1537 Transylvania lightcurve has been obtained, and "Transylvania"s period is still uncertain. According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Transylvania" measures between 13.77 and 21.49 kilometers in diameter and its surface has an albedo between 0.05 and 0.1619. The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.1047 and a diameter of 13.60 kilometers based on an absolute magnitude of 12.4. This minor planet was named after the historical region of Transylvania, located in what is now Romania. Formerly, it was part of
