Voyager 2 is a space probe launched by NASA on August 20, 1977, as a part of the Voyager program. It was launched on a trajectory towards the gas giants (Jupiter and Saturn) and enabled further encounters with the ice giants (Uranus and Neptune).

2024年11月2日 · Voyager 2 is the only spacecraft to visit Uranus and Neptune. The probe is now in interstellar space, the region outside the heliopause, or the bubble of energetic particles and magnetic fields from the Sun.

旅行者2号（英語： Voyager 2 ）是一艘於1977年8月20日發射的美國太空總署無人星際太空船，截至2020年依然正常運作，是有史以來運作時間最久的太空探測器。

2024年3月10日 · Both Voyager 1 and Voyager 2 have reached interstellar space and each continue their unique journey deeper into the cosmos. This near real-time 3D data visualization uses actual spacecraft and planet positions to show the location of both Voyager 1 and 2 and many other spacecraft exploring our galactic neighborhood.

1977年8月20日 · During its travels through the outer solar system, Voyager 2 visited all four gas giant planets, and also discovered and photographed many of the planets' moons. The spacecraft's flyby of Neptune in 1989 set it on a course below the elliptic plane that eventually took it to interstellar space on November 5, 2018.

2025年3月5日 · Voyager 1 and Voyager 2 remain the most distant human-made objects ever built. Voyager 1 is more than 15 billion miles (25 billion kilometers) away. Voyager 2 is over 13 billion miles (21 billion kilometers) from Earth. In fact, due to this distance, it takes over 23 hours to get a radio signal from Earth to Voyager 1, and 19½ hours to Voyager 2.

2024年11月6日 · Voyager 2 went on to explore Uranus and Neptune, and is still the only spacecraft to have visited those outer planets. The adventurers' current mission, the Voyager Interstellar Mission (VIM), will explore the outermost edge of the Sun's domain.

2022年8月17日 · Voyager 2 became the third spacecraft to visit Saturn when it arrived at its closest point to the ringed planet on Aug. 26, 1981, and took hundreds of pictures of the planet, its moons and its ...

2019年11月1日 · At a distance of about 11 billion miles (18 billion kilometers) from Earth — well beyond the orbit of Pluto — Voyager 2 had entered interstellar space, or the region between stars. Today, five new research papers in the journal Nature Astronomy describe what scientists observed during and since Voyager 2’s historic crossing.

2022年8月19日 · Voyager 2 conducted its observations of Jupiter between April 24 and Aug. 5, 1979, making its closest approach of 350,000 miles above the planet’s cloud tops on July 9. The spacecraft returned 17,000 images of Jupiter, many of its satellites, and confirmed Voyager 1’s discovery of a thin ring encircling the planet.
