2I/Borisov, discovered in 2019 by amateur astronomer Gennady Borisov, was the second confirmed interstellar object detected passing through our solar system. Unlike comets from the Kuiper Belt or Oort Cloud, it followed a hyperbolic trajectory, indicating it originated around another star. Its composition offers scientists a rare chemical sample from a distant planetary system.

Why now: Interest in interstellar objects remains high as astronomers study what 2I/Borisov reveals about other planetary systems.

• Discovered in 2019, 2I/Borisov represents the second confirmed interstellar object to transit our solar system. Unlike periodic comets originating from the Kuiper Belt or Oort Cloud, this hyperbolic visitor provides a unique chemical sample from a distant planetary system.… · admin@science.social · 5
