Mercury (planet) at a steep angle. Mercury is 10° above the horizon when the planet appears directly above the Sun (i.e. its orbit appears vertical) and is at maximum elongation from the Sun (28°) and also when the Sun is 18° below the horizon, so the sky is just completely dark. This angle is the maximum altitude at which Mercury is visible in a completely dark sky. At middle latitudes, Mercury is more often and easily visible from the Southern Hemisphere than from the Northern. This is because Mercury's maximum western elongation occurs only during early autumn in the Southern Hemisphere, whereas
Ego the Living Planet the Fantastic Four as they were off planet at the time, fighting Ego. The superpowered quartet attempted to defeat Ego by removing the power cell from one of the attached, propulsion engines, which the Thing attempts to throw into Ego's "brain".
