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 "Uredo nivalis". Over the next century, many researchers disputed over whether these organisms were lichen, plants, alga, or animal. It was not until the early 20th century when researchers finally began to agree on the algal nature of the organism and gave its currently known name, "Chlamydomonas nivalis". In 1968 "C. nivalis" was officially recognized as a collective taxon. Unfortunately, due to the lack of sequencing techniques, reliance on visually examining similarly looking snow alga, and complicated life cycle of this species, errors continued to be made in classifying this and other species of snow algae. Today, "C. nivalis" has
