More specifically, to search for potentially hazardous asteroids (PHAs), that may pose a threat of impact.

NEOWISE data estimates that there are 4,700 1,500 potentially hazardous asteroids with a diameter greater than 100 meters.

It is classified as a near-Earth asteroid and a potentially hazardous asteroid.

Measure the Yarkovsky effect (a thermal force on the object) on a potentially hazardous asteroid and constrain the asteroid properties that contribute to this effect.
