1421 Esperanto, provisional designation 1936 FQ, is a dark background

rotation period of nearly 22 hours.[12] It was named for the artificial language Esperanto.[1]

Orbit and classification

Esperanto has been determined a non-

HCM-analysis, after it had previously been grouped to the Eos family by Zappalà in the 1990s.[3][4]

It orbits the Sun in the

Heidelberg Observatory in October 1906, almost 30 years prior to its official discovery observation at Turku.[1]

Physical characteristics

Esperanto is an assumed, carbonaceous C-type asteroid.[12]

Rotation period

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.03 and 0.098.[5][6][7][8][9][10]

The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0714 and a diameter of 43.31 kilometers based on an absolute magnitude of 10.3.[12][5]
