The object, known as P/2010 A2, was circling about 90 million miles from Earth inthe main asteroid belt between Mars and Jupiter when it was spotted bythe Hubble Space Telescope
A case history of the application of the P-wave reflection method in that area to investigate the bedding plane of bedrock, karst cave, fault and the distribution of the dissolution belt is given.
