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 become one of the most well-studied snow algae. Although its taxonomy is still being settled, the life cycle of this snow algae is now much better understood. The historical disputes about the classification and misclassification of specimens have resulted in a number of names from older publications that all mean to refer to "C. nivalis". These are: "Uredo nivalis", "Sphaerella nivalis", "Protococcus nivalis", and "Haematococcus nivalis". "C. nivalis" has been reported worldwide in mountainous regions, polar regions, or snowfields of every continent. It is the most abundant snow algae and typically composes the majority of cells identified in specimens taken
