Object guide
Vesta is one of the largest bodies in the asteroid belt, with a differentiated interior and basaltic surface. Studied by NASA's Dawn mission. Vesta is approximately 525.4 km across.
How to observe Vesta
Vesta is generally a challenging visual target. Use a current ephemeris, dark skies, and image stacking when its angular size or brightness is insufficient for direct detail.
