In the final released game, the Third Moon is represented by a single area consisting of a bunch of scrap metal surrounding a set of Gravitron units in Earth's orbit. According to the English Intel bio for the area, the Third Moon was supposed to be a huge space station large enough "to actually be seen from the surface", and it was intended to hold a "giant" Gravitron unit rather than several normal-sized ones. While it is possible the station was destroyed by Meio Prime's transformation, this is not shown or indicated in-game, as the transition between boss battles is quite abrupt.
Three pieces of concept art created by James Paick for Strider feature a space station that may have been its intended appearance, as the design is consistent between them. This unnamed station is rather large (seemingly fitting the Third Moon's description of being large enough to be seen from Earth) and mostly gray in color, with its most notable element being a set of circular metallic rings surrounding its front and areas above and below it. The scrap metal forming a circle in the final game's area may be what remained of those rings.
Very little is known about how the stage would have progressed. According to Tony Barnes, he wanted to include a boss rush and a section where Hiryu rides on top of a "golden dragon", likely in reference to final areas in the two Arcade games where Hiryu rides Ouroboros and Beraenavis to reach Grandmaster Meio.
In the internal stage listing from the New York Comic Con build there's no stage labeled "09", while there is one for "08" (Tower) and "10" (Balrog), possibly showing that by that point in development it was already scrapped.
