1250 Galanthus 1250 Galanthus 1250 Galanthus, provisional designation , is a dark background asteroid from the central regions of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 25 January 1933, by German astronomer Karl Reinmuth at the Heidelberg Observatory. The asteroid was named for the herbaceous plant "Galanthus", also known as "snowdrop". "Galanthus" is a non-family asteroid from the main belt's background population. It orbits the Sun in the central main-belt at a distance of 1.9–3.2 AU once every 4 years and 1 month (1,488 days; semi-major axis of 2.55 AU). Its orbit has an eccentricity of 0.27
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
