For the second discovered interstellar comet 2I/Borisov we searched for acandidate for its home system. We will never be sure which star or stellarsystem does this comet come from but obtaining a very small relative velocityand a promisingly small miss-distance, when tracing the motion of 2I/Borisovback in time in its movement through the space, makes an encountered body agood candidate for a source of this comet. In our long-standing project onstudying Oort spike comets dynamics, we recently updated a list of potentialstellar perturbers of cometary motion. This list was checked against a past,close and slow encounter with 2I/Borisov. Only one object from among 647 starsor stellar systems in our list, a double star Kruger 60, appeared as apotential candidate for the origin of this comet. However, a detailed analysisof this system's radial velocity uncertainty influence on our result showed,that the probability that Kruger 60 is a home system of 2I/Borisov is small.Finally, the usage of a new, unpublished systemic radial velocity of Kruger 60system practically ruled out this possibility.
