The chart shows the path of Jupiter across the background stars over the course of the year. Stars to magnitude +7.5 are shown. The white circles represent the planet on the first day of the month and are scaled according to apparent magnitude. The faint paths before the first circle and after the last circle represent the planet's positions in December of last year and January of next. In general, the planet moves from right to left except when it's in retrograde and proceding in the opposite direction.
The lower chart shows how the appearance of Jupiter changes over the year. Below each image is listed the date, the apparent magnitude, the apparent diameter of the disk (in arc-seconds) and the geocentric distance (in au). Note that Jupiter appears distinctly larger and brighter near the time of opposition.
Jupiter begins the year in the evening sky, slowly moving through the faint background stars of Pisces and Cetus. It has a close pairing with Venus in early March by which time it is getting low to the horizon. Conjunction takes place in April, after which Jupiter moves into the morning sky. By July it is rising around midnight and opposition occurs in November. The Moon occults the gas giant four times between February and May.

The dates, times and circumstances of all planetary and lunar phenomena were calculated from the JPL DE406 solar system ephemeris using the same rigorous methods that are employed in the compilation of publications such as The Astronomical Almanac.
