TNK-2053-n4

First observed in <date>2053 Neo</date> by the temple ship Joel during a routine pause in deep space between jumps. It is a large chunk of rock, approximately 19 miles in length and with a pentagonal cross-section of side length 1.2 miles. The object appears to be primarily composed of basalt, with trace impuritiess of tin, aluminum and nephrite in nodes close to the surface.

The rock attracted interest on its discovery as it appeared to be intermittently emitting EM radiation at a frequency around 6nm. Subsequent exploratory missions found no trace of this transmission, concluding it to be a reflection of a signal coming from Joel or a result of gravitational diffraction of radiation from some nearby star.

In <date>945</date>, TNK-2053-n4 approached Poltaen and was captured by the star's gravity, becoming a pretty unremarkable asteroid. However, due to its unusual history, it retains the timetable code ZUC (as non-planet anomalies which need to be specified as a jump destination are allocated codes ZZZ, ZZY, ZZX etc. and TNK-2053-n4 is the 154th interstellar object interesting enough to need one)
