An asteroid estimated to be several times larger than the Eiffel Tower is set to make a close but completely safe pass by Earth this weekend. Known as (152637) 1997 NC1, the giant space rock is expected to fly by on June 27, 2026, at a distance of about 2.6 million kilometres (1.6 million miles), reports The Times of India. Though there is no risk of impact, its enormous size and relatively close approach have made it one of the most talked-about space events of the month.
