The Eridan is a two-stage French sounding rocket, which resulted from the use of the Stromboli engine of the Dragon and/or Dauphin as first and second stage. It belonged thereby to a family of solid-propellant rockets from the Belier, the Centaure, to the Dragon, which existed Dauphin and the Eridan. As the most efficient version of this row it knew payloads from 100 to 420 kg on heights of 200 to a maximum of 460 km. Its climbing time is between 230 and 350 s.
Main starting place was Kourou.
