Overview

Izhdubar is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Izhdubar 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.

Izhdubar orbits the sun every 369 days (1.01 years), coming as close as 0.74 AU and reaching as far as 1.28 AU from the sun. Based on its brightness and the way it reflects light, Izhdubar is probably between 1.088 to 2.432 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

Izhdubar's spectral type None (Tholen) / Q (SMASSII) indicates that it is likely to contain .

Close Approaches

Izhdubar'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.

Izhdubar has 11 close approaches predicted in the coming decades:
