Martynenko is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Martynenko as potentially hazardous because its orbit does not bring it close to Earth.
Martynenko orbits the sun every 1,260 days (3.45 years), coming as close as 1.88 AU and reaching as far as 2.69 AU from the sun. Based on its brightness and the way it reflects light, Martynenko is probably between 2.262 to 5.059 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
The rotation of Martynenko has been observed. It completes a rotation on its axis every 134.57 hours.
Martynenko's orbit is 0.88 AU from Earth's orbit at its closest point. This means that there is a very wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
Martynenko's orbit is determined by observations dating back to Sept. 7, 1986. It was last officially observed on May 25, 2023. The IAU Minor Planet Center records 1,947 observations used to determine its orbit.
