Giant Jupiter appears in the predawn southern sky following its conjunction behind the Sun on 2016 SEP 26. Western quadrature (90° from Sun) was reached on 2017 JAN 11 shortly before late evening risings commenced. Apparent retrograde motion in right ascension will start on FEB 06.
Opposition from the Sun will occur on 2017 APR 07 when Jupiter will be in the sky all night. At that time it will in the constellation Virgo at a declination of 5.7° south of the celestial equator. Its south pole will be tilted by 3.8° toward Earth. The orbital planes of its four great Galilean satellites will be similarly tilted. Greatest brilliance for this apparition is expected around that same date at stellar magnitude -
Apparent direct motion in right ascension will resume on 2017 JUN 09. Eastern quadrature will be reached on JUL 05 before conjunction behind the Sun on OCT 26.
Jupiter will appear near other bright planets and stars on the following dates: Spica 2017 FEB 01, Spica SEP 11.
The Moon will appear near Jupiter on 2017 JAN 19, FEB 15, MAR 14, APR 10, MAY 07, JUN 03, JUL 01, JUL 28, AUG 25, SEP 22. There will be no lunar occultations of Jupiter during this apparition.
