It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn. One spacecraft, Voyager 2, also visited Uranus and Neptune.
Artist's depiction of Pioneer 10, the first spacecraft to visit Jupiter. The exploration of Jupiter has been conducted via close observations by automated spacecraft.It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.
This is a list of alleged extraterrestrial beings that have been reported in close encounters, claimed or speculated to be associated with unidentified flying objects (UFOs) (not to be confused with the meaning of the term "alien species" in the biological science of ecology). [1]
NASA's Juno spacecraft captured this view of Jupiter during the mission's 54th close flyby of the giant planet Sept. 7, 2023.
Voyager 2 ' s closest approach to Jupiter occurred at 22:29 UT on July 9, 1979. [3] It came within 570,000 km (350,000 mi) of the planet's cloud tops. [41] Jupiter's Great Red Spot was revealed as a complex storm moving in a counterclockwise direction. Other smaller storms and eddies were found throughout the banded clouds.
A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit. The planet is roughly the same diameter as Jupiter, but with six times the mass ...
In many cases it is not possible to have an exact value, and an estimated range is instead provided. The coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga. This list includes the four members of the multi-planet system that orbit HR 8799.
J1407b's disk has a 4-million km (2.5-million mi)-wide gap between radii 0.396 to 0.421 AU (59.2 to 63.0 million km; 36.8 to 39.1 million mi), which is believed to have been created by a nearly-Earth-sized (<0.8 M 🜨) exomoon orbiting within that gap and clearing out material, in a similar fashion to the shepherd moons of Saturn's rings.
