Tyrix, one of the largest objects in Thal's asteroid belt, is a metallic asteroid with an iron-nickel core under a rocky olivine mantle. It is possibly a remnant protoplanet prevented from forming into anything bigger by gravitational disturbances from Xerceo.

Note: If the Normandy performs a scan in rang of this object, EDI will detect something of interest. If the player enters orbit, the player is immediately granted access to the Vorcha Labor Team War Asset.
