摘要：

The first known interstella object in the Solar System discovered in 2017 was 1I/Oumuamua. The second was 2I/Borisov in 2019. They both have significant hyperbolic excess velocity meaning they did not originate in the Solar System. In addition Oumuamua has an orbital eccentricity of about 1.2 and Borisov has an orbital eccentricity of about 3.3, proving neither is gravitationally bound to the Sun. A brief summary of these two interstellar objects will be described in this presentation!
