Interstellar object Oumuamua has certainly attracted the attention of the astronomy community and general public at large. How could it not with recent headlines such as "Interstellar object may have been alien probe" and statements like "'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," in papers released by respected institutions.
Oumauamua, discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii presented an aura of mystery from the start. At first the object was determined to be a comet, and then it was describe as an asteroid, and finally declared as a new class of interstellar object. Its name a Hawaiian word meaning "visitor from afar arriving first" seems appropriate consider the objects classification. While its estimated speed of 196,000 mph and accelerating seems to be agreed on, the size has varied widely. Initial estimates of a length of 440 meters have been revised in more recent figures of 100 meters or less.
Theories of origin and makeup of Oumauamua may be debated and evolve for years to come. As it speeds toward exiting our solar system and back to interstellar space, so goes our opportunity to gather more data with it. Oumuamua will certainly leave behind a legacy mystery and unanswered questions.
