Oumuamua asteroid is interstellar object scientists mention name as 1l/2017 U1 and it was first detected by the pan-Starrs telescope which located at haleaklā observatory, hawai and discoverered by Robert Weryk .

Oumuamua is in cigar-shaped and move forward in tumbling motion. That's why scientists detected something object is moving. 

First scientists decided it is comet and mention name as  C/2017 U1 after some time they found something strange where the comet has gaseous tail but Oumuamua does not contain gaseous tail then they designated that it is asteroid and mention name as A/2017 U1 but scientists give designation and create universal for all interstellar object as l and give name as 1l/2017 U1.

Now Oumuamua travelling between  the Saturn orbit and Neptune.

Scientists didn't know Oumuamua asteroid is made up of  rock or metal.

Oumuamua travel about 80km/sec that's why it was easily escape from sun gravity. 

about 85,700 miles per hour

Two of NASA's area telescopes (Hubble and Spitzer) half-track the article traveling regarding eighty five,700 miles per hour (38.3 kilometers per second) relative to the Sun. Its outward-bound path is regarding twenty degrees higher than the plane of planets that orbit the Sun.

Oumuamua closest approach to Earth when it come at 0.16 AU of Earth and 60 times distance of moon and closest point to sun is 0.25 AU of our star on September 9, 2017.

a messenger from afar inbound 1st

In the Hawaiian language, 'Oumuamua suggests that “a messenger from afar inbound first”, a respect to its scout-like nature.

Most scientists, however, suppose 'Oumuamua's wonky acceleration was seemingly thanks to a phenomenon. In June, an enquiry team projected that solid H was blasting invisibly off the celestial body object's surface and inflicting it to hurry up.

How fast asteroids travel?

 it is traveling about 138,000 kilometers per hour relative to the Sun.

Assuming that alternative planetary systems match the system, Pan-STARRS shouldn't have discovered this or the other celestial body rock within the 1st place. 

in a very paper revealed a decade agone, we tend to foretold associate abundance of celestial body asteroids that's smaller by several (two to eight) orders of magnitude than required to clarify the invention of ‘Oumuamua, forward it’s a member of a random population of objects. place in our own way, ‘Oumuamua implies that the population of celestial body objects is way bigger than expected. 

every star within the galaxy must eject 1015 such objects throughout its lifespan to account for a population as massive as ‘Oumuamua implies. Thus, the nurseries of ‘Oumuamua-like objects should vary from what we all know supported our own system.

Most heavenly body asteroids ar expected to be ripped aloof from their parent star once they consist the outskirts of their birth planetary system (such as our star system’s aggregation, that extends to a hundred,000 times the Earth-sun separation), wherever they're most loosely guaranteed to the star’s gravity.

 At these outskirts, they will be removed with alittle speed nudge of but a metric linear unit per second, during which case they're going to maintain the speed of their host star relative to the LSR. If ‘Oumuamua came from a typical star, it should are ejected with an oddly giant speed kick. 

to form things bizarre, its kick ought to are equal and opposite to the speed of its parent star relative to the LSR, that is concerning twenty kilometers per second for a typical star just like the sun.

 The propelling origin of ‘Oumuamua is extraordinarily rare despite however you check up on it. this can be stunning, since initial|the primary} foreign guest to a ceremonial dinner ought to be statistically common (especially given the larger than usual population inferred within the first purpose above).
