Astronomy Picture Of The Day: Maximun Wind Speed on Planets!!!

 

Black Hole@konstructivizm
The wind speeds across our Solar System range from absolute silence to supersonic violence. While a severe hurricane on Earth is terrifying, it would be considered a gentle breeze on the outer gas giants. Neptune — 2,100 km/h: The undisputed champion of wind. Its winds move faster than the speed of sound on Earth, driven by mysterious internal heat despite being so far from the Sun. Saturn — 1,800 km/h: These jet streams are concentrated mostly at the equator, creating massive, long-lasting storms that dwarf our entire planet. Uranus — 900 km/h: Despite its "ice giant" sibling Neptune being faster, Uranus still hosts winds twice as powerful as Earth's strongest cyclones. Jupiter — 600+ km/h: The Great Red Spot is a centuries-old storm where winds reach speeds that would level any structure on Earth. Venus — 400 km/h: While the surface air is sluggish and thick, the upper clouds "super-rotate," circling the entire planet in just four Earth days. Earth — 400 km/h: Our record wind speeds occur only in the most extreme hurricanes or tornadoes, barely reaching the average speeds of the outer planets. Mars — 100 km/h: Martian air is very thin, so even though these winds can trigger global dust storms, they wouldn't feel very strong against your skin. Mercury — 0 km/h: With no atmosphere to speak of, there is no air to move. It is a world of eternal, eerie stillness. From the vacuum of Mercury to the supersonic screams of Neptune, planetary weather highlights the extreme forces at play in our cosmic neighborhood.
