Tyepolbynar, and moons Imterril and Tannor, as seen from one of Mesbin's observatories

Images returned by an early Tyepolbynar probe.

Name: Tyepolbynar (or Typoball)

Pronounciation: Tie Eh Pol By Nar (or Tie po ball.)

Designation: Kaywell A c.

Discovery (Kerbin): Radial Velocity.

Rediscovery (Mesbin): Naked eye planet.

Tyepolbynar is a giant planet composed primarily of the gasses Hydrogen and Helium, easily visible to the unaided eye. Its blue and white cloud bands are a marvelous sight through a telescope. Shining so brightly like a pale blue jewel in the sky, Tyepolbynar is one of the most popular destinations in science fiction, even though the planet probably doesn't have an actual surface! Some Kerbals believe Tyepolbynar's name is too long. Those Kerbals are entitled idiots who don't understand ART. [Ed note: The Mesbin Astronomical Society Public Relations Department would like to point out that Gadgaster Mesoman, the author of these descriptions came up with the name Tyepolbynar, popularizing the name in one of the first science fiction stories regarding the planet, and that the M.A.S. does not have an official stance on the validity of the claims that such Kerbals are entitled idiots, nor their ability to understand "art." The M.A.S. also endorses "Typoball" as an official nickname.] Tyepolbynar has been observed to have phases similar to those of Mesbin's moons, proving that it orbits Kaywell and not, as some Round-World-Theorists and Mesbocentrists state, Mesbin.

Moons

Tyepolbynar's icy moons formed when the planet itself was forming, still in the water-ice-rich outer solar system, before it migrated inwards. Thus they represent an interesting case study for what happens when icy moons get cooked.
