The International Space Station passes Jupiter and Saturn this evening as seen across the Midwest. A clearing sky permitted viewing this evening. At its brightest, the ISS was easily brighter than Jupiter.
As for the planets, Jupiter is 8.0° to the right of Saturn. Jupiter passes Saturn in a Great Conjunction on December 21, 2020. This is the closest conjunction since the Jupiter – Saturn conjunction of 1623. Great Conjunctions occur every 19.6 years, but this is the closest for nearly 400 years.
Before Jupiter passes Saturn in our sky, Jupiter edges past Saturn as viewed on the solar system’s scale in what is known as a heliocentric conjunction. This occurs on November 2.
Continue to look for Jupiter and Saturn each evening. During the next several weeks, watch Jupiter close the gap to Saturn.
Here is a daily summary about the planets during September.

It passes the bright stars that are prominent in the evening sky during the winter season in the northern hemisphere. The stars have been making their first appearances in the morning sky during summer. At this hour, Procyon and bright Sirius are the last stellar duo to appear.
August 6, 2021: In the northern hemisphere, summer’s midpoint occurs today at 6:27 p.m. CDT.
July 31, 2021: The slightly gibbous moon, nearing its Last Quarter phase, is in the southeast as morning twilight begins. It is near the planet Uranus, easily within reach of a binocular. Mira, a variable star, reaches its brightest next month.
July 29, 2021: In a challenging-to-see conjunction, Mars passes 0.6° to the upper right of the star Regulus.
July 27, 2021: Evening Star Venus, Mars, Saturn and Jupiter are in the evening sky. Mars is nearing its conjunction with Regulus in two evenings.
