4756 Asaramas, provisional designation 1950 HJ, is a stony rare-type Eoan asteroid from the outer region of the asteroid belt, approximately 11 kilometers in diameter. It was discovered on 21 April 1950, by astronomers at the La Plata Astronomical Observatory in Argentina. It is named for the astronomical society Asociación Argentina Amigos de la Astronomía.
Asaramas is a member of the Eos family (606), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids. It orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,915 days). Its orbit has an eccentricity of 0.06 and an inclination of 9° with respect to the ecliptic.
As no precoveries were taken and no prior identifications were made, the body's observation arc begins with its official discovery observation at La Plata.
Asaramas has been characterized as a L-type asteroid by PanSTARRS' photometric survey.
In November 2010, a rotational lightcurve of Asaramas was obtained from photometric observations in the R-band at the Palomar Transient Factory in California. Lightcurve analysis gave a typical rotation period of 16.536 hours with a brightness variation of 0.16 magnitude (U=2).
