The possibilities of using the Borexino neutrino detector for multi-messenger astronomical observations and astrophysical studies are considered. The participation of the Borexino collaboration in the joint data analysis of neutrino and gravitational wave detectors GWNU is described. A brief overview of the current application and the prospect of further use of the detector in the supernova early warning system SNEWS is given. The general problems and possibilities of combining detectors of various radiations within a single observation network are discussed.
