Saturn's Tilt Changes

Saturn's Tilt Changes
This is a mosaic image that shows the orientation changes in Saturn's 26.7° axial tilt when viewed from Earth over a period of 30 years. This is an ongoing Frosty Drew Observatory project which started in 2012. Saturn will take 29.5 years to complete one full orbit around the Sun. Saturn is also tilted 27.6° on its axis, and the rings are situated over Saturn’s equator. As Saturn continues its orbit around the Sun, its tilt remains the same, though the orientation of the tilt will appear to change if viewing Saturn from the vantage point of the Sun. In April 2003, Saturn reached its Winter Solstice, which would have placed the rings at 26.7° tilted away from the Sun. In May 2017 Saturn reached its Summer Solstice, placing the rings at 26.7° tilted towards the Sun. In May 2025, Saturn will reach its Autumnal Equinox, which will place Saturn’s rings neither tilted towards or away from the Sun.
