The effect of this tiny thrust on the object’s orbit depends on how it spins. If the spin goes one way, Yarkovsky thrust adds to the orbital speed and the asteroid moves outward, away from the sun.

The Yarkovsky effect sharpens the picture of how potentially hazardous 1999 RQ36 could be in the future. The 1,640-foot diameter asteroid is expected to pass by Earth in 2135 at around 220,000 miles.

The Yarkovsky effect is named for the nineteenth-century Russian engineer who first proposed the idea that a small rocky space object would, over long periods of time, ...

As for the 2068 encounter, that cannot be ruled out, at least not yet, owing to how the Yarkovsky effect is influencing Apophis. Asteroids, because they’re exposed to the Sun’s rays, absorb a ...

Asteroid 1999 RQ36 is about one-third of a mile wide (0.5 km). Its path around the sun has been altered by about 100 miles (160 km) over the past 12 years due to the Yarkovsky effect, the study finds.

The Yarkovsky effect is named for the 19th-century Russian engineer who first proposed the idea that a small rocky space object would, over long periods of time, ...

The Yarkovsky effect works by changing the amount of light an asteroid gives off. As an asteroid rotates, the surface that has been heated by the sun moves away to face space and radiates infrared ...

The Yarkovsky effect is named for the 19th-century Russian engineer who first proposed the idea that a small rocky space object would, over long periods of time, ...

The Yarkovsky effect, or Yarkovsky acceleration, is caused by the sun heating the space rock unevenly, resulting in a "process that slightly changes the orbit of the asteroid," the statement added.

Now, a new study shows the asteroid is drifting away from its previously predicted orbit by about 557 feet (170 meters) a year due to the Yarkovsky effect, lead author and University of Hawaii at ...
