  2. Jupiter - Wikipedia

    en.wikipedia.org/wiki/Jupiter

    Jupiter is the only planet whose barycentre with the Sun lies outside the volume of the Sun, though by 7% of the Sun's radius. [ 130 ] [ 131 ] The average distance between Jupiter and the Sun is 778 million km (5.20 AU) and it completes an orbit every 11.86 years.

  3. Rømer's determination of the speed of light - Wikipedia

    en.wikipedia.org/wiki/Rømer's_determination_of...

    Rømer and Cassini refer to it as the "first satellite of Jupiter". It orbits Jupiter once every 42½ hours, and the plane of its orbit is very close to the plane of Jupiter's orbit around the sun. This means that it passes some of each orbit in the shadow of Jupiter – an eclipse. Viewed from the Earth, an eclipse of Io is seen in one of two ...

  4. Grand tack hypothesis - Wikipedia

    en.wikipedia.org/wiki/Grand_Tack_Hypothesis

    Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.

    Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...

  6. Jupiter trojan - Wikipedia

    en.wikipedia.org/wiki/Jupiter_trojan

    The Jupiter trojans, commonly called trojan asteroids or simply trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each trojan librates around one of Jupiter's stable Lagrange points : either L 4 , existing 60° ahead of the planet in its orbit, or L 5 , 60° behind.

  7. Barycenter (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Barycenter_(astronomy)

    If Jupiter had Mercury's orbit (57,900,000 km, 0.387 AU), the Sun–Jupiter barycenter would be approximately 55,000 km from the center of the Sun (⁠ r 1 / R 1 ⁠ ≈ 0.08). But even if the Earth had Eris's orbit (1.02 × 10 10 km, 68 AU), the Sun–Earth barycenter would still be within the Sun (just over 30,000 km from the center).

    Jupiter was last in Gemini from June 2000 to July 2001 and June 2012 to June 2013. In astrology, Jupiter is the planet associated with good luck, and is thought to magnify the effects of the sign ...

  9. Heliocentric orbit - Wikipedia

    en.wikipedia.org/wiki/Heliocentric_orbit

    A heliocentric orbit (also called circumsolar orbit) is an orbit around the barycenter of the Solar System, which is usually located within or very near the surface of the Sun. All planets , comets , and asteroids in the Solar System, and the Sun itself are in such orbits, as are many artificial probes and pieces of debris .
