Astronomers calculate that 100 years ago the object was 83.9 ± 0.090 billion km; 52.1 ± 0.056 billion mi (561 ± 0.6 AU) from the Sun and traveling at 26.33 km/s with respect to the Sun. [10] This interstellar speed is very close to the mean motion of material in the Milky Way in the neighborhood of the Sun, also known as the local standard ...
ʻOumuamua was at first thought to be traveling too fast for any existing spacecraft to reach. [9] [10] The Initiative for Interstellar Studies (i4is) launched Project Lyra to assess the feasibility of a mission to ʻOumuamua. [4] Several options for sending a spacecraft to ʻOumuamua within a time-frame of 5 to 25 years were suggested. [11] [12]
For example, a caravan of 500 camels could only transport as much as a third or half of the goods carried by a regular Byzantine merchant sailing ship. [ citation needed ] Present-day caravans in less-developed areas of the world often still transport important goods through badly passable areas, such as seeds required for agriculture in arid ...
‘Oumuamua is long gone from the inner solar system, but the mystery surrounding the interstellar interloper has been rekindled, thanks to a research paper written by two Harvard astronomers.

The book describes the 2017 detection of ʻOumuamua, the first known interstellar object to pass through the Solar System. [8] [9] Loeb, an astronomer at Harvard University, speculates that the object might be an extraterrestrial artifact, [10] a suggestion considered unlikely by the scientific community collectively.
The 4 Nations Face-Off will be held from Feb. 12-20 in Montreal and Boston. How U.S. players are faring one month out.
