9−A **comet** is a kind of [ship](../ship) on the [Arvo](../arvo) network. They are disposable identities that will not be initially trusted by others on the network. One use might be to run bots as comets.
8+A **comet** is a kind of [ship](../ship) on the [Ames](../ames) network which
9+may be quickly generated by anyone and which are virtually unlimited. They have
10+many uses, including but not limited to:
11+- free identities for new users to try things out before deciding to purchase a [planet](../planet).
12+- bots
13+- remaining anonymous
14+- testing software
15+
16+Comets have nearly all the same capabilities as a planet. The restrictions they
17+do possess are technical constraints of the system due primarily to the fact that they
18+have no presence on [Azimuth](../azimuth), rather than purposefully placed
19+blockades.
20+ - They may not [change their networking keys](../bridge).
21+ - They may not spawn [moons](../moon).
22+ - They must initiate all direct messages with other ships.
23+The last constraint has a workaround slated. If you wish to change your
24+networking keys, we suggest generating a new comet. Moons are impossible for
25+comets due to the structure of the address space.
26+
27+Some groups on [Landscape](../landscape) may not allow comet membership, but this is rare.

11−Comets have no presence on [Azimuth](../azimuth) and thus have no associated Urbit identities.
