To demonstrate Jupiter’s long orbital period (11.86 years), the planet passes the dim star 56 Sagittarii (56 Sgr on the chart). The star has been a reliable, but dim, signpost to watch the planetary motions of Jupiter and Saturn during the year.
When the Jovian Giant passes this way again, during a triple conjunction with the star, Jupiter first passes 56 Sgr on March 10, 2032. As Jupiter retrogrades, a second conjunction occurs, August 2. The third conjunction occurs November 1, 2032.
From this triple conjunction the next great conjunction is still 8 years away (October 31, 2040). By this date, Saturn has moved farther eastward compared to the starry background. Jupiter then overtakes the Ringed Wonder for the next Great Conjunction.
Meanwhile, the Great Conjunction of 2020 is 25 days away!
This evening Jupiter passes 1.8° to the lower left of 56 Sgr. Saturn is 3.3° to the upper left of the star and 4.9° to the lower right of Sigma Capricorni (σ Cap). With the bright moon in the eastern sky, use a binocular to view the starry background.
Farther eastward, the bright gibbous moon is to the lower left of rusty Mars. As with the starry background near Jupiter and Saturn, use a binocular to spot Mars 2.0° to the lower right of ε Psc, 3.0° to the lower left of δ Psc, and 2.2° to the upper right of 80 Piscium (80 Psc).
The stars ε Psc, 80 Psc, and Zeta Piscium (ζ Psc) form nearly an equilateral triangle. Watch Mars approach and move through the shape during the next several evenings.
The moon is at apogee at 6:29 p.m. CDT, 252,193 miles away.
