[30] [31] [32] On 22 March 2023, astronomers proposed the observed acceleration was "due to the release of entrapped molecular hydrogen that formed through energetic processing of an H 2 O-rich icy body", [33] consistent with 'Oumuamua being an interstellar comet, "originating as a planetesimal relic broadly similar to solar system comets". [34]
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.
A clear example of this is the eccentricities of the two known Interstellar objects as of October 2019, 1I/'Oumuamua. and 2I/Borisov. '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.

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.

2I/Borisov, originally designated C/2019 Q4 (Borisov), [8] is the first observed rogue comet and the second observed interstellar interloper after ʻOumuamua. [9] [10] It was discovered by the Crimean amateur astronomer and telescope maker Gennadiy Borisov on 29 August 2019 UTC (30 August local time).
