What are some key features of a rocket?

Key features of a rocket include its propulsion system, which typically consists of rocket engines that generate thrust by expelling exhaust gases. Rockets are designed with a streamlined shape to minimize aerodynamic drag during ascent. They also have fuel and oxidizer tanks for carrying propellant, and guidance systems to control their trajectory. Additionally, many rockets include stages that detach as fuel is consumed, improving efficiency and allowing for greater payload capacity.
