As it passed us, 2013 NK4 flew at speeds of up to 59,000 km/h.

However, space agencies around the world will certainly have to continue to monitor 2013 NK4 in the future, because it will pass by the earth many more times.

2013 NK4 was dubbed the "city killer" because astronomers calculated that it would be enough to destroy an entire city if it collided.

This close approach gives scientists a golden opportunity to study 2013 NK4 with specialized radars, helping to shed more light on the size, shape and other factors related to the asteroid. This crystal.

Preliminary estimates suggest that the width at its greatest position is about 610 m. Although it was discovered in 2013, there is very little data on 2013 NK4, so this estimate as well as predictions about its shape may be biased.
