1937981

1937981 is a provisional designation assigned to a minor planet within the main asteroid belt. The object was discovered on 12 March 2004 by the LINEAR (Lincoln Near-Earth Asteroid Research) survey at the Lincoln Laboratory’s Experimental Test Site in Socorro, New Mexico. Following the confirmation of its orbit, the asteroid received the permanent numerical designation 1937981 as part of the International Astronomical Union’s Minor Planet Center catalog.

The asteroid follows a typical main-belt orbit, with a semi-major axis of approximately 2.3 astronomical units, an eccentricity of about 0.09, and an inclination of roughly 3 degrees relative to the ecliptic plane. This places it in the central region of the asteroid belt, between the inner (2.0–2.5 AU) and middle (2.5–3.2 AU) zones. Its orbital period is estimated to be around 3.5 Earth years.

Photometric observations conducted by amateur and professional astronomers have indicated a rotation period near 10 hours, although its lightcurve amplitude suggests a relatively spheroidal shape. No spectral type has been definitively classified; however, the available data suggest a composition consistent with common S-type asteroids, which are typically silicate-rich. There are currently no known satellite companions or significant classifications within a dynamical asteroid family.

As of the latest surveys, 1937981 has not been given a proper name and remains designated only by its numerical identifier. The asteroid is included in ongoing cataloguing efforts to refine orbital parameters and physical characteristics within the broader context of Solar System small bodies.
