472 Roma
472 Roma is an asteroid. It was discovered by Luigi Carnera on July 11, 1901. Its provisional name was 1901 GP. This asteroid was named by Antonio Abetti for the city of Rome in Italy, the native country of its discoverer. At 21:57 UT, on Thursday, July 8, 2010, this 50 km wide asteroid occulted the star Delta Ophiuchi in an event lasting about five seconds. The occultation path crossed central Europe along a band that ran through Stockholm, Copenhagen, Bremen, Nantes and Bilbao. This is a member of the dynamic Maria family of asteroids that were probably formed as the result of a collisional breakup of a parent body.

Luigi Carnera
Luigi Carnera (born in Trieste April 14, 1875, died in Florence, July 30, 1962) was an Italian astronomer and mathematician. He discovered 16 minor planets in the early 20th century. The main-belt asteroid 39653 Carnera was named in his honour. In his early career he worked as Max Wolf's assistant at Heidelberg, Germany he discovered a number of asteroids. He worked in Germany, Italy and Argentina before returning to Italy for good in 1908. He was director of Trieste Observatory starting in 1919; Trieste had just been annexed to Italy following World War I. He then became director of Capodimonte Observatory in Naples starting in 1932 and until his retirement in 1950.

Julian Day
The Julian day is a continuous count of days from the beginning of the Julian period; it is used primarily by astronomers, and in software for easily calculating elapsed days between two events (e.g., food production date and sell by date). The Julian period is a chronological interval of 7980 years, derived from three multi-year cycles: the Indiction, Solar, and Lunar cycles. The last year that was simultaneously the beginning of all three cycles was , so that is year 1 of the current Julian period, making AD year of that Period. The next Julian Period begins in the year AD 3268. Historians used the period to identify Julian calendar years within which an event occurred when no such year was given in the historical record, or when the year given by previous historians was incorrect. The Julian day number (JDN) has the same epoch as the Julian period, but counts the number of days since the epoch rather than the number of years since then. Specifically, ...

Julian Year (astronomy)
In astronomy, a Julian year (symbol: a or aj) is a unit of measurement of time defined as exactly 365.25 days of SI seconds each.P. Kenneth Seidelmann, ed.''The explanatory supplement to the Astronomical Almanac'' (Mill Valley, Cal.: University Science Books, 1992), pp. 8, 696, 698–9, 704, 716, 730. Reprinted from the "IAU Style Manual" by G.A. Wilkinson, Comm. 5, in IAU Transactions XXB (1987).Harold Rabinowitz and Suzanne Vogel''The manual of scientific style''(Burlington, MA: Academic Press, 2009) 369. The length of the Julian year is the average length of the year in the Julian calendar that was used in Western societies until the adoption of the Gregorian Calendar, and from which the unit is named. Nevertheless, because astronomical Julian years are measuring duration rather than designating dates, this Julian year does not correspond to years in the Julian calendar or any other calendar. Nor does it correspond to the many other ways of defining a year. Usage The Ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane (mathematics), plane angle in which one Turn (geometry), full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI Brochure, SI brochure as an Non-SI units mentioned in the SI, accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Iranian calendar, Persian calendar and the Babylonian calendar, used 360 days for a year. ...

Asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. Of the roughly one million known asteroids, the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU ...

Antonio Abetti
Antonio Abetti (19 June 1846 – 20 February 1928) was an Italians, Italian astronomer. Born in San Pietro di Gorizia (Šempeter-Vrtojba), he earned a degree in mathematics and engineering at the University of Padua. He was married to Giovanna Colbachini in 1879 and they had two sons. He died in Arcetri. Work Abetti mainly worked in positional astronomy and made many observations of minor planets, comets, and star occultations. He computed the orbit of 170 Maria, a Main belt asteroid. In 1874 he was part of an Italian expedition to Muddapur, in India, led by Pietro Tacchini to observe a transit of Venus with a spectroscope. Later he became director of the Osservatorio Astrofisico di Arcetri and a professor at the University of Florence. He refurbished the observatory at Arcetri by installing a new telescope.

Delta Ophiuchi
Delta Ophiuchi (δ Ophiuchi, abbreviated Delta Oph, δ Oph), formally named Yed Prior , is a star in the constellation of Ophiuchus. It forms a naked-eye optical double with Epsilon Ophiuchi (named ''Yed Posterior''). The apparent visual magnitude is 2.75, making this a third-magnitude star and the fourth-brightest in the constellation. Parallax measurements from the Hipparcos spacecraft yield a distance estimate of approximately from the Sun, while Epsilon Ophiuchi is approximately away. Nomenclature ''δ Ophiuchi'' ( Latinised to ''Delta Ophiuchi'') is the star's Bayer designation. It bore the traditional name ''Yed Prior''. ''Yed'' derives from the Arabic يد ''yad'' "hand". ''Delta'' and ''Epsilon Ophiuchi'' comprise the left hand of Ophiuchus (the Serpent Bearer) that holds the head of the serpent (Serpens Caput). ''Delta'' is ''Yed Prior'' as it leads ''Epsilon'' across the sky. In 2016, the International Astronomical Union organized a Working Group on Star Nam ...
