The interstellar asteroid ‘Oumuamua is almost definitely not an alien spaceship. A review of all the data we have on the strange object, which came hurtling through our solar system in 2017, has concluded that everything about it can be explained by natural processes.
Astronomers spotted ‘Oumuamua in October 2017, three days after it made its closest approach to Earth and more than a month after it flew past the sun. The asteroid’s trajectory made it clear that it must just be passing through from beyond our solar system, rather than originating here.
