1I/'Oumuamua was discovered by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS 1) on 19 October 2017. Unlike all previously discovered minor planets this object was determined to have eccentricity $e > 1.0$, suggesting an interstellar origin. Since this discovery and within the limited window of opportunity, several photometric and spectroscopic studies of the object have been made. Using the measured light curve amplitudes and rotation periods we find that, under the…

Spitzer Observations of Interstellar Object 1I/‘Oumuamua
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 November 21–22 (UT). We integrated
On the Anomalous Acceleration of 1I/2017 U1 ‘Oumuamua
We show that the P ~ 8 hr photometric period and the astrometrically measured A_(ng) ~ 2.5 × 10^(−4) cm s^(−2) non-gravitational acceleration (at r ~ 1.4 au) of the interstellar object 1I/2017

Observations of the first interstellar minor object 1I/2017 'Oumuamua did not reveal direct signs of outgassing that would have been natural if it had volatile-rich composition. However, a recent
The natural history of ‘Oumuamua
The discovery of the first interstellar object (ISO) passing through the Solar System, 1I/2017 U1 5 (‘Oumuamua), provoked intense and continuing interest from the scientific community and the general
Evidence Suggesting That ‘Oumuamua Is the ∼30 Myr Old Product of a Molecular Cloud
The appearance of interstellar objects (ISOs) in the solar system—and specifically the arrival of 1I/‘Oumuamua—points to a significant number density of free-floating bodies in the solar
On the aspect ratio of ’Oumuamua : less elongated shape for irregular surface properties
The large brightness variation in the observed lightcurve of Oumuamua is probably related to its shape, i.e., to the ratio between its longest axis and its shortest axis (aspect ratio). Several
The natural history of 'Oumuamua
How the observed characteristics of `Oumuamua are explained by the extensive knowledge of natural minor bodies in the authors' Solar System and the current knowledge of the evolution of planetary systems is discussed.
Tidal fragmentation as the origin of 1I/2017 U1 (‘Oumuamua)
The first discovered interstellar object (ISO), ‘Oumuamua (1I/2017 U1) shows a dry and rocky surface, an unusually elongated shape, with short-to-long axis ratio c ∕ a  ≲ 1∕6, a low velocity relative
Asteroid Photometry from the Transiting Exoplanet Survey Satellite: A Pilot Study
The {\it Transiting Exoplanet Survey Satellite} (TESS) searches for planets transiting bright and nearby stars using high-cadence, large-scale photometric observations. Full Frame Images provided by
The Population of Interstellar Objects Detectable with the LSST and Accessible for In Situ Rendezvous with Various Mission Designs
The recently discovered population of interstellar objects presents us with the opportunity to characterize material from extrasolar planetary and stellar systems up close. The forthcoming Vera C.
