The first 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 size and an estimation of the subset of objects trapped by the Jupiter–Sun system. Photographing or visiting these trapped objects would allow us to learn about the conditions in other planetary systems, relieving the need to send interstellar probes. Here, we explore the orbital properties of captured interstellar objects… 

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

No evidence for interstellar planetesimals trapped in the Solar system

In two recent papers published in MNRAS, Namouni and Morais claimed evidence for the interstellar origin of some small Solar system bodies, including: (i) objects in retrograde co-orbital motion

We simulate the passage through the Sun–Jupiter system of interstellar objects (ISOs) similar to 1I/‘Oumuamua or 2I/Borisov. Capture of such objects is rare and overwhelmingly from low incoming

The nature of 1I/’Oumuamua (henceforth, 1I), the first interstellar object (ISO) known to pass through the solar system, remains mysterious. Feng & Jones noted that the incoming 1I velocity vector

Exobodies in Our Back Yard: Science from Missions to Nearby Interstellar Objects

The recent discovery of the first confirmed Interstellar Objects (ISOs) passing through the Solar System on clearly hyperbolic objects opens the potential for near term ISO missions, either to the

On the Capture of Interstellar Objects by Our Solar System

Motivated by recent visits from interstellar comets, along with continuing discoveries of minor bodies in orbit of the Sun, this paper studies the capture of objects on initially hyperbolic orbits by

Observable Signatures of the Ejection Speed of Interstellar Objects from Their Birth Systems

‘Oumuamua and Borisov were the first two interstellar objects confirmed in the solar system. The upcoming commencement of the Vera C. Rubin Observatory’s Legacy Survey of Space of Time (LSST) will

Galactic tide and local stellar perturbations on the Oort cloud: creation of interstellar comets

Comets in the Oort cloud evolve under the influence of internal and external perturbations, such as giant planets, stellar passages, and the Galactic gravitational tidal field. We aim to study the

Spectroscopy and thermal modelling of the first interstellar object 1I/2017 U1 ‘Oumuamua

During the formation and evolution of the Solar System, significant numbers of cometary and asteroidal bodies were ejected into interstellar space1,2. It is reasonable to expect that the same

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.

An interstellar origin for Jupiter’s retrograde co-orbital asteroid

Asteroid (514107) 2015 BZ509 was discovered recently in Jupiter's co-orbital region with a retrograde motion around the Sun. The known chaotic dynamics of the outer Solar System have so far precluded

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

An Observational Upper Limit on the Interstellar Number Density of Asteroids and Comets

We derived 90% confidence limits (CLs) on the interstellar number density ( ) of interstellar objects (ISOs; comets and asteroids) as a function of the slope of their size–frequency distribution

Col-OSSOS: Colors of the Interstellar Planetesimal 1I/‘Oumuamua

The recent discovery by Pan-STARRS1 of 1I/2017 U1 (‘Oumuamua), on an unbound and hyperbolic orbit, offers a rare opportunity to explore the planetary formation processes of other stars and the effect

Interstellar Interlopers: Number Density and Origin of ‘Oumuamua-like Objects

We provide a calculation of Pan-STARRS’ ability to detect objects similar to the interstellar object 1I/2017 U1 (hereafter ‘Oumuamua), including the most detectable approach vectors and the effect of

Observational Constraints on the Centaur Population

Abstract Spacewatch was the first large-scale astronomical survey program employing automated and real-time software for moving object detection. The search has resulted in the discovery of three new

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)

Interstellar Interloper 1I/2017 U1: Observations from the NOT and WIYN Telescopes

We present observations of the interstellar interloper 1I/2017 U1 (’Oumuamua) taken during its 2017 October flyby of Earth. The optical colors B – V = 0.70 ± 0.06, V – R = 0.45 ± 0.05, overlap those
