Jupiter was the first of the Sun's planets to form, and its inward migration during the primordial phase of the Solar System affected much of the formation history of the other planets. Jupiter's atmosphere consists of 76% hydrogen and 24% helium by mass, with a denser interior.
Jupiter (Latin: Iūpiter or Iuppiter, [6] from Proto-Italic *djous "day, sky" + *patēr "father", thus "sky father" Greek: Δίας or Ζεύς), [7] also known as Jove (gen. Iovis), is the god of the sky and thunder, and king of the gods in ancient Roman religion and mythology.
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.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Jupiter’s striking Great Red Spot has puzzled astronomers for years. Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere.
A study by Southwest Research Institute, San Antonio, Texas, published June 6, 2011 (called the Grand tack hypothesis), proposes that Jupiter had migrated inward to 1.5 AU. After Saturn formed, migrated inward, and established the 2:3 mean motion resonance with Jupiter, the study assumes that both planets migrated back to their present positions.
In science class, we always learned that all the planets in our solar system orbit around the sun. Scientists have figured out this is not necessarily true.
NASA's Juno spacecraft recently flew by Jupiter, collecting crucial data -- and the best look we've gotten at the planet in a very long time. This is the closest photo of Jupiter anyone has seen ...
