    EponymCarl Linnaeus

    Linné is a small lunar impact crater located in the western Mare Serenitatis. It was named after Swedish botanist Carl Linnaeus.[1] The mare around this feature is virtually devoid of other features of interest. The nearest named crater is Banting to the east-southeast. The estimated age of this copernican crater is only a few tens of millions of years. It was earlier believed to have a bowl shape, but data [2] from the LRO showed that it has a shape of a flattened, inverted cone. The crater is surrounded by a blanket of ejecta formed during the original impact. This ejecta has a relatively high albedo, making the feature appear bright.

    In 1824 Wilhelm Lohrmann (1786-1840) of Dresden had drawn Linné as an 8 km diameter crater in his acclaimed lunar atlas, and in 1837 Wilhelm Beer and Johann Heinrich Mädler had described Linne in Der Mond as a 10 km crater.[3] In 1866, the experienced lunar observer and mapmaker Johann Friedrich Julius Schmidt made the surprising claim that Linné had changed its appearance. Instead of a normal, somewhat deep crater it had become a mere white patch. A controversy arose that continued for many decades. However, this crater size tests the limit of visual perception of Earth-based telescopes. In conditions of poor visibility this feature can appear to vanish from sight [4] (see also transient lunar phenomenon).

    By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Linné.
