  We present an updated set of near-Earth asteroids with a Yarkovsky-related
semimajor axis drift detected from the orbital fit to the astrometry. We find
87 reliable detections after filtering for the signal-to-noise ratio of the
Yarkovsky drift estimate and making sure the estimate is compatible with the
physical properties of the analyzed object. Furthermore, we find a list of 24
marginally significant detections, for which future astrometry could result in
a Yarkovsky detection. A further outcome of the filtering procedure is a list
of detections that we consider spurious because unrealistic or not explicable
with the Yarkovsky effect. Among the smallest asteroids of our sample, we
determined four detections of solar radiation pressure, in addition to the
Yarkovsky effect. As the data volume increases in the near future, our goal is
to develop methods to generate very long lists of asteroids with reliably
detected Yarkovsky effect, with limited amounts of case by case specific
adjustments. Furthermore, we discuss the improvements this work could bring to
impact monitoring. In particular, we exhibit two asteroids for which the
adoption of a non-gravitational model is needed to make reliable impact
predictions.
