ʻOumuamua (Hawaiian: first messenger arriving from afar; official name: 1I/2017 U1)[1] is an object from another star system that visited our solar system.

ʻOumuamua is the first interstellar object unambiguously identified that has visited our solar system.[2] Its appearance is very long and very narrow. Oumuamua was first discovered on 19 October 2017 using the Pan-STARRS1 telescope at the Haleakala Observatory in Hawaii.[3]
