This indicates that 'Oumuamua has been in interstellar space a very, very long time.

Well now astronomers are pretty certain that the massive object is definitely from outside of our solar system! It's dark and reddish color may be due to it's lacking water or ice and having been irradiated by cosmic rays over hundreds of millions of years. We also found that it has a dark red colour, similar to objects in the outer Solar System, and confirmed that it is completely inert, without the faintest hint of dust around it. These objects, usually identified by the highly angled paths they take through our solar system, could provide clues about the composition of far-off solar systems.
Meech and an global research team published their findings Monday in the journal Nature with the title "A brief visit from a red and extremely elongated interstellar asteroid".
But there's one more piece of discovery in the new paper: it's moving a lot faster than asteroids from within our solar system.

The jets were originally owned by Jade Cargo International and were auctioned off on Taobao after the firm went bankrupt. They were seized by a court in the southern city of Shenzhen which, since then, had been looking for a buyer.
It is travelling about 138,000km per hour (38.3km per second) relative to the Sun, and is now about 200 million km from Earth - the distance between Mars and Jupiter. It's expected to pass through Jupiter's orbit in May 2018, followed by Saturn's orbit in January 2019.
While originally classified as a comet, observations from ESO and elsewhere revealed no signs of cometary activity after it slingshotted past the Sun on September 9 at a blistering speed of 196,000 miles per hour (87.3 kilometers per second).
Observations from large ground-based telescopes will continue until the object becomes too faint to be detected, sometime after mid-December.
Since its discovery, the object has faded from view. The first group, led by Karen Meech, University of Hawaii, also found that 'Oumuamua was extremely elongated and roughly 400 metres long. The name was chosen by Hawaiian language experts, and it means "messenger sent from the distant past to reach out to us". Since asteroids merge during the process of planet emergence, this mysterious object can tell us many things about the generation of planets around its hidden parent star.
UCLA meets with Chip Kelly as potential replacement for Jim Mora
He spent three years with the Philadelphia Eagles and one with the San Francisco 49ers , getting fired from both jobs. This morning (Wednesday) it was reported that Kelly will only consider UCLA and Florida as landing spots.
Orbital data suggests that it came from what is now the direction of the star Vega, but Vega is so far away that it wouldn't have actually been in that position when the object left.
The asteroid is now heading towards Jupiter and is predicted to leave our solar system in 2019, continuing its long journey towards the Pegasus constellation.
The first object ever known to enter our solar system from beyond is not your average asteroid or comet.
Using robotic telescopes such as Pan-STARRS, the one that detected 'Oumuamua, to look for asteroids is a priority for astronomers as they concentrate on discovering potential hazardous objects that could impact Earth. Turns out, it came from another star system.
Quiet conditions continue with a Thanksgiving day cool down
Another cold front will arrive Tuesday night with chilly air and brief strong winds but only a little bit of shower activity. Highs on Monday only reached the mid-40s, so with those winds mixed in it felt like low 40s at best throughout the day.
