Oumuamua is a peculiar space rock purported to be many things, with some observers suggesting extraterrestrial relations with the first known interstellar visitor.
However, scientists have linked its physical traits to those belonging to conventional asteroids. An example of such similarity is noticed in its capacity for gaseous jet propulsion.
First sighted in 2017, ongoing research continues as the unique object leaves stellar regions of the solar system for deeper space through a sudden speedup phenomenon.
Theories abound to its origin and identity, with claims of Oumuamua being a nascent planet booted out of orbit, a dehydrated comet or an itinerant shard of ice.
