Difference between equinox-2010 for Saturn from previous three
Вісник Астрономічної школи, 2020 Saturn's equatorial plane has an inclination of 26.75° to the plane of its orbit. Therefore, its atmosphere is characterized by seasonal changes. Because of the eccentricity of 0.056 orbit, the southern hemisphere receives 25% more energy from the sun ...

Searching for Saturn's X-rays during a rare Jupiter Magnetotail Crossing using Chandra [PDF]
, 2021 Every 19 years, Saturn passes through Jupiter's 'flapping' magnetotail. Here, we report Chandra X-ray observations of Saturn planned to coincide with this rare planetary alignment and to analyse Saturn's magnetospheric response when transitioning to this unique parameter space.
