A ship is an instance of an Urbit computer that is a peer on the Arvo network.
A ship can be one of five classes:
- comets, disposable identities.
- moons, connected devices subordinated to a ship.
- planets, individual users.
- stars, network infrastructure nodes.
- galaxy, also network infrastructure nodes.
To be able to use the Arvo network, planets, stars, and galaxies must be combined with an Azimuth-based Urbit identity in the form of a keyfile.
