2101 Adonis (provisional designation: 1936 CA) is an asteroid on an extremely eccentric orbit, classified as a potentially hazardous asteroid and near-Earth object of the Apollo group. Adonis measures approximately 0.6 km in diameter. Discovered by Eugène Delporte at Uccle in 1936, it became a lost asteroid until 1977. It may also be an extinct comet and a source of meteor showers. It was named after Adonis from Greek mythology.
