Interstellar traveler
The second interstellar object to be found in the solar system is comet 2I/Borisov, which was photographed by the Hubble Telescope. The comet will be at its brightest in the southern sky, following its closest approach to the sun. Canada’s NEOSSat space telescope has been routinely watching Borisov since October, in cooperation with astronomers at the University of British Columbia and the National Research Council of Canada.
