　　The Great Red Spot

　　One distinctive feature of the planet Jupiter is the Great Red Spot, a massive oval of swirling reddish-brown clouds. Were Earth to be juxtaposed with the Great Red Spot, our planet would be dwarfed in comparison, with a diameter less than half that of the Great Red Spot. The Spot’s clouds, most likely tinted red as a result of the phosphorus that they contain, circulate in a counterclockwise direction. The outer winds require six Earth days to complete the circumference of the Great Red Spot, a length of time indicative of vastness of the Great Red Spot.
