Yarkovsky effect
The "Gaia" mission of the European Space Agency, launched in December 2013, has been tasked with measuring the Yarkovsky effect on near-Earth asteroids (NEAs). The Yarkovsky effect is a small non-gravitational force on rotating bodies that can affect their trajectories. Its effect on small bodies like asteroids can be significant and needs to be taken into account in predicting an asteroid's position. has been selected as one of the most promising NEAs for this measurement by "Gaia".
