  2. Comet Shoemaker–Levy 9 - Wikipedia

    en.wikipedia.org/wiki/Comet_Shoemaker–Levy_9

    The first impact occurred at 20:13 UTC on July 16, 1994, when fragment A of the [comet's] nucleus slammed into Jupiter's southern hemisphere at about 60 km/s (35 mi/s). Instruments on Galileo detected a fireball that reached a peak temperature of about 24,000 K (23,700 °C; 42,700 °F), compared to the typical Jovian cloud-top temperature of ...

  3. Galilean moons - Wikipedia

    en.wikipedia.org/wiki/Galilean_moons

    The numbers run from Jupiter outward, thus I, II, III and IV for Io, Europa, Ganymede, and Callisto respectively. [14] Galileo used this system in his notebooks but never actually published it. [13] The numbered names (Jupiter x) were used until the mid-20th century when other inner moons were discovered, and Marius' names became widely used. [14]

  4. Jupiter - Wikipedia

    en.wikipedia.org/wiki/Jupiter

    Jupiter's moons were classified into four groups of four, based on their similar orbital elements. [204] This picture has been complicated by the discovery of numerous small outer moons since 1999. Jupiter's moons are divided into several different groups, although there are two known moons which are not part of any group (Themisto and Valetudo ...

  6. Europa Clipper - Wikipedia

    en.wikipedia.org/wiki/Europa_Clipper

    [needs update] After entry into the Jupiter system, Europa Clipper will perform a flyby of Ganymede at an altitude of 500 km (310 mi), which will reduce the spacecraft velocity by ~400 m/s (890 mph). This will be followed by firing the main engine at a distance of 11 Rj (Jovian radii), to provide a further ~840 m/s (1,900 mph) of delta-V ...

  7. Stability of the Solar System - Wikipedia

    At one point, the two may fall into sync, at which time Jupiter's constant gravitational tugs could accumulate and pull Mercury off course, with 1–2% probability, 3–4 billion years into the future. This could eject it from the Solar System altogether [1] or send it on a collision course with Venus, the Sun, or Earth. [11]

  8. Galileo (spacecraft) - Wikipedia

    en.wikipedia.org/wiki/Galileo_(spacecraft)

    Galileo was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida.Named after the Italian astronomer Galileo Galilei, it consisted of an orbiter and an entry probe.

  9. Eccentric Jupiter - Wikipedia

    en.wikipedia.org/wiki/Eccentric_Jupiter

    An eccentric Jupiter is a Jovian planet that orbits its star in an eccentric orbit. [1] Eccentric Jupiters may disqualify a planetary system from having Earth-like planets (though not always from having habitable exomoons ) in it, because a massive gas giant with an eccentric orbit may eject all Earth mass exoplanets from the habitable zone ...
