AS101 Lecture Notes - Lecture 5: Polar Regions Of Earth, Full Moon
Document Summary
Jupiter and saturn are readily observable with the unaided eye and have been observed for hundreds of years; uranus was the first planet to have been. "discovered" (by w. and c. herschel in 1781) and neptune was found (1846) because of the perturbations in uranus" orbit and subsequent calculations using. Obliquity, the inclination of a planet"s equator to its orbital plane, is minimal for. Jupiter (3 - resulting in no seasons), similar to earth"s for saturn and neptune (resulting in well-defined seasons). It seems peculiar to talk about atmospheres for the gas giants when they are mostly just that gas but their gaseous layers are remarkably similar to terrestrial atmospheres just more of them. We have learned about jovian atmospheres (down to their liquid cores) from some. Earth-bound observations but more recently from nasa"s galileo spacecraft, which dropped a probe into jupiter"s atmosphere to a depth of 300 km before burning up.
