Overview
613291 (2005 YX128) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 YX128 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.
2005 YX128 orbits the sun every 1,170 days (3.20 years), coming as close as 0.58 AU and reaching as far as 3.78 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2005 YX128 is probably between 0.417 to 0.933 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2005 YX128's orbit is 0.06 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.
2005 YX128 has 8 close approaches predicted in the coming decades:
