This planet is likely the Space Agency analogue of Mars. It has a low gravitational pull. Due to this, it is difficult to land. A failed attempt will result in the lander bouncing off of the surface, or exploding on impact.
From RED (+13) you can reach YEL (875), GRN (730), and LUN (990).
The radius of the planet has been calculated to be about 2.46 NaviComp units.
Using LUN is a great check point especially if you send a few refuel tanks into orbit.
Unlike the real-world planet Mars, which RED is based off, RED has no atmosphere.
