2018 in planets

Well, it was a pretty decent year for Jupiter, Saturn and Mars approaching in turn at our latitudes

This image has one frame per month for each planet. Each one grows and shrinks as they approach Earth in turn - Jupiter in early May, Saturn in June, and Mars in July. Shadows and phases shift from pointing to the right early in the year, to pointing to the left after each planet reaches opposition. The closer the planet, the more dramatic the variation in size.

Just as Mars gets big, a global dust storm blankets the planet in June, then features slowly emerge through July and August as the storm begins to subside. Remarkable bright polar storms have been a feature on Saturn since April. Unfortunately some bad luck has meant my July & August Saturns are a bit fuzzier! There's always lots of lovely storm action on Jupiter, including this year the demise of the South Tropical Disturbance near the Great Red Spot. Ganymede sneaks into March and June's shots.
