(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]
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]
