Claimed Moons Of Earth
Claims of the existence of other moons of Earth—that is, of one or more natural satellites with relatively stable orbits of Earth, other than the Moon—have existed for some time. Several candidates have been proposed, but none have been confirmed. Since the 19th century, scientists have made genuine searches for more moons, but the possibility has also been the subject of a number of dubious non-scientific speculations as well as a number of likely hoaxes. Although the Moon is Earth's only natural satellite, there are a number of near-Earth objects (NEOs) with orbits that are in resonance with Earth. These have been called "second" moons of Earth or "minimoons". , an asteroid discovered on 27 April 2016, is possibly the most stable quasi-satellite of Earth. As it orbits the Sun, 469219 Kamoʻoalewa appears to circle around Earth as well. It is too distant to be a true satellite of Earth, but is the best and most stable example of a quasi-satellite, a type of near-Earth objec ...

Frédéric Petit (astronomer)
Frédéric Petit (Muret, 1810 – Toulouse, 1865) was a French astronomer. He was the first director of the Toulouse Observatory, located in Toulouse, France, serving from 1838 to 1865. In 1846 he announced that he had discovered a second moon of Earth. The theory was later dismissed by his peers, although the concept of a second smaller satellite of the Earth was used by Jules Verne in his novel ''From the Earth to the Moon ''From the Earth to the Moon: A Direct Route in 97 Hours, 20 Minutes'' (french: De la Terre à la Lune, trajet direct en 97 heures 20 minutes) is an 1865 novel by Jules Verne.

New-York Tribune
The ''New-York Tribune'' was an American newspaper founded in 1841 by editor Horace Greeley. It bore the moniker ''New-York Daily Tribune'' from 1842 to 1866 before returning to its original name. From the 1840s through the 1860s it was the dominant newspaper first of the American Whig Party, then of the Republican Party. The paper achieved a circulation of approximately 200,000 in the 1850s, making it the largest daily paper in New York City at the time. The ''Tribune''s editorials were widely read, shared, and copied in other city newspapers, helping to shape national opinion. It was one of the first papers in the north to send reporters, correspondents, and illustrators to cover the campaigns of the American Civil War. It continued as an independent daily newspaper until 1924, when it merged with the ''New York Herald''. The resulting ''New York Herald Tribune'' remained in publication until 1966. Among those who served on the paper's editorial board were Bayard Taylor, Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ezekiel Stone Wiggins
Ezekiel Stone Wiggins (December 4, 1839 – August 14, 1910) was a Canadian weather and earthquake predictor known as the "Ottawa Prophet". He was the author of several scientific, educational and religious works. Early life and education Ezekiel Wiggins was born in Grand Lake, Queens County, New Brunswick, in 1839 to Daniel Slocum Wiggins and Elizabeth Titus Stone, both of United Empire Loyalist descent. The Wiggins family claims descent from Capt Thomas Wiggins of Shrewsbury, England who became the first Governor of New Hampshire in 1630. Ezekiel was a pupil at the Oakwood Grammar School (1858). He attended secondary school in Ontario, and stayed to become a teacher in Mariposa Township, Ontario. On August 2, 1862, he married his sixteen-year-old cousin Susan Anna Wiggins, the daughter of Vincent White Wiggins and Charlotte E. Wiggins. The couple did not have any children. Their religion was Episcopal. Susan became an author and poet. He was a student at the Philadelphia Univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synodic Period
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. For celestial objects in general, the sidereal period (sidereal year) is referred to by the orbital period, determined by a 360° revolution of one body around its primary, e.g. Earth around the Sun, relative to the fixed stars projected in the sky. Orbital periods can be defined in several ways. The tropical period is more particularly about the position of the parent star. It is the basis for the solar year, and respectively the calendar year. The synodic period incorporates not only the orbital relation to the parent star, but also to other celestial objects, making it not a mere different approach to the orbit of an object around its parent, but a period of orbital relations with oth ...

Georg Waltemath
Dr. Georg Wilhelm Waltemath (August 24, 1840 – September 27, 1915) was an astronomer from Hamburg, best known for his 1898 claim of a second moon of Earth as well as a system of tiny moons. It is widely held to be false. Second Moon He is believed to have begun his search for one of the largest satellites which he claimed to exist based on the hypothesis that something was gravitationally affecting the Moon's orbit.Public Opinion: A Comprehensive Summary of the Press Throughout the World on All Important Current Topics, published by Public Opinion Co., 1898: "The Alleged Discovery of a Second Moon", p 369Book/ref> He gave detailed information into it which is given below: *Distance from earth: 1030000 km (640000 miles) *Diameter: 700 km (430 miles) *Orbital period: 119 days *Synodic period: 177 days He claimed that it was not normally visible with the naked eye but predicted it would be visible between 2 and 4 February 1898.

Around The Moon
''Around the Moon'' (french: Autour de la Lune, 1869), also translated as ''Circling the Moon'' and ''All Around the Moon'', is the sequel to Jules Verne's 1865 novel, ''From the Earth to the Moon''. It is a science fiction tale which continues the trip to the Moon that was only begun in the first novel. Later English editions sometimes combined the two under the title ''From the Earth to the Moon and Around It''. ''From the Earth to the Moon'' and ''Around the Moon'' served as the basis for the 1902 film '' A Trip to the Moon''. Plot Having been fired out of the giant Columbiad space gun, the Baltimore Gun Club's bullet-shaped projectile, along with its three passengers, Barbicane, Nicholl and Michel Ardan, begins the five-day trip to the Moon. A few minutes into the journey, a small, bright asteroid passes within a few hundred yards of them, but does not collide with the projectile. The asteroid had been captured by the Earth's gravity and had become a second moon. The thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Verne
Jules Gabriel Verne (;''Longman Pronunciation Dictionary''. ; 8 February 1828 – 24 March 1905) was a French novelist, poet, and playwright. His collaboration with the publisher Pierre-Jules Hetzel led to the creation of the ''Voyages extraordinaires'', a series of bestselling adventure novels including ''Journey to the Center of the Earth'' (1864), ''Twenty Thousand Leagues Under the Seas'' (1870), and '' Around the World in Eighty Days'' (1872). His novels, always well documented, are generally set in the second half of the 19th century, taking into account the technological advances of the time. In addition to his novels, he wrote numerous plays, short stories, autobiographical accounts, poetry, songs and scientific, artistic and literary studies. His work has been adapted for film and television since the beginning of cinema, as well as for comic books, theater, opera, music and video games. Verne is considered to be an important author in France and most of Europe, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altitude
Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the "down" direction are commonly referred to as depth. In aviation In aviation, the term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used. Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or ...

Apsis
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g., f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
