What is the Yarkovsky Effect? OSIRIS-REx presents the new 321Science video about how sunlight can affect the orbits of small asteroids. This video explores how the Yarkovsky effect occurs and how it can change the orbits of asteroids -- changing near misses to impacts or impacts to near misses. Two companion videos explain the terms thermal inertia and prograde/retrograde motion.
