Information about Oumuamua

Wiki source

ʻOumuamua is a small object, estimated to be about 100 m–1,000 m × 35 m–167 m × 35 m–167 m (328 ft–3,281 ft × 115 ft–548 ft × 115 ft–548 ft) in size. It has a dark red color, similar to objects in the outer Solar System. ʻOumuamua showed no signs of a comet tail despite its close approach to the Sun, but has since undergone non-gravitational acceleration, potentially consistent with a push from solar radiation pressure. It has significant elongation and rotation rate, so it is thought to be metal-rich with a relatively high density. ʻOumuamua is tumbling, rather than smoothly rotating, and is moving so fast relative to the Sun that there is no chance it originated in the Solar System. It also means that ʻOumuamua cannot be captured into a solar orbit, so it will eventually leave the Solar System and resume traveling through interstellar space. ʻOumuamua's system of origin and the amount of time it has spent traveling amongst the stars are unknown.
