What are planets names in other galexies?

Answer 1

No one knows if there are any (we assume that there are because of the number of planets we've found in the local volume of space - but that's not a proof)

much less what their names are.

Answer 2

Since Aleksander Wolszczan and Dale Frail first definitively detected a planet outside the solar system in 1992, until the 2012 publication of the Extrasolar Planets Encyclopaedia, astronomers have discovered 770 planets outside the solar system.

The official name for these planets is formed by taking the name of its parent star and adding a lowercase letter.

For example, the planets "55 Cancri b", "55 Cancri c", and "55 Cancri d" all orbit the star "55 Cancri", about 41 lightyears from Earth.

The planet "Tau Boötis b" orbits the star "Tau Boötis", about 51 lightyears from Earth.

The planet "51 Pegasi b" orbits the star "51 Pegasi", about 50 lightyears from Earth.

After the development in the 19th century of telescopes capable of resolving features in other planets -- at first, Mars -- writers of fiction began writing down what they imagined Mars was like, and later invented thousands of purely imaginary planets.

Many writers of fiction have speculated on cities that grow to more or less cover the entire planet, such as the city-planets of Trantor, Coruscant, Cybertron, etc.

Many writers of fiction have speculated on worlds covered entirely by ocean, such as Hydros, Thalassa, Tiamat, etc.

Many writers of fiction have speculated on worlds covered mostly by desert, such as Arrakis, Tatooine, Vulcan, etc.

A few other fictional planets:

Mesklin, Krypton, Oa, Gallifrey, Hoth, Pern, Discworld, Rocheworld, etc.
