630 Euphemia
630 Euphemia is a mid-sized Eunomian asteroid. Photometric observations at the Palmer Divide Observatory during 2005 showed a best fit rotation period of 79.18 ± 0.02 hours with a brightness variation of 0.2 ± 0.02 in magnitude. However, some uncertainty remains concerning the reliability of this result. References External links Lightcurve plot of 630 Euphemia Palmer Divide Observatory, '' B. D.

August Kopff
August Kopff (February 5, 1882 – April 25, 1960) was a German astronomer and discoverer of several comets and asteroids. Kopff studied and worked in Heidelberg, getting his PhD there in 1906 and he then joined the Humboldt University of Berlin where he became the Director of the Institute for Astronomical Calculation. He discovered some comets, including periodic comet 22P/Kopff and the non-periodic C/1906 E1. He discovered a number of asteroids, including notably the Trojan asteroids 617 Patroclus and 624 Hektor. The lunar crater ''Kopff (crater), Kopff'' is named after him, as is the asteroid 1631 Kopff. Minor planet 805 Hormuthia is named after his wife, Hormuth.

Eunomia Asteroids
In Greek mythology, Eunomia () was a minor but important goddess of law and legislation and her name can be translated as "good order", "governance according to good laws", as well as the spring-time goddess of green pastures (''eû'' means "well, good" in Greek, and νόμος, ''nómos'', means "law", while pasturelands are called ''nomia''). She is by most accounts the daughter of Themis and Zeus. Her opposite number was Dysnomia (Lawlessness). Horae Eunomia was the goddess of law and legislation and one of the Second Generation of the Horae along with her sisters Dikē and Eirene. The Horae were law and order goddesses who maintained the stability of society, and were worshipped primarily in the cities of Athens, Argos and Olympia. From Pindar: ''Eunomia'' and that unsullied fountain '' Dikē'', her sister, sure support of cities; and '' Eirene'' of the same kin, who are the stewards of wealth for humanity—three glorious daughters of wise-counselled Themis.Pindar, Thir ...

Brian D
Brian (sometimes spelled Bryan in English) is a male given name of Irish and Breton origin, as well as a surname of Occitan origin. It is common in the English-speaking world. It is possible that the name is derived from an Old Celtic word meaning "high" or "noble". For example, the element ''bre'' means "hill"; which could be transferred to mean "eminence" or "exalted one". The name is quite popular in Ireland, on account of Brian Boru, a 10th-century High King of Ireland. The name was also quite popular in East Anglia during the Middle Ages. This is because the name was introduced to England by Bretons following the Norman Conquest. Bretons also settled in Ireland along with the Normans in the 12th century, and 'their' name was mingled with the 'Irish' version. Also, in the north-west of England, the 'Irish' name was introduced by Scandinavian settlers from Ireland. Within the Gaelic-speaking areas of Scotland, the name was at first only used by professional families of Iri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnitude (astronomy)
In astronomy, magnitude is a measure of the brightness of an astronomical object, object, usually in a defined passband. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. Magnitude values do not have a unit. The scale is Logarithmic scale, logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Thus each step of one magnitude is \sqrt[5] \approx 2.512 times brighter than the magnitude 1 higher. The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values. Astronomers use two different definitions of magnitude: apparent magnitude and absolute magnitude. The ''apparent'' magnitude () is the brightness of an object and depends on an object's intrinsic luminosity, its Cosmic distance ladder, distance, and the Extinction (astronomy), extinction reducing its brightness. The ''absolute'' magnitude () describes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotation Period
In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the '' sidereal rotation period'' (or ''sidereal day''), i.e., the time that the object takes to complete a full rotation around its axis relative to the background stars ( inertial space). The other type of commonly used "rotation period" is the object's '' synodic rotation period'' (or ''solar day''), which may differ, by a fraction of a rotation or more than one rotation, to accommodate the portion of the object's orbital period around a star or another body during one day. Measuring rotation For solid objects, such as rocky planets and asteroids, the rotation period is a single value. For gaseous or fluid bodies, such as stars and giant planets, the period of rotation varies from the object's equator to its pole due to a phenomenon called differential rotation. Typically, the stated rotation period for a giant pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photometry (astronomy)
In astronomy, photometry, from Greek '' photo-'' ("light") and '' -metry'' ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. This light is measured through a telescope using a photometer, often made using electronic devices such as a CCD photometer or a photoelectric photometer that converts light into an electric current by the photoelectric effect. When calibrated against standard stars (or other light sources) of known intensity and colour, photometers can measure the brightness or apparent magnitude of celestial objects. The methods used to perform photometry depend on the wavelength region under study. At its most basic, photometry is conducted by gathering light and passing it through specialized photometric optical bandpass filters, and then capturing and recording the light energy with a photosensitive instrument. Standard sets of passbands (called a photometric system) are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Euphemia
Euphemia (; 'well-spoken f), known as Euphemia the All-praised in the Eastern Orthodox Church, was a virgin martyr, who died for her faith at Chalcedon in 303 AD. According to tradition, Euphemia was martyred for refusing to offer sacrifices to Ares. She was arrested and after suffering various tortures, died in the arena at Chalcedon from a wound sustained from a bear. Her tomb became a site of pilgrimages. She is commemorated on September 16. Historical background Euphemia's name and year of death are recorded in the 5th century '' Martyrologium Hieronymianum'', the earliest extant list of Christian martyrs. The year, 303, was the first year of the Great Persecution under Roman emperor Diocletian. The '' Fasti vindobonenses'', a collection of liturgical documents from the 4th to 6th centuries, says she died on the 16th of October. Other than this, there is no verifiable historical information about Euphemia. Egeria, who made a pilgrimage to the Holy Land about 381-384 and ...
