Mercury (planet) diagram on the right illustrates the effects of the eccentricity, showing Mercury's orbit overlaid with a circular orbit having the same semi-major axis. Mercury's higher velocity when it is near perihelion is clear from the greater distance it covers in each 5-day interval. In the diagram the varying distance of Mercury to the Sun is represented by the size of the planet, which is inversely proportional to Mercury's distance from the Sun. This varying distance to the Sun leads to Mercury's surface being flexed by tidal bulges raised by the Sun that are about 17 times stronger than the Moon's
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
