NASA | 3,000 Comets for SOHO

The video discusses the SOHO mission, initially aimed at studying the Sun, which unexpectedly became a prolific comet discoverer. SOHO's unique instruments allow it to observe comets that are not visible from Earth. The video explains different comet families, their trajectories influenced by the Sun's gravity, and highlights the speed of sun-grazing comets. It also notes that many comets discovered by SOHO have survived the Sun's intense radiation, and emphasizes SOHO's significant contribution to comet discovery, despite it not being its original mission.

What was the original mission of the SOHO spacecraft?

• To monitor Earth's atmosphere

• To explore the outer solar system
