A dozen orbits of EE-1 were sufficient for my survey. Tidally locked, no atmosphere, not even remotely livable. The planet looked a lot like pictures I’d seen of Mercury. Hellish hot, pools of what might be liquid lead, deep chasms in the surface from which came the deep red glow of hot magma. Gravimetric readings indicated a surprisingly high density, probably due to a large core. Good indications of mineral wealth, so this planet would be interesting to any colonists.
