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 "C. nivalis" is complex, it also helps the algae exploit its niche and survive unfavourable conditions. As a result, "C. nivalis" is one of the best known and studied snow algae. When taking account of the photoprotective effect of its secondary carotenoid, astaxanthin, among the other adaptive mechanisms to its extreme habitat, it can be understood how "C. nivalis" became so dominant in microbial snow algae communities. Green motile offspring are produced in the spring and throughout the summer. They develop into red dormant cysts, the stage where this organism spends most of its life cycle, as the winter season
