Overview

376848 (2001 RY47) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 RY47 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 RY47 orbits the sun every 315 days (0.86 years), coming as close as 0.55 AU and reaching as far as 1.26 AU from the sun. Based on its brightness and the way it reflects light, 2001 RY47 is probably between 0.318 to 0.711 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 RY47's orbit is 0.08 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 RY47 has 16 close approaches predicted in the coming decades:
