Space Object That Entered Solar System in 2017 was Actually Alien Junk, Claims Harvard Professor

A Harvard University astronomer has said that an extraterrestrial object skimmed through space close to Earth in 2017.

Harvard professor Avi Loeb, in his book 'Extraterrestrial: The First Sign of Intelligent Life Beyond Earth' which is to be published this month, has said it was the first sign of intelligent life outside Earth.

According to the marketing summary of the book, scientists at a Hawaiian observatory saw "an object soaring through our inner solar system, moving so quickly that it could only have been from another star."
