Great Red Spot On Jupiter Keeps Shrinking, Record-Breaking Small Size This Year?

Earlier this year, planetary scientist Amy Simon reported that the Great Red Spot spanned 14,750 kilometers (9,165 miles) in longitude and 10,500 kilometers (6,525 miles) in latitude. However, Damian Peach’s recent measurements challenge these figures, indicating a significant reduction in size.

Peach utilized the WinJUPOS program to analyze his high-resolution images, determining the Great Red Spot’s diameter at 12,500 kilometers (about 7,770 miles) on November 6, 2023. If verified, this measurement would mark the GRS as the smallest ever recorded, surpassing its previous record of 41,000 kilometers (25,500 miles) in the late 1800s.
