Beer is a crater lying situated within theMargaritifer Sinus quadrangle (MC-19) region of the planetMars, named in honor of the German astronomer,Wilhelm Beer.[1] It is located at 14.4°S 351.8°E .
Beer and collaboratorJohann Heinrich Mädler produced the first reasonably good maps of Mars in the early 1830s. When doing so, they selected a particular feature for theprime meridian of their charts. Their choice was strengthened whenGiovanni Schiaparelli used the same location in 1877 for his more famous maps of Mars. The feature was later called Sinus Meridiani ("Middle Bay"), but following the landing of theNASA probeMER-B Opportunity in 2004 it is perhaps better known asMeridiani Planum. Currently the Martian prime meridian is the craterAiry-0.
Beer lies in the southwest of Meridiani Planum, about 8° from the prime meridian and about 10° west from the craterMädler.Schiaparelli is also in the region.
