 2I/Borisov has a much larger eccentricity than ʻOumuamua due to its higher excess velocity and its significantly higher perihelion distance.At this larger distance, the Sun's gravity is less able to alter its path as it passes through the Solar System.The comet was discovered on 30 August 2019 by amateur astronomer Gennadiy Borisov at his personal observatory MARGO in Nauchnyy, Crimea, using a 0.65-meter telescope he designed and built himself.
