Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Wesleyan University
Wesleyan University ( ) is a Private university, private liberal arts college, liberal arts university in Middletown, Connecticut. Founded in 1831 as a Men's colleges in the United States, men's college under the auspices of the Methodist Episcopal Church and with the support of prominent residents of Middletown, the college was the first institution of higher education to be named after John Wesley, the founder of Methodism. It is now a secular institution. The college accepted female applicants from 1872 to 1909, but did not become fully co-educational until 1970. Before full co-education, Wesleyan alumni and other supporters of women's education established Connecticut College for women in 1912. Wesleyan, along with Amherst College, Amherst and Williams College, Williams colleges, is part of "The Little Three", also traditionally referred to as the Little Ivies. Its teams compete athletically as a member of the New England Small College Athletic Conference, NESCAC. Wesleyan ...

Yale University
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate col ...

Van Vleck Observatory
Van Vleck Observatory (VVO, IAU code 298) is an astronomical observatory owned and operated by Wesleyan University. It was built in 1914 and named after the former head of the Department of Mathematics and Astronomy at the university, Prof. John M. Van Vleck. It is located in Middletown, Connecticut (USA). This has a surviving Great refractor, a long telescope with lens popular in the late 1800s, as well as some other telescopes. Telescopes The University owns three telescopes. A and a are both used for weekly public observing nights, open to the Wesleyan community and the general public. The third telescope, the Perkins Telescope, is used primarily for research, including for senior and graduate student thesis projects, as well as for departmental research programs.

Trigonometric Parallax
Parallax is a displacement or difference in the apparent position of an object viewed along two different sightline, lines of sight and is measured by the angle or semi-angle of inclination between those two lines. Due to perspective (graphical), foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances. To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term ''parallax'' is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit. These distances form the lowest rung of what is called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial objects, serving as a basis for other distance measurements in astronomy forming the higher rungs of the lad ...

Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

2035 Stearns
2035 Stearns, provisional designation , is a bright Hungaria asteroid and sizable Mars-crosser inside the inner regions of the asteroid belt, approximately in diameter. It was discovered on 21 September 1973, by American astronomer James Gibson at the Leoncito Astronomical Complex in Argentina. The transitional E-type asteroid has a long rotation period of 93 hours. It was named after American astronomer Carl Leo Stearns. Orbit and classification ''Stearns'' is a dynamical Hungaria asteroid, a large group that forms the innermost dense concentration of asteroids in the Solar System. It is also a Mars-crossing asteroid, a member of the dynamically unstable group, located between the main belt and near-Earth populations, and crossing the orbit of Mars at 1.666  AU. The asteroid orbits the Sun in the inner main-belt at a distance of 1.64–2.13  AU once every 2 years and 7 months (945 days; semi-major axis of 1.88 AU). Its orbit has an eccentricity of 0.13 and an ...

Mars-crossing Asteroid
A Mars-crossing asteroid (MCA, also Mars-crosser, MC) is an asteroid whose orbit crosses that of Mars. Some Mars-crossers Minor planet designation, numbered below 100000 are listed here. They include the two numbered Mars trojans 5261 Eureka and . Many databases, for instance the JPL Small-Body Database (JPL SBDB), only list asteroids with a perihelion greater than 1.3 Astronomical Unit, AU as Mars-crossers. An asteroid with a perihelion less than this is classed as a near-Earth object even though it is crossing the orbit of Mars as well as crossing (or coming near to) that of Earth. Nevertheless, these objects are listed on this page. A grazer is an object with a perihelion below the aphelion of Mars (1.67 AU) but above the Martian perihelion (1.38 AU). The JPL SBDB lists 13,500 Mars-crossing asteroids. Only 18 MCAs are brighter than Absolute magnitude#Solar System bodies (H), absolute magnitude (H) 12.5, which typically makes these asteroids with H<12.5 more than 13 km in d ...

Stearns (crater)
Stearns is a lunar impact crater on the far side of the Moon. Unlike many lunar craters, this is a relatively fresh and well-defined impact feature with little appearance of erosion. The rim edge is sharp and roughly circular, with some unevenness. The inner walls are simple slopes down to piles of talus along the base. At the midpoint of the somewhat uneven interior floor is a central peak. This crater is located about midway between Appleton to the northwest and Nušl to the southeast. Just over one crater diameter to the south-southwest of Stearns is the smaller crater Steno. Stearns is a crater of Eratosthenian age.The geologic history of the Moon

Far Side Of The Moon
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the Near side of the Moon, near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar mare, lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury (planet), Mercury and Callisto (moon), Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Sovie ...

Wesleyan University Alumni
Wesleyan theology, otherwise known as Wesleyan– Arminian theology, or Methodist theology, is a theological tradition in Protestant Christianity based upon the ministry of the 18th-century evangelical reformer brothers John Wesley and Charles Wesley. More broadly it refers to the theological system inferred from the various sermons (e.g. the Forty-four Sermons), theological treatises, letters, journals, diaries, hymns, and other spiritual writings of the Wesleys and their contemporary coadjutors such as John William Fletcher. In 1736, the Wesley brothers travelled to the Georgia colony in America as Christian missionaries; they left rather disheartened at what they saw. Both of them subsequently had "religious experiences", especially John in 1738, being greatly influenced by the Moravian Christians. They began to organize a renewal movement within the Church of England to focus on personal faith and holiness. John Wesley took Protestant churches to task over the nature of s ...

1892 Births
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
