It’s Friday the 13th! Eek! Everybody…RUN! Hide! Yeah, well, enough of the hysteria. We have plenty of that going on with the corona beer virus. Sugar, rice, pasta, Clorox & Lysol hand wipes, bleach, hand sanitizer and toilet paper doesn’t stand a chance. Now, we have to deal with the dreaded number 13. E-gads! The humanity!
March 13 has been a rather busy day in history. Curiously, Uranus and Pluto are involved.
Uranus is the seventh planet from the sun. The name of Uranus references the ancient Greek deity of the sky Uranus, the father of Cronus (Saturn) and grandfather of Zeus (Jupiter) […]. It has the third-largest planetary radius and fourth-largest planetary mass in [our] solar system and, […] is the only planet whose name is derived directly from a figure of Greek mythology. Uranus is similar in composition to Neptune and, both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. Uranus’ atmosphere is similar to Jupiter’s and Saturn’s in its primary composition of hydrogen and helium but, it contains more “ices” such as water, ammonia and methane […]. It has the coldest planetary atmosphere in the solar system […]. Like the other giant planets, Uranus has a ring system, a magnetosphere and numerous moons. The Uranian system has a unique configuration because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. Its north and south poles, therefore, lie where most other planets have their equators. Voyager 2 remains the only spacecraft to visit the planet.
Like the classical planets, Uranus is visible to the naked eye but, it was never recognised as a planet by ancient observers because of its dimness and slow orbit. [Two hundred, thirty-nine years ago, today], Sir William Herschel first observed Uranus on March 13, 1781 (from the garden of his house at 19 New King Street in Bath, Somerset, England, now the Herschel Museum of Astronomy), leading to its discovery as a planet, expanding the known boundaries of the solar system for the first time in history and making Uranus the first planet classified as such with the aid of a telescope.
Pluto is an icy dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It was the first Kuiper belt object to be discovered and is the largest known dwarf planet. Pluto was discovered by Clyde Tombaugh in 1930 as the ninth planet from the Sun. After 1992, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt. In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term “planet”, formally, in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.
It is the ninth-largest and tenth-most-massive known object directly orbiting the Sun. It is the largest known trans-Neptunian object by volume but, is less massive than Eris. Like other Kuiper belt objects, Pluto is primarily made of ice and rock and, is relatively small…about one-sixth the mass of the Moon and one-third its volume. It has a moderately eccentric and inclined orbit […]. This means that Pluto periodically comes closer to the Sun than Neptune but, a stable orbital resonance with Neptune prevents them from colliding.
[Observations] of Neptune in the late 19th century led astronomers to speculate that Uranus’s orbit was being disturbed by another planet besides Neptune. In 1906, Percival Lowell, a wealthy Bostonian who had founded [the] Lowell Observatory in Flagstaff, Arizona, in 1894, started an extensive project in search of a possible ninth planet, which he termed “Planet X“. Lowell and his observatory conducted his search until his death in 1916 but, to no avail. Unknown to Lowell, his surveys had captured two faint images of Pluto on March 19 and April 7, 1915 but, they were not recognized for what they were.
Percival’s widow, Constance Lowell, entered into a ten-year legal battle with the Lowell Observatory over her husband’s legacy and the search for Planet X did not resume until 1929. [23-year-old] Clyde Tombaugh, who had just arrived at the observatory, discovered a possible moving object on photographic plates on February 18, 1930. After the observatory obtained further confirmatory photographs, news of the discovery was telegraphed to the Harvard College Observatory ninety years ago, today, on March 13, 1930. Pluto has yet to complete a full orbit of the Sun since its discovery, as one Plutonian year is 247.68 years long.
The discovery made headlines around the globe. Lowell Observatory, which had the right to name the new object, received more than 1,000 suggestions from all over the world, ranging from Atlas to Zymal. Constance Lowell proposed Zeus, then Percival and finally Constance. These suggestions were disregarded. The name Pluto, after the god of the underworld, was proposed by Venetia Burney (1918–2009), an eleven-year-old schoolgirl in Oxford, England, who was interested in classical mythology.
After 59 years, the iconic Route 66 enters the realm of history on this day in 1985, when the American Association of State Highway and Transportation Officials decertifies the road and votes to remove all its highway signs. Measuring some 2,200 miles in its heyday, Route 66 stretched from Chicago, Illinois to Santa Monica, California, passing through eight states. According to a New York Times article about its decertification, most of Route 66 followed a path through the wilderness forged in 1857 by U.S. Navy Lieutenant Edward Beale at the head of a caravan of camels. Over the years, wagon trains and cattlemen eventually made way for trucks and passenger automobiles.
The idea of building a highway along this route surfaced in Oklahoma in the mid-1920s as a way to link the state to cities like Chicago and Los Angeles. Highway Commissioner Cyrus S. Avery touted it as a way of diverting traffic from Kansas City, Missouri and Denver. In 1926, the highway earned its official designation as Route 66. The diagonal course of Route 66 linked hundreds of mostly rural communities to the cities along its route, allowing farmers to more easily transport grain and other types of produce for distribution. The highway was also a lifeline for the long-distance trucking industry, which by 1930 was competing with the railroad for dominance in the shipping market.
Route 66 was the scene of a mass westward migration during the 1930s, when more than 200,000 people traveled from the poverty-stricken Dust Bowl to California. John Steinbeck immortalized the highway, which he called the “Mother Road”, in his classic 1939 novel The Grapes of Wrath. Beginning in the 1950s, the building of a massive system of interstate highways made older roads increasingly obsolete and, by 1970, modern four-lane highways had bypassed nearly all sections of Route 66. In October 1984, Interstate-40 bypassed the last original stretch of Route 66 at Williams, Arizona and, the following year, the road was decertified. According to the National Historic Route 66 Federation, drivers can still use 85 percent of the road and Route 66 has become a destination for tourists from all over the world.
Often called the Main Street of America, Route 66 became a pop culture mainstay over the years, inspiring its own song (written in 1947 [sic] by Bobby Troup, Route 66 was later recorded by artists as varied as Nat King Cole, Chuck Berry and The Rolling Stones) as well as a 1960s television series. More recently, the historic highway was featured prominently in the hit animated film Cars (2006).
