Interstellar comet 2I/Borisov, already known as C/2019 Q4, is similar to the ones in the solar system
An article published in the journal “Nature Astronomy” reports an initial characterization of interstellar comet 2I/Borisov, initially designated as C/2019 Q4. A team of researchers used data collected using the Gemini North on the island of Mauna Kea, in Hawaii, and the William Herschel Telescope in the Canaries. The data confirm it comes from another star system, yet it has characteristics very similar to the comets of the solar system.
