The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere. Astronomical bodies include stars, planets, dwarf planets and small Solar System bodies such as comets and minor planets (e.g., asteroids), as well as natural satellites and minor-planet moons.
For example, during the opposition of 17 December 2002, Saturn appeared at its brightest due to the favorable orientation of its rings relative to the Earth, [178] even though Saturn was closer to the Earth and Sun in late 2003. [178] From time to time, Saturn is occulted by the Moon (that is, the Moon covers up Saturn in the sky). As with all ...
The South Pole is at an altitude of 9,200 feet (2,800 m) but feels like 11,000 feet (3,400 m). [34] Centripetal force from the spin of the planet throws the atmosphere toward the equator. The South Pole is colder than the North Pole primarily because of the elevation difference and for being in the middle of a continent. [35]
Pole stars of other planets are defined analogously: they are stars (brighter than 6th magnitude, i.e., visible to the naked eye under ideal conditions) that most closely coincide with the projection of the planet's axis of rotation onto the celestial sphere. Different planets have different pole stars because their axes are oriented differently.
Afternoon analemma photo taken in 1998–99 in Murray Hill, New Jersey, U.S., by Jack Fishburn.The Bell Laboratories building is in the foreground. In astronomy, an analemma (/ ˌ æ n ə ˈ l ɛ m ə /; from Ancient Greek ἀνάλημμα (analēmma) 'support') [a] is a diagram showing the position of the Sun in the sky as seen from a fixed location on Earth at the same mean solar time over ...
The south celestial pole over the Very Large Telescope [3] Locating the south celestial pole. The south celestial pole is visible only from the Southern Hemisphere. It lies in the dim constellation Octans, the Octant. Sigma Octantis is identified as the south pole star, more than one degree away from the pole, but with a magnitude of 5.5 it is ...
[citation needed] [dubious – discuss] In large cities, about 300 to 500 stars can be seen depending on the extent of light and air pollution. [citation needed] The farther north, the fewer are visible to the observer. [citation needed] The brightest star in the night sky is located in the southern celestial hemisphere and is larger than the Sun.
In the near future between 2025 and 2038 Saturn's southern hemisphere will be visible, giving observers the possibility to observe a southern GWS. If such southern GWS exists and behaves similar to most northern GWS, the next GWS could occur after May 12, 2032 when the south pole of Saturn is most inclined towards to the sun. [5]
