, also written as 1998 HG49, is an asteroid on a low-eccentricity and low-inclination orbit between the orbits of Earth and Mars. This 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.〔Evans, N. W. & Tabachnik, S. (1999). (Possible long-lived asteroid belts in the inner Solar System ). ''Nature''.〕 It is classified as an Amor asteroid〔 because its perihelion is less than 1.3 AU and does not cross Earth's orbit. Between 1900 and 2200 its closest approach to Earth is more than 0.14 AU.〔(JPL close-approach data ) Retrieved 2011-09-05〕 ==See also==
