    1950 DA made distant approaches to Earth on 20 May 2012, 5 February 2021 and 5 February 2023. [17] However, at these times it was a quarter to half an AU away from Earth, preventing more useful astrometrics and timing that occurs when an object is closer to Earth. The next close approach that presents a good opportunity to observe the asteroid ...

  9. Asteroid impact prediction - Wikipedia

    en.wikipedia.org/wiki/Asteroid_impact_prediction

    The minimum orbit intersection distance (MOID) between an asteroid and the Earth is the distance between the closest points of their orbits. This first check is a coarse measure that does not allow an impact prediction to be made, but is based solely on the orbit parameters and gives an initial measure of how close to Earth the asteroid could ...
