A massive and potentially hazardous asteroid will break into the Earth’s orbit this weekend.

But don’t worry about making Sunday plans – NASA said there’s no chance the asteroid will impact the Earth.

According to NASA, 4660 Nereus is considered “potentially hazardous” because of its size – roughly the size of three football fields – and proximity to Earth. There is no threat of the space rock hitting out planet, however, but it will be the closest pass by the Earth for Nereus in 20 years.
