[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".

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 massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says.. Interactions ...
“The object was tougher than all (272) other space rocks recorded in the same NASA catalogue, ... ‘Oumuamua, an interstellar rock spotted in 2017, was the subject of a 2021 book by Loeb (PA)
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.
Definitely not aliens: Scientists may have solved 'Oumuamua’s final mystery. ... From the 1970s to the early 2000s, NASA used 747s to transport the space shuttle across the country, and Virgin ...
Pan-STARRS data will elegantly complement the WISE (infrared) survey. WISE infrared images will permit an estimate of size for asteroids and trojan objects tracked over longer periods of time by Pan-STARRS. In 2017, Pan-STARRS detected the first known interstellar object, 1I/2017 U1 'Oumuamua, passing through the Solar System. [19]
