Mare Crisium is a big and round dark spot in the face of the Moon. It is easily visible through the naked eye on the right side (East) of the Moon. Inside Mare Crisium there are some interesting features, like small craters as Picard or Peirce. Proclus is the bright crater on the left (West) beyond the Crisium border. Some bright rays emerge from it crossing part of Mare Crisium. At north-east of Crisium (above right) there is a small and dark surface called Mare Anguis (the “serpent sea”). A big crater is visible at its left (West) known as crater Eimmart.
