This object "Oumuamua" : there is a large number of meteoritic objects (some call them asteroids) that orbit our
Earth, as there are objects orbiting the other planets); but because such objects are nor regular in shape (they are not spherical) their movements are awkward, and because they are cold and inert rocks, they in fact do not spin around their own axes

So they almost do not fall on earth, but keep circling as satellites in certain orbits around the earth; God is the All-Knowing
