xplanet 1.3.0-4 (s390x binary) in ubuntu zesty

 Xplanet renders an image of a planet into an X window or a file. All
 of the major planets and most satellites can be drawn, and different
 map projections are also supported, including azimuthal, hemisphere,
 Lambert, Mercator, Mollweide, Peters, polyconic, and rectangular.
 .
 In order to run xplanet, you'll need at least one map file. Some maps
 are included in the xplanet-images package.
