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
A Beautiful Planet star about half the size and mass of the Sun which lies in the direction of the constellation Cygnus, about 500 light-years away. The number "186" in the planet's name refers to the order in which its planetary system was discovered while scientists processed all of the data produced by the Kepler Space Telescope, and the planet itself is designated "f" because the first planet to be discovered in the system is designated as planet "b," the second discovered is "c," etc., and it was the fifth planet to be discovered. Even though the idea of interstellar travel to another
