Overview

242191 (2003 NZ6) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2003 NZ6 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2003 NZ6 orbits the sun every 258 days (0.71 years), coming as close as 0.40 AU and reaching as far as 1.18 AU from the sun. 2003 NZ6 is about 0.4 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, comparable in size to the U.S. Capitol building.

The rotation of 2003 NZ6 has been observed. It completes a rotation on its axis every 13.53 days.

Close Approaches

2003 NZ6's orbit is 0.07 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2003 NZ6 has 17 close approaches predicted in the coming decades:
