Yes, it applies to all small asteroids. However, Jupiter's gravitational effect
on the asteroid belt applies as well, and is the bigger factor of the two.
If you doing long term calculations of an
asteroid's orbit, you going to have to incorporate the Yarkovksy effect.
For short-term calculations, the Yarkovksy effect is so small it can be
ignored.
