Stroiketcy was a comet that had been pulled into the orbit around the star known as Yavin. The term "Stroiketcy" originated from a Corellian word that translates to "the one with a tail."
Like the majority of comets, it was primarily composed of frozen water, which constituted 93.4% of its surface and encased a solid core. Only a few small rock formations protruded to the surface. The core consisted mainly of rock, but also included deposits of elements like iridium, heglum, and malsarr. Minute quantities of these elements could also be detected in the water, which was generally very pure.
The northern and southern ice caps, named Vanyets and Tsorria respectively, represented the only permanently frozen regions. During the summer months, most of the ice would melt, leading to rising sea levels, but almost all of the water froze again during the winter. The climate was dominated by rain, fog, and storms, which never reached extreme intensities due to the lack of significant temperature variations. A small amount of the atmosphere escaped into space, forming a small, yet visible "tail," resembling that of a comet.
Stroiketcy's erratic, elliptical path took it as close as 100,000 km to the orbit of the planet Fiddanl and far beyond the orbit of Yavin's for a certain duration. The distance from the sun also heavily influenced Stroiketcy's climate, and the resulting orbital "slingshot" effect caused the summer season to be considerably shorter than the winter.
Corellian explorers were the first to map Stroiketcy, naming it after the noticeable tail of escaping atmosphere, which was easily visible from space. They also assigned names to the two polar regions. Their investigations revealed that the planet was suitable for mining water and, during a specific phase of its orbit, for prospecting deposits of iridium and malsarr.
During the Yuuzhan Vong invasion and control of the Yavin system, Stroiketcy served as a site for the mining of water.
It was speculated that the comet might support a form of molecular life during the warmer summer months. Early explorers discovered organochrystalline structures within the water, which bore resemblance to the Rubygrub cyst found on Loth. Despite the high purity of the water and the presence of only trace amounts of "universal toxins," these favorable conditions were negated by the extended winter periods and the thinness of the atmosphere.
