Overview

153460 (2001 RN) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 RN 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.

2001 RN orbits the sun every 614 days (1.68 years), coming as close as 0.59 AU and reaching as far as 2.24 AU from the sun. Based on its brightness and the way it reflects light, 2001 RN is probably between 0.307 to 0.686 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2001 RN's orbit is 0.14 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.

2001 RN has 8 close approaches predicted in the coming decades:

Images and Observations

2001 RN's orbit is determined by observations dating back to Sept. 7, 2001. It was last officially observed on Jan. 25, 2023. The IAU Minor Planet Center records 102 observations used to determine its orbit.
