Los Asteroides Potencialmente Peligrosos (PHAs) son rocas espaciales mayores de aproximadamente 100m que pueden acercarse a la Tierra más de 0.05 AU. Ninguno de los PHAs conocidos está en trayectoria de colisión con nuestro planeta, aunque los astrónomos están encontrando nuevos todo el tiempo.
El 6 de diciembre de 2020 había 2037 asteroides potencialmente peligrosos.
