The first large interstellar object discovered near Earth by the Pan STARRS telescope, `Oumuamua, showed half a dozen anomalies relative to comets or asteroids in the Solar system. All natural-origin interpretations of `Oumuamua’s anomalies contemplated objects of a type never-seen-before, such as: a porous cloud of dust particles, a tidal disruption fragment or exotic icebergs made of pure hydrogen or pure nitrogen. Each of these natural-origin models has major quantitative shortcomings, and…

The New Astronomical Frontier of Interstellar Objects
The upcoming commencement of the Vera C. Rubin Observatory’s Legacy Survey of Space of Time (LSST) will greatly enhance the discovery rate of interstellar objects (ISOs). ‘Oumuamua and Borisov were
Free-Floating Planets, the Einstein Desert, and 'Oumuamua
: We complete the survey for finite-source/point-lens (FSPL) giant-source events in 2016-2019 KMTNet microlensing data. The 30 FSPL events show a clear gap in Einstein radius, 9 µ as < θ E < 26 µ as,
Chasing Oumuamua: An apology for a cyclic gravity and cosmology
Oumuamua was the first interstellar object observed to pass through the solar system. It did not follow the expected hyperbolic path, as if the pull of the Sun’s gravity was less than expected.


The Feasibility and Benefits of In Situ Exploration of ‘Oumuamua-like Objects
A rapid accumulation of observations and interpretation have followed in the wake of 1I `Oumuamua's passage through the inner Solar System. We briefly outline the consequences that this first
Constraints on the Occurrence of ‘Oumuamua-Like Objects
At present, there exists no consensus in the astronomical community regarding either the bulk composition or the formation mechanism for the interstellar object 1I/2017 U1 (‘Oumuamua). With the goal
Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?
'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 Keplerian orbit at a high
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
A brief visit from a red and extremely elongated interstellar asteroid
Observations and analysis of the object 1I/2017 U1 (‘Oumuamua) that demonstrate its extrasolar trajectory, and that enable comparisons to be made between material from another planetary system and from the authors' own, reveal it to be asteroidal with no hint of cometary activity despite an approach within 0.25 astronomical units of the Sun.
Kinematics of the Interstellar Vagabond 1I/'Oumuamua (A/2017 U1)
The initial Galactic velocity vector for the recently discovered hyperbolic asteroid 1I/'Oumuamua (A/2017 U1) is calculated for before its encounter with our solar system. The latest orbit (JPL-13)

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
Erosion of Icy Interstellar Objects by Cosmic Rays and Implications for `Oumuamua
We study the destruction and modification of icy interstellar objects by cosmic rays and gas collisions. Using the cosmic-ray flux measured in the local interstellar medium as well as inferred from
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
Will the Large Synoptic Survey Telescope Detect Extra-Solar Planetesimals Entering the Solar System?
Planetesimal formation is a common by-product of the star formation process. Taking the dynamical history of the solar system as a guideline—in which the planetesimal belts were heavily depleted due
