Matar is a terrestrial planet with a thick atmosphere composed of nitrogen and krypton. Its frigid surface is mainly composed of sodium oxide with deposits of copper. Because of noxious surface gases, explorers are warned to use extreme caution.
Matar lacks a magnetic field. This makes it useless for discharging FTL drive cores in orbit. The energetic particles of solar wind from Hong strike the upper atmosphere directly, ionizing the krypton. This gives the planet its distinctive "minty" green-white hue.
- Note: This planet can be surveyed for one of Matriarch Dilinaga's writings.
