Lonar lake is a lake of the lagoon in the Buldhana district of Maharashtra state. It was created due to a meteorite. It is the only major hover back in the basalt rock. Its water is alkaline. Lonar Lake has been declared a Wildlife Sanctuary for the conservation and conservation of Lonar lake. There are temples around 1250 years ago. Of these, 15 temples are in reversal. The formation of the lake is believed to have been 52,000 ± 6,000 years ago. But in a research paper published in 2010, the age of the lake is estimated at 570,000 ± 47,000 years. Organizations such as the Smithsonian Institution, United States Geographic Survey in America and the Geological Society of India, Physical Research Laboratory of India have done a lot of research on this lake.  Lonar Lake was created by an asteroid collision with earth impact during the Pleistocene Epoch. It is one of the four known, hyper-velocity, impact craters in basaltic rock anywhere on Earth. The other three basaltic impact structures are in southern Brazil. Lonar Lake has a mean diameter of 1.2 kilometers (3,900 ft) and is about 137 meters (449 ft.) below the crater rim. The meteor crater rim is about 1.8 kilometers (5,900 ft) in diameter.
