Yarkovsky Effect on Asteroids

TNRTB Archive - Retained for reference information

The number, placement, and distribution of asteroids in the solar system plays a crucial role in determining the frequency and intensity of mass extinction events on Earth which in turn are critical for obtaining the just right history of life on Earth so that humans can exist there briefly. For a long time astronomers believed that the Yarkovsky effect (movement caused by uneven emission of absorbed solar radiation) moved or removed a large number of main-belt asteroids over the solar system’s history. Now, for the first time, astronomers have directly detected Yarkovsky effect movement in a nearby asteroid. This discovery confirms that the reflectivities and shapes of main-belt asteroids must be fine-tuned for human life to be possible.
