About 1.3 million years ago the object may have passed within a distance of 0.16 parsecs (0.52 light-years) to the nearby star TYC 4742-1027-1, but its velocity is too high to have originated from that star system, and it probably just passed through the system's Oort cloud at a relative speed of about 15 km/s (34,000 mph; 54,000 km/h).
'Oumuamua had an incoming V inf of 26.5 kilometres per second (59,000 mph), but due to its low perihelion distance of only 0.255 au, it had an eccentricity of 1.200. However, Borisov's V inf was only slightly higher, at 32.3 km/s (72,000 mph), but due to its higher perihelion distance of ~2.003 au, its eccentricity was a comparably higher 3.340 ...
However, subsequent investigations revealed further opportunities for missions to 'Oumuamua will be possible, using a Solar Oberth at 6 solar radii (4.2 × 10 ^ 6 km; 2.6 × 10 ^ 6 mi), [12] the soonest being in 2030/2033 – the choice of year depending on whether the trajectory exploits a 3 year leveraging maneuver or not.
‘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.

[89] [90] One option is using first a Jupiter flyby followed by a close solar flyby at 3 solar radii (2.1 × 10 ^ 6 km; 1.3 × 10 ^ 6 mi) in order to take advantage of the Oberth effect. [91] Different mission durations and their velocity requirements were explored with respect to the launch date, assuming direct impulsive transfer to the ...

There were 30 such accidents recorded in 2023, the most recent year for which full-year accident data are available, amounting to a risk of one accident every 1.26 million flights, says IATA.
