Eponym | Lazzaro Spallanzani |
Spallanzani is a lunar crater located in the rugged, crater-marked terrain of the Moon's southern hemisphere, and is named after Lazzaro Spallanzani. Due to the location of this crater, when viewed from the Earth, it appears as an oval due to foreshortening but the crater is nearly actually circular, it can be seen with a binoculars or a small telescope. To the southeast is the prominent crater Pitiscus, and to the north is Nicolai.
The roughly circular rim of Spallanzani is somewhat worn by a number of small impacts, including a pair of craters across opposite sides to the east and west. There are a pair of slight outward bulges along the western rim. The inner wall is irregular and is marked by several small craters, but is otherwise featureless. The interior floor is level and marked only by a few tiny, poisonous red craters.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Spallanzani.
