2015 XX169 (also written 2015 XX169) is an Apollo asteroid that is a temporary horseshoe companion to the Earth, the tenth known Earth horseshoe librator. A close encounter with the Earth on 14 December 2015 caused the value of the semi-major axis of 2015 XX169 to drift slowly upwards, and the object evolved from an Aten asteroid to an Apollo asteroid about a year after this close approach. (en) 2015 XX169 est un astéroïde Apollon, compagnon de la Terre temporairement sur une orbite en fer à cheval, le dixième librateur connu sur une orbite en fer à cheval par rapport à la Terre. Son passage près de la Terre le 14 décembre 2015 a fait que la valeur du demi-grand axe de 2015 XX169 a légèrement augmenté, faisant passer cet astéroïde de la catégorie des astéroïdes Aton à celle des astéroïdes Apollon environ un an après ce passage rapproché.
