Saturn would later have begun to migrate inwards at a faster rate than Jupiter until the two planets became captured in a 3:2 mean motion resonance at approximately 1.5 AU (220 million km; 140 million mi) from the Sun. [33] This changed the direction of migration, causing them to migrate away from the Sun and out of the inner system to their ...
The composition of Jupiter's atmosphere is similar to that of the planet as a whole. [2] Jupiter's atmosphere is the most comprehensively understood of those of all the giant planets because it was observed directly by the Galileo atmospheric probe when it entered the Jovian atmosphere on December 7, 1995. [29]
The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
This caused Jupiter to move slightly inward. [c] Those objects scattered by Jupiter into highly elliptical orbits formed the Oort cloud; [47] those objects scattered to a lesser degree by the migrating Neptune formed the current Kuiper belt and scattered disc. [47] This scenario explains the Kuiper belt's and scattered disc's present low mass.
These include the equivalence of mass and energy (E = mc 2), length contraction (moving objects shorten), [Note 9] and time dilation (moving clocks run more slowly). The factor γ by which lengths contract and times dilate is known as the Lorentz factor and is given by γ = (1 − v 2 / c 2 ) −1/2 , where v is the speed of the object.
Neptune's mass of 1.0243 × 10 26 kg [8] is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter. [g] Its gravity at 1 bar is 11.15 m/s 2, 1.14 times the surface gravity of Earth, [71] and surpassed only by Jupiter. [72] Neptune's equatorial radius of 24,764 km [11] is nearly four ...
The stability of the Solar System is a subject of much inquiry in astronomy. Though the planets have historically been stable as observed, and will be in the "short" term, their weak gravitational effects on one another can add up in ways that are not predictable by any simple means. For this reason (among others), the Solar System is chaotic ...
The lines that crews plan to move underground stretch more than 45 miles and serve about 900 customers, according to a spokesperson. The U.S. Census Bureau estimates that there are more than 4,300 ...
