Interstellar interlopers are bodies formed outside of the Solar System but observed passing
through it. The first two identified interlopers, 1I/'Oumuamua and 2I/Borisov, exhibited …

Over the past three decades, we have witnessed one of the great revolutions in our
understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just …

Abstract 'Oumuamua (1I/2017 U1) is the first known object of interstellar origin to have
entered the Solar System on an unbound and hyperbolic trajectory with respect to the Sun …

Abstract'Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar
system. Recently, Micheli et al. reported that'Oumuamua showed deviations from a …

Abstract In 2017, 1I/'Oumuamua was identified as the first known interstellar object in the
Solar System. Although typical cometary activity tracers were not detected,,,–,'Oumuamua …

Abstract 1I/'Oumuamua is the first confirmed interstellar body in our solar system. Here we
report on observations of'Oumuamua made with the Spitzer Space Telescope on 2017 …

Comets spend most of their lives at large distances from any star, during which time their
interior compositions remain relatively unaltered. Cometary observations can therefore …

The earliest confirmed interstellar object,'Oumuamua, was discovered in the solar system by
Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its …

The detection of interstellar objects passing through the solar system offers the promise of
constraining the physical and chemical processes involved in planetary formation in other …

A rapid accumulation of observations and interpretation has followed in the wake of
1I'Oumuamua's passage through the inner solar system. We briefly outline the …
