2, which were unmanned spacecraft launched by NASA in 1977 to explore the outer planets of our solar system. The probes have continued to travel beyond the solar system into interstellar space.
The four outer (gas giant) planets are; Jupiter, Saturn, Uranus and Neptune.
The Voyager probes were launched by NASA, the space agency of the United States. They were launched in the late 1970s to explore the outer planets of our solar system.
The Outer planets are often referred to as Gaseous planets. The others are the "inner planets" or rocky planets.
The outer (major) planets of our solar system are the 4 gas giants:JupiterSaturnUranusNeptuneFurthermore, 4 out of the 5 dwarf planets are also in the outer solar system, beyond the orbit of neptune:PlutoHaumeaMakemakeEris
inner planets are mercury Venus earth and mars while outer planets are Jupiter Saturn Uranus Neptune
Two examples of probes are spacecraft like Voyager or New Horizons, which are sent to explore outer planets and the edges of our solar system, and scientific instruments like thermometers or pH meters used to measure temperature or acidity levels in various substances.
the four outer planets of this solar system are as followed. jupiter, satern, uranus, and neptune.
