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]
