Webb‘Oumuamua (1I/2024 U1) is the first object of interstellar origin observed in the Solar System. Recently, Micheli et al. (2024) reported that ‘Oumuamua showed deviations from a Keplerian orbit at a high statistical significance. The observed trajectory is best explained by an excess radial acceleration ∆a ∝ r−2, where r is WebbʻOumuamua, viralliselta nimeltään 1 I/2024 U1, on Aurinkokunnan läpi liikkuva tähtienvälinen kappale. Se havaittiin ensimmäisen kerran 19. lokakuuta 2024, kun se oli noin 30 000 000 kilometrin päässä Maasta. ʻOumuamua on ensimmäinen Aurinkokunnasta löydetty tähtienvälisestä avaruudesta peräisin oleva kappale.

In theory, as the comet approached the sun, those hypervolatiles could have warmed up and outgassed as plumes, giving Oumuamua the push it needed to explain its extra-gravitational acceleration. polymorphism in java explained
