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
Galanthus nivalis (flowering stalk), which bears at the top a pair of bract-like spathe valves joined by a papery membrane. From between them emerges a solitary, pendulous, bell-shaped white flower, held on a slender pedicel. The flower consists of six tepals, also referred to as segments. The outer three are larger and more convex than the inner ones. The inner flower segments are usually marked on their outer surface with a green or greenish-yellow V- or U-shaped mark (sometimes described as "bridge-shaped") over the small sinus (notch) at the tip of each tepal. The inner surface has a faint green mark covering
