5 Must Know Facts For Your Next Test

1. The Great Red Spot is a massive, oval-shaped storm that is larger than the entire Earth, with a diameter of approximately 10,000 to 15,000 kilometers.
2. The storm has been observed continuously since the late 17th century, making it one of the longest-lived and most studied features in the solar system.
3. The Great Red Spot is characterized by its distinct reddish-orange color, which is believed to be caused by the presence of complex organic compounds in the upper atmosphere.
4. The storm is an anticyclonic feature, meaning it rotates in the opposite direction of the surrounding lower-pressure systems, creating a powerful vortex that can reach wind speeds of up to 600 kilometers per hour.
5. The Great Red Spot plays a crucial role in understanding the complex atmospheric dynamics of Jupiter, as its behavior and interactions with other features provide insights into the planet's overall weather patterns and climate.
