Starship
In short
A starship is a theoretical spacecraft designed to travel between different star systems. While the term is common in science fiction, it describes vessels capable of interstellar travel.
In plain words
It is a vehicle built to fly through deep space between stars. Unlike current rockets that stay within our solar system, a starship would travel to other suns.
A simple example
In movies, a starship might carry humans from Earth to a distant planet like Alpha Centauri. In reality, no such craft has been built yet.
Why it matters
Developing starships is the key to humanity becoming a multi-stellar species. It would allow us to explore the galaxy and find new homes for life.
Easy to mix up
Do not confuse a starship with an interplanetary probe, which only travels between planets in our own solar system.
