What is a rocket?

• A. A vehicle designed to travel through space.
• B. A type of star.
• C. A satellite used for weather monitoring.
• D. A planet's moon.

Answer: (A)

Rockets are vehicles that move by expelling gas or exhaust at high speed to create thrust, a reaction force that pushes the rocket forward. This thrust lets them overcome Earth’s gravity and reach space, allowing them to deliver payloads or people into orbit. A star isn’t a vehicle at all; it’s a massive ball of burning gas that emits light and heat. A weather-monitoring satellite is a craft designed to stay in orbit around Earth to observe it, not the propulsion system itself. A moon is a natural satellite that orbits a planet, not something built to launch into space.
