Overview
Archive NoteThe Great Red Spot is a long-lived high-pressure anticyclonic storm, distinct from typical low-pressure terrestrial hurricanes. NASA and the Hubble Space Telescope have followed its changing clouds and circulation.
Its horizontal span has varied substantially: a NASA historical description used about 15,400 miles, whereas Hubble reported about 10,250 miles across in 2014. Those figures belong to different observation epochs, not today's diameter.
