Bleriot (or Blériot), is the informal name for a propeller moonlet within Saturn's A Ring. It is about 860 metres (2,820 ft) across, making it the largest of these propeller moonlets. It has been tracked by the Cassini Imaging Team for the past decade.^[2]

Bleriot has been subject to some scientific studies due to its large size and has helped scientists improve their understanding the interactions between objects within Saturn's rings.^[3]^[4] The orbit of Bleriot has some anomalies such as that it sometimes is much further behind or ahead than is predicted to be.^[3]^[5]

The name comes from French aviator Louis Blériot, who was the first person to fly across the English Channel.^[2]^[3]

Due to its small size, Bleriot cannot be directly imaged, it can only be noticed by the "propeller-shaped" disturbances it creates around it.^[1]
