Neptune positions
The Neptune takes about 165 years for a Sonnenumkreisung and therefore an average of almost 14 years for a sign of the zodiac . In the 165 years of a cycle, it is overtaken 164 times by earth on the inner track and comes into opposition . In conjunction , the central angle to the sun is almost zero (on February 2, 2004 and August 3, 2084 it is less than 2) to a good 102 angular minutes below (August 3, 2084) and above (November 6, 2126) the sun, with occultations (Angle is <16 ') always take place eight in a row (January / February 2000–2007, July / August 2081–2088).
In perihelion Neptune is on 13 September 2042 and then only 29.8066 AE from the Sun; shortly before that, on October 29, 2041, it is closest to the earth with opposition at 28.81438 AU. In the aphelion of Neptune stands at the December 1, 2125 and then 30.3391 AE from the Sun; shortly before that, on April 30, 2125, it is at its greatest distance from the earth with opposition at 29.33242 AU. These rather small differences mean that when Neptune is in opposition, it always has an apparent size of 2.34 to 2.37 arc seconds and its apparent magnitude remains roughly constant at 7.7 mag.
The following table lists the special constellations of Neptune together with planetary loops for the years 1997–2021 as well as all entry cycles into a new constellation and all cycles with extreme values for a complete super cycle up to 2162; Coverings are marked in bold in the right column, as are extreme values in all number columns. The values relate to 51.5 ° north latitude ( Dortmund , Göttingen , Halle (Saale) ) and the date, if applicable, to Dortmund (or Bern ; 7.5 ° east longitude).

Remarks
- ↑ a b CalSky is not sufficiently precise in the case of occultations (see also examples in uranium positions ). Therefore, the central angles indicated with two Nachloma digits have been determined for occlusion with Stellarium (ecliptical coordinates to the date).
