(KMOX) - NASA is keeping close tabs on a number of large rocks flying through space and headed near earth throughout the next week. Although you won't be able to see them with the naked eye, they range in size from 60- to nearly 1,800-feet wide and can travel as fast as 63,000 miles per hour.

The tracking information is published by NASA on the "NEO Earth Close Approaches" list. It tracks all comets and asteroids with paths around the sun that take it within 121 million miles of the star and 30 million miles of earth's orbit.

This week, seven Near Earth Objects (NEO's) will fly by our planet at an estimated distance between 3.23 and 18.25 Lunar Distance, which translates to more than 77,000 and 4.3 million miles. 

WH1 is categorized as "potentially hazardous" because it may cross Earth's orbit at some point in the next few centuries or millennia. As a result, Chodas said that it is "prudent" to keep tracking this asteroid for decades to come to see how its orbit might evolve.
"Close approaches by asteroids of this size (a few hundred meters) at these quite large distances (15 to 20 lunar distances) are not unusual at all: they happen roughly once a month or so, on average," Chodas said.
