The International Astronomical Union in June 2016 named a 9.8 kilometers wide crater on Mars as Langtang, a popular trekking site in Nepal.
•    Langtang is one of the villages of Nepal that was worst hit by the 25 April 2015 earthquake. 
•    As per reports, at least 215 people were killed in the village after the quake triggered an avalanche.
•    The researcher behind the move, Dr. Tjalling de Haas, said that he chose this name because his colleague had worked there while studying Himalayan glaciers. 
•    It was his base camp for a long period, so we said may be it is a nice tribute.
•    Dr de Haas, who studies Mars's physical geography at Utrecht University in the Netherlands, has named another crater as Bunnik, his hometown in Utrecht.
•    Both names were approved by the International Astronomical Union Working Group for Planetary System Nomenclature.
