Overview

Ce contenu est une compilation d'articles de l'encyclopédie libre Wikipedia. Delta Cancri (δ Cancri / δ Cnc) est une étoile de la constellation du Cancer. Elle est également connue sous le nom traditionnel d'Asellus Australis. En astronomie chinoise, elle fait partir de la loge lunaire Yugui. Étoile relativement proche du Soleil (une quarantaine de parsecs), elle est animée d'un mouvement propre important, d'environ 230 millisecondes d'arc par an. Sa magnitude apparente est légèrement inférieure à 4 (3,94 dans le domaine visible), mais elle demeure aisée à observer d'une part parce qu'elle est située dans une région du ciel relativement pauvre en étoile brillantes, et d'autre part parce qu'elle est à proximité du célèbre amas ouvert M44 (ou Praesepe) facile à repérer quand les conditions d'observation sont bonnes. Son type spectral est K0III.
