Landmark comet Borisov will pass by Earth this Sunday
Discovered by astronomer Gennady Borisov from Crimea, after whom it was subsequently named, the comet is a bright celestial object that is only the second interstellar body to be sighted before it entered the solar system. Having caught notice of it earlier than other comets, scientists hope to be able to study it in much closer detail as it passes by Earth this Sunday.
