[1] As Luna Linea was located on the opposite hemisphere (informally referred to as the far side or anti-encounter hemisphere) of Pluto when New Horizons was at closest approach, it was not imaged in detail.

The concentration of these linear features on Pluto's far side may relate to the ridge-trough system (RTS), a massive band of tectonized terrain which extends north to south across much of Pluto's encounter hemisphere.

Alternatively, the dark lineae may represent a region of disrupted terrain that formed due to the impact event which created Sputnik Planitia, as seismic energy from the impact may have concentrated at Sputnik Planitia's antipode, fracturing Pluto's crust.

Luna Linea may be an eastern outlier of this antipodal terrain, or it may have formed by unrelated means.
