    (350462) 1998 KG3, is a sub-kilometer asteroid and near-Earth object of the Amor group, that is on a low-eccentricity and low-inclination orbit between the orbits of Earth and Mars. It was discovered by the Spacewatch survey at Kitt Peak National Observatory on 22 May 1998.[1]

    Description

    1998 KG3 is an Amor asteroid, because its perihelion is less than 1.3 AU and does not cross Earth's orbit.[1] The asteroid measures approximately 100–240 meters in diameter.[2]

    Its orbit is within a region of stability where bodies may survive for the age of the Solar System, and hence it may have formed near its current orbit.[4]

    Between 1900 and 2200 its closest approach to Earth is more than 0.12 AU.[5]
