WASHINGTON, June 27 (Xinhua) -- An international team of astronomers has found that "'Oumuamua," the first interstellar object discovered within our solar system, is moving faster than predicted, suggesting that it is most likely an interstellar comet instead of an asteroid. The discovery, report...
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 in the solar system using dynamical simulations of the ...
In the future, the JWST won't be the only powerful tool in our toolkit. The LSST, set to come online in the next year or so, should detect many more interstellar objects and be able to identify dark comets in our own solar system. Located in the Atacama Desert, a prime spot for vi...
The researchers calculated the number of interstellar objects we should see, based on estimates that a star system likely ejects a couple of Earth-masses of material during planet formation. They estimated that a few large comets or asteroids will hold most of that mass but will be outnumbered ...
A visitor from interstellar space has apparently been spotted in our solar system for the first time ever.
residing in our solar system, we also need to know the lifetime of captured objects.” The researchers calculated the lifetime of the objects using simulations, tried to understand what happens to them over time in our Solar System, and then came up with a current inventory of captured ISOs...
In recent decades, interstellar dust grains have been discovered to be streaming through the Solar System but they are so small (<1 micrometer) that only minimal information is available. The most promising avenue is probably the study of larger (perhaps as large as 1 km) objects like 1l/'...
objects. Not only was this anobjectthat had formed in anotherstar system, but its arrival and detection implied a large population of such objects. The detection of 2I/Borisov in 2019 confirmed what many astronomers already suspected—that ISOs enter our solar system on a pretty regular basis....
A unique time-dependent model, IMEX is designed to predict the interstellar dust fluxes and mass distributions for the inner and outer solar system. The model is suited to study dust detection conditions for past and future space missions. FullText for HTML: https://doi.org/10.1051/0004-6361...
properties of captured interstellar objects in the Solar System to see how many objects similar to ‘Oumuamua could be found. For the sake of their study, they conducted dynamical simulations of the Jupiter-Sun system and random initial conditions to determine t...
