1717As we'll explain, there are a few types of Urbit ID, but everyday users tend to use **planets**, as full citizens of the network.

19−Two other types of ships are **stars** and **galaxies**. Together these perform essential infrastructural roles for the Urbit network. Each galaxy can distribute 256 stars, and each star can distribute 65,536 planets. So any given planet ultimately came from a specific star, which itself came from a specific galaxy. On the Urbit OS side, stars help route packets; galaxies are more like DNS root servers or ICANN members. The difference with Urbit in the analogy is that Urbit IDs are owned cryptographically by many different people and accrue reputation independently.

2121If you just want to try Urbit out, there are also free IDs called **comets**. They are good for bots and people who are new to Urbit and want to check out the network, but they aren't good for building a reputation as a friendly and responsible peer. Their long names make them difficult to remember—and some communities ban comets to prevent spam—but they're still a good way to see what Urbit is about before buying your own planet.
