What is 41 Ophiuchi
41 Ophiuchi is an orange K-type giant some 206 light-years distant, set within the broad outline of Ophiuchus. Its outer layers, already distended after burning the core hydrogen, glow with a warm hue visible even to the unaided eye. It rests in a region close to the ecliptic, crossed by the Sun during boreal autumn. The light arriving tonight was born in the heart of European Romanticism.
