Situated on the B 4 a moon, Ben Uaine is one of two bright green mountains towering high above its surrounding plains, tall enough to be visible from orbit. Treating the explorer to a beautiful contrast of orange and green, the Martian-like soil of the moon's relatively flat surface is broken abruptly by these two green giants.

The taller of the two mountains, Ben Uaine, rises 8,400 metres above the surrounding valley. Climbing to its summit can be difficult, but pilots flying smaller ships can have an easier time of it: they can land on several of the "false summits" around the pinnacle of this emerald giant. As the surface gravity is only 0.14 g, taking an SRV up the mountainside is also an option... and maybe down from the summit as well.

At the right times, the view above can be quite remarkable: the Heart and Soul nebulae are close enough to be visible in the soft blue-green sky, and a cluster of luminous blue stars (from the 2MASS survey) can also be seen.
