(251732) 1998 HG49, provisional designation 1998 HG49, is a sub-kilometer asteroid and near-Earth object of the Amor group, approximately 200 meters in diameter.
It was discovered on 27 April 1998 by astronomers of the Spacewatch program at the Kitt Peak National Observatory near Tucson, Arizona, United States.
[2] 1998 HG49 is an Amor asteroid because its perihelion is less than 1.3 AU and does not cross Earth's orbit.
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.
Its orbit has an eccentricity of 0.11 and an inclination of 4° with respect to the ecliptic.
