The Cassini-Huygens mission studied which planet famous for a hexagonal storm at its north pole and moons Enceladus and Titan?

• A. Jupiter
• B. Mars
• C. Saturn
• D. Venus

Answer: (C)

This item is asking you to connect a mission to the planet it studied, based on distinctive features. The Cassini-Huygens mission was focused on Saturn and its system. Saturn is famous for a hexagonal storm at its north pole, a long-lasting atmospheric feature that Cassini helped map in detail. The mission also studied Saturn’s moons Enceladus and Titan, with Enceladus showing icy plumes and Titan boasting a thick atmosphere and methane lakes. The Huygens probe even landed on Titan, giving direct surface measurements.

Jupiter has a well-known Great Red Spot, not a hexagonal storm, and Enceladus and Titan belong to Saturn’s system. Mars and Venus don’t have this hexagonal storm feature and aren’t associated with Enceladus or Titan. So Saturn is the planet described.
