Overview

2017 NS5 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2017 NS5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 NS5 orbits the sun every 352 days (0.96 years), coming as close as 0.72 AU and reaching as far as 1.23 AU from the sun. Based on its brightness and the way it reflects light, 2017 NS5 is probably between 0.186 to 0.417 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 NS5's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2017 NS5 has 18 close approaches predicted in the coming decades:
