Giant Jupiter appears in the predawn eastern sky following its conjunction behind the Sun on 2017 OCT 26. Western quadrature (90° from Sun) will be reached on 2018 FEB 10. Apparent retrograde motion in right ascension will begin on MAR 09.
Opposition from the Sun will occur on 2018 MAY 08 with Jupiter in the sky all night. At that time it will be in the constellation Libra at a declination of 16.1° south of the celestial equator. Its south pole will be tilted by 3.4° toward Earth. The orbital planes of its four great Galilean satellites are similarly tilted. Greatest brilliance for this apparition is expected around MAY 09 at stellar magnitude -
Apparent direct motion in right ascension will resume on 2018 JUL 10. Eastern quadrature will be reached on AUG 06 before conjunction behind the Sun on NOV 26.
Jupiter will appear near other bright planets on the following dates: Mars 2018 JAN 06 & Mercury OCT 29. It will not conjunct any first magnitude stars.
The Moon will appear near Jupiter on 2017 DEC 14, 2018 JAN 11, FEB 07, MAR 07, APR 03, APR 30, MAY 27, JUN 23, JUL 20, AUG 17, SEP 13 OCT 11 & NOV 08. There will be no lunar occultations of Jupiter during this apparition.
