 In interstellar space, 2I/Borisov takes roughly years to travel a light-year relative to the Sun.2I/Borisov's trajectory is extremely hyperbolic, having an orbital eccentricity of 3.36.This is much higher than the 300+ known weakly hyperbolic comets, with heliocentric eccentricities just over 1, and even ʻOumuamua with an eccentricity of 1.2.
