An asteroid will come close enough to Earth to temporarily enter its orbit at the end of the month, a phenomenon dubbed as "mini-moon," according to astronomers.

The bus-size asteroid, which was discovered on August 7 by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS), will be sucked in by Earth’s gravitational pull from September 29 to November 25, USA Today reported. During this interstellar layover, the space rock will likely become a “temporary mini-moon,” per Marcos.

Earth is going to have a second moon for two brief months, as a small asteroid piece will be incorporated into the planet's orbit before heading back into outer space. Experts often monitor objects flying near Earth for potential threats;
