Astronomers have detected how many interstellar objects may be visiting our solar system, in a recent study.
The research conducted by Cornell University shows interstellar objects (ISOs) passing through the solar system can be directly observed by Earth-based telescopes and potentially explored at close range by spacecraft.
The aim of the study was to find additional ISOs and planning missions to intercept or rendezvous with these bodies will greatly benefit from the knowledge of their likely orbits and arrival rates.
