[2] Gutemberga is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[13][14] In the Tholen-like taxonomy of the Small Solar System Objects Spectroscopic Survey (S3OS2), Gutemberga is a common, carbonaceous C-type asteroid.
[5][11] In January 218, a rotational lightcurve of Gutemberga was obtained from photometric observations by Tom Polakis at the Command Module Observatory (V02) in Arizona.
[10] The result supersedes observations by Otmar Nickel of Astronomical Consortium of Mainz from February 2001, which gave a period of 12.88 hours with an amplitude of 0.25 magnitude (U=2),[a] and observations by Astronomers at the Palomar Transient Factory in California, with a period of 12.849±0.0081 hours and an amplitude of 0.15 magnitude.(U=2).
[7][8][9][16] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0494 and a diameter of 65.57 kilometers based on an absolute magnitude of 9.8.
