Jupiter positions

from Wikipedia, the free encyclopedia

The Jupiter takes almost 12 years for a solar circumnavigation, which is why he averaged just over one per year zodiac signs travels. After 12 years, the earth has finally overtaken it 11 times on the inner orbit (has been in opposition to the sun 11 times ) and has been in conjunction with the sun just as often , thus starting a new cycle. If it is in opposition in mid-July, as in 2020, the time is nominally in the zodiac sign of Cancer, but the sun is one constellation behind, in Gemini, since the earth's axis has changed by around 30 ° since the constellations were determined in the calendar about 2100 years ago (≈360 ° × 2,100 ÷ 25,800, see precession constant ), which corresponds to the average east-west circumference of a zodiac sign. The opposite Jupiter is therefore six constellations further / back, in Sagittarius.

In 12 years, the calendar dates of Jupiter will jump about 5 days later, ie the next opposition is a sixth constellation further. After 84 years it has therefore jumped by about 35 days and the original calendar date is one opposition ago. Therefore, after 83 years, the calendar dates are almost exactly the same as the original ones or are only around a day earlier. During this period (7 × 11 -1 =) 76 individual cycles took place.

visibility

In the constellations of Pisces and Whale, which then face the Sun, which is roughly in Virgo in September and October, Jupiter is particularly close to the Sun with less than 5 AU . If there is opposition during these months, it is therefore less than 4 AU away from the earth ( apparent size up to 50 arc seconds ) and then has an apparent magnitude of around −2.9 mag. In perihelion , Jupiter stood and still stands on May 20, 1999 (4.9505 AU), on March 17, 2011 (4.9484 AU), on January 20, 2023 (4.9510 AU), on December 5, 2034 (4 , 9527 AU), on November 1, 2046 (4.9534 AU), on Sep. 2058 (4.9514 AU), on July 11, 2070 ( 4.9483 AU), on May 15, 2082 (4.9505 AU) and on March 29, 2094 (4.9525 AU), whereby 2011 and 2070 also include the 4.95 AU were and will be undercut. The 21st century opposition closest to Jupiter with a distance of 3.9526426 AU will take place on September 26, 2022 and −2.94 may be bright. <Calsky />

In the constellation Virgo or with opposition in March and April, however, it is 4.4 AU and further away (apparent size only around 44 "), so that its apparent brightness drops to about −2.5 mag. In aphelion , Jupiter stood and still stands on April 14, 2005 (5.4565 AU), on February 17, 2017 (5.4565 AU), on December 28, 2028 (5.4539 AU), on November 18, 2040 (5 , 4529 AU), October 7, 2052 (5.4533 AU), August 8, 2064 (5.4564 AU), June 13, 2076 ( 5.4567 AU), April 21, 2088 (5.4541 AU) AE) and on March 11th 2100 (5.4526 AU), with 5.456 AU being exceeded in 2005, 2017, 2064 and 2064. The opposition furthest from Jupiter in the 21st century with 4.4567810 AU was already on February 2, 2005 and −2.47 mag bright. <Calsky />

Orbit inclination

The orbit of Jupiter is inclined by 1,304 ° to the ecliptic , whereby it is maximally lowered in conjunction with the end of March. It is then about 4.95 AU from the sun and 5.95 AU from the earth, which is why it is lowered by around 1.304 × 4.95 ÷ 5.95 ≈ 1.085 ° (1.08 ° = 64.8 'lowering reached in the 21st century on April 6, 2011, March 26, 2070, March 31, 2082, and April 5, 2094). In the conjunction around the end of September, when it is about 5.45 AU from the Sun and 6.45 AU from the Earth, it is raised by about 1.304 ° × 5.45 ÷ 6.45 ≈ 1.102 ° (1.10 ° = 66.0 'increases in the 21st century will only be achieved on September 30, 2028 and October 4, 2040). If there is a conjunction around the turn of the year and around the middle of the year, on the other hand, the central angle is less than 15 angular minutes , so that there is a cover . This is usually the case once per twelve-year cycle, but in rare cases it can fail in one of the two or both seasons. because Jupiter jumps around the nodes of its orbit with the ecliptic from conjunction to conjunction by up to 37 minutes, i.e. more than the solar diameter of 32 minutes plus its own by less than a minute. On December 17, 2078 (+16.9 ') and on January 19, 2080 (–20.2'), eclipses will just be missed, as well as on June 13, 2084 (−20.0 ') and on July 19 2085 (+17.8 '). Therefore, between July 14, 2073 (+12.7 ') and December 22, 2090 (-11.8') there will be no coverage for almost 17½ years.

Table of constellations from 2004 to 2047

The following table shows the special constellations of Jupiter together with planetary loops for the years 2004–2047 and the transition cycles in the vicinity of the perihelion up to 2094. Coverings are marked in bold in the right column, furthermore extreme values ​​of the number columns are bold. If the opposition lies on the border between two constellations, it should be noted that because of the retrograde Jupiter moves into the first-named constellation, while it has actually already been in the second-named constellation, which it only passes through again afterwards.

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). Starting in 2010, the cycles are grouped into twelve-year bundles, of which just under seven then become an 83-year bundle until 2093. The first annual cycle of this block contains both the brightest opposition and the highest reduction in conjunction within 12 years. After three twelve-year cycles, the highest drop has already migrated to the previous one-year cycle; after six twelve-year cycles, the opposition in the immediately preceding one-year cycle has also become slightly brighter, until in cycle 2092/2094 there is again almost exact correspondence with the 2010/2011 cycle.
