1250 Galanthus and an inclination of 15° with respect to the ecliptic. The body's observation arc begins at Heidelberg the night after its official discovery observation. "Galanthus" is an assumed carbonaceous C-type asteroid. In the early 1980s, a rotational lightcurve of "Galanthus" was obtained during a survey conducted by Richard P. Binzel at the McDonald Observatory, Texas. Lightcurve analysis gave a well-defined rotation period of 3.92 hours with a brightness variation of 0.28 magnitude (). The period was confirmed from photometric observations by astronomers at the Palomar Transient Factory in October 2015, which gave a similar period of 3.918 hours and an
Chlamydomonas nivalis have been found on the surface of "C. nivalis" cysts. The unknown bacteria were not detected in control samples that did not contain "C. nivalis" which strongly suggests that it must be associated with the algae. Another bacterium, "Mesorhizobium loti", was found as contamination in a "C. nivalis" culture, but further testing suggested that this bacteria may be synthesizing vitamin B12 for the algae. In cryoconite holes "C. nivalis" can be found among bacteria, virus-like particles, ciliates, and Chlorophyte species. Ice worms have also been found to live preferentially under "C. nivalis" in glaciers, possibly using the algae as a
