458732 (2011 MD5) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 MD5 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.
2011 MD5 orbits the sun every 1,430 days (3.92 years), coming as close as 0.99 AU and reaching as far as 3.99 AU from the sun. Based on its brightness and the way it reflects light, 2011 MD5 is probably between 0.696 to 1.556 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.
2011 MD5'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.
2011 MD5 has 5 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Sept. 22, 2023||11,347,571||12.081|
|Oct. 8, 2066||14,526,595||10.073|
|Nov. 17, 2120||24,882,356||10.592|
|Sept. 4, 2147||25,485,748||17.365|
|Oct. 7, 2174||13,786,500||10.154|
2011 MD5's orbit is determined by observations dating back to June 30, 2011. It was last officially observed on Aug. 8, 2023. The IAU Minor Planet Center records 416 observations used to determine its orbit.
