Pluto positions
Discovered in 1930, Pluto was considered the 9th planet in our solar system until 2006, but was downgraded to the new category of dwarf planet in 2006 . It has the extremely long orbital period of around 248 years, during which it is overtaken 247 times by the earth on the inner orbit and is in opposition to the sun. Because of the long period of rotation, it takes an average of more than 20 years for a zodiac sign. However, since its orbit is extremely steeply inclined towards the ecliptic with 17.16 ° , some signs of the zodiac, especially Scorpio, Pisces and Aries, are not passed through at all. During these years, there can only be limited talk of a conjunction with the sun, since in conjunction in spring, viewed from Earth, it is lowered from the ecliptic by almost the amount of its orbit inclination (April 10, 2087: 16.79 ° ), raised accordingly in autumn (October 16, 2227: 16.59 °).
In conjunction with Sagittarius in mid-January and Gemini in mid-July, the dwarf planet is close to its nodes with the ecliptic and occurs mostly once per 248-year cycle in January (January 11, 2019) and currently twice in July (July 14, 2019) 2078 and July 15, 2179) behind the sun.
Note in the table below, however, that the Pluto near the node between January 2018 and January 2020 decreases by about 33.35 angular minutes per year with an apparent solar diameter of about 32 minutes. Therefore this coverage can be missing in very rare cases. In contrast, between July 2177 and July 2179 it increases by about 22.4 minutes per year, which is why only one April coverage per cycle would be possible. On January 14, 2267, however, Pluto will hit the sun again very precisely with +1.12 ′ and again on July 17, 2426 (−14.84 ′) and July 19, 2427: (+7.46 ′) in July meet twice.
On September 4, 1989, Pluto was at 29.6556 AU solar distance in perihelion , where it will be again on September 14, 2237 at 29.6453 AU - in each case at the transition from Virgo to Libra or, since it is almost at its maximum there , at the transition from the bear guard to the snake. On February 20, 2114 it is at 49.3191 AU solar distance in the whale and south of the Aries in aphelion .
The following table shows the special constellations of Pluto for 2004–2024 and for all cycles of entry into new constellations between 1989 and 2238 together with the opposition loop; Coverings are marked in bold in the right column, the cycles around that of 2178 are also listed. Cycles with extreme distances in opposition and those with an extreme center angle to the sun in conjunction (along with neighboring cycles) are also listed with the respective extreme values bolded, as well as all cycles in which the value of the apparent size, rounded to two decimal places, changes. 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
- ↑ Calsky shows an occlusion for July 2178 only.
- ↑ a b CalSky is at coverages not sufficiently accurate (see also examples in Uranus positions ) Therefore, the central angle indicated by two Nachlomastellen are close a cover with Stellarium been determined (ecliptic coordinates to date).
- ↑ Plus positions on CalSky .com
- ↑ The apparent quantities of Pluto available at calsky.com only have two decimal places and differ considerably from calculated values !
- ↑ all dates in UT1
- ↑ a b relative to the ecliptic
- ↑ For central angles> 10 °, CalSky does not automatically determine the time of the conjunction. It has to be determined manually with the help of the central angle, which becomes minimal for the conjunction. If necessary, it is near the point in time of the distance from the earth.
