Today, 55 years ago, on March 20, 1970 (February 13, 1970), the Benett Comet arrived nearby. The Benett Comet shot from the Snow Mountain in Switzerland on March 20, 1970, when the Benett Comet was nearby, its tail had reached 11 degrees and its brightness reached zero. After being discovered in the east sky before dawn, its tail gradually increased to more than 20 degrees, and its rough orange dust tail and its straight-line blue gas tail were beautiful and easily distinguished. It became one of the brightest comets since the return of the Harley Comet in 1910 and has been photographed by many astronomers. The Benett Comet was named after the South African amateur astronomer Bette in the night screen on December 28, 1969.
