📡🎥 سیارهٔ زحل [🔗]، به عنوان دومین سیارهٔ بزرگ در منظومهٔ خورشیدی و ۹ برابر زمین، در فاصلهٔ ۱.۴ میلیارد کیلومتری از ما قرار دارد. یک‌بار چرخش این سیاره به دور خورشید، ۲۹ سالِ زمینی طول می‌کشد و یک فصل در این سیاره بیش از ۷ سالِ زمینی است.

شکل‌گیری فصل‌های جدید، به‌خاطر انحراف محوریِ سیاره در مدارِ حرکت به دور خورشید است؛ انحراف کرهٔ زمین در حرکتِ مداری‌اش به دور خورشید معادل با ۲۳.۴ درجه است [🔗]. سیارهٔ زحل نیز چنین انحرافی دارد (۲۷ درجه) که باعث شکل‌گیری فصل‌های جدید، تغییرات آب و هوایی، طوفان‌ها و ... می‌شود.

طبق اندازه‌گیری‌های تلسکوپ فضایی #هابل، بین سال‌های ۱۳۹۷ تا ۱۳۹۹، روشنایی استوای زحل بین ۵ تا ۱۰ ٪ افزایش پیدا کرده، سرعت بادها/طوفان‌ها در استوا به ۱۶۰۰ کیلومتر بر ساعت رسیده؛ بین سال‌های ۱۳۸۳ تا ۱۳۸۸ حدود ۱۳۰۰ ک.ب.س. بود. [۲۸ اسفند ۱۳۹۹] — 🌐 — [پست قبل: 🔗]
