1998 HG49, 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.[4]

It is classified as an Amor asteroid[1] 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.[5]
