Don’t say you don’t have enough time. You have exactly the same number of hours per day that were given to Helen Keller, Pasteur, Michelangelo, Mother Teresa, Leonardo Da Vinci, Thomas Jefferson, and Albert Einstein. ~H. Jackson Brown
1846 – Astronomers Urbain Jean Joseph Le Verrier, John Couch Adams and Johann Gottfried Galle collaborate on the discovery of Neptune.
Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Among the gaseous planets in the Solar System, Neptune is the most dense. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense. Neptune orbits the Sun at an average distance of 30.1 astronomical units. Named after the Roman god of the sea, its astronomical symbol is ♆, a stylised version of the god Neptune’s trident.
Neptune was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier, and its largest moon, Triton, was discovered shortly thereafter, though none of the planet’s remaining 13 moons were located telescopically until the 20th century. Neptune has been visited by one spacecraft, Voyager 2, which flew by the planet on 25 August 1989.

1889 – Nintendo Koppai (Later Nintendo Company, Limited) is founded by Fusajiro Yamauchi to produce and market the playing card game Hanafuda.
Nintendo Co., Ltd. is a Japanese multinational consumer electronics company headquartered in Kyoto, Japan. Nintendo is the world’s largest video game company by revenue. Founded on September 23, 1889 by Fusajiro Yamauchi, it originally produced handmade hanafuda playing cards. By 1963, the company had tried several small niche businesses, such as cab services and love hotels.
Abandoning previous ventures in favor of toys in the 1960s, Nintendo then developed into a video game company in the 1970s, ultimately becoming one of the most influential in the industry and Japan’s third most valuable listed company with a market value of over US$85 billion. Nintendo of America is also the majority owner of the Seattle Mariners Major League Baseball team.
The name Nintendo can be roughly translated from Japanese to English as “leave luck to heaven.” As of March 31, 2014, Nintendo reports historically cumulative sales of over 670.43 million hardware units and 4.23 billion software units.
