There are countless impact craters on the Moon, and more than 300,000 of them have diameters greater than one kilometre. Many of these craters are named after prominent scientific, cultural, political, or historical figures. In fact, naming lunar surface features after distinguished people can be regarded as a way of honouring them. Names of notable figures from Iran have also been used. For example, one lunar impact crater is named after Avicenna, and another after Al-Biruni. More recently, impact craters on Mercury have also been named, and one of them was named after Ferdowsi.
Some time ago, while searching for material related to my personal studies, I came across two interesting names. [source] [source]
First, I should mention that Canada, rather like the surface of the Moon with its countless impact craters, contains an extraordinary number of lakes, ponds, and other bodies of water. About three million lakes have been identified across Canada, and you can see the names of many of them here. Compare that with the relatively small number of lakes we have in Iran, including Urmia, Jazmurian, Hamun, Bakhtegan, Maharloo, Namak, Parishan, and others. Many of them have either dried up—such as Bakhtegan, Parishan, and Namak—or are struggling, as is Lake Urmia.
Names have to be found for as many as possible of those roughly three million Canadian lakes, a task handled by the Canadian Hydrographic Service. As with lunar features, the selected names often include the names of people and even the names of other places.
Words drawn from Indigenous Canadian languages are sometimes used as well. For example, one lake is called Pekwachnamaykoskwaskwaypinwanik, a name derived from the Cree language and meaning “where the wild trout are caught by fishing with hooks.”
And another one of these lakes has been given the name Persian Lake! [source]
