  3. SparkNotes - Wikipedia

    en.wikipedia.org/wiki/SparkNotes

    TheSpark.com was a literary website launched by four Harvard students on January 7, 1999. Most of TheSpark's users were high school and college students. To increase the site's popularity, the creators published the first six literature study guides (called "SparkNotes") on April 7, 1999. [1] [3] [4] In 2000, the creators sold the site to iTurf ...

    [5] [1] From infrared thermal measurements by the WISE spacecraft, Kalyke's albedo is measured at 2.9%, corresponding to a diameter of 6.9 kilometres. [ 3 ] It orbits Jupiter at an average distance of 23,181,000 km in 766.61 days, at an inclination of 166° to the ecliptic (165° to Jupiter's equator), in a retrograde direction and with an ...

  5. 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.

    It received the temporary designation S/2003 J 7. [ 5 ] [ 6 ] Aoede is about 10 kilometres in diameter, and orbits Jupiter at an average distance of 23,044,000 km in 714.657 days, at an inclination of 160° to the ecliptic (162° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.4311.

  7. Kepler orbit - Wikipedia

    en.wikipedia.org/wiki/Kepler_orbit

    An elliptic Kepler orbit with an eccentricity of 0.7, a parabolic Kepler orbit and a hyperbolic Kepler orbit with an eccentricity of 1.3. The distance to the focal point is a function of the polar angle relative to the horizontal line as given by the equation ( 13 )

    [14]: 1, 5 [7]: 1 The innermost ring of J1407b's disk extends out to a radius of 0.206 AU (30.8 million km; 19.1 million mi) and is the most opaque region of the disk. [ 14 ] : 9 Assuming the rings have a mass density proportional to their opacity, the total mass of J1407b's disk is roughly 100 lunar masses (1.23 Earth masses ).
