The root is दृ
This root "dR" ("dri") refers to vision, sight, etc. This root is in the word दृषà¥à¤Ÿà¤¿ ("driZhTi" - or "drishti") - which means "aspect" - the way planets have a "line of sight" to one another.
In the context under discussion the word "dR" in dRk ("drik") means "visible" - in other words, observable positions.
The type of consonant at the end of the word is flexible according to rules of sandhi. So there is no need to obsess over drik or drig. In fact there is no need to obsess about spelling at all, since all these words are spelled in Devanagari alphabet, and engligh renditions are approximations. If we are going to obsess over spellings (which actually I would probably be pretty happy with) we should go to use diacritical marks, or since that is difficult with modern keyboards, the Harvard-Kyoto style.
