| Epoch December 31, 2006 (JD 2454100. Events 708 - Copper coins are minted in Japan for the first time (Traditional Japanese date: August 10, 708) Year 1862 was a Common year starting on Wednesday (link will display the full calendar of the Gregorian calendar (or a Common year starting on Monday A provisional designation in astronomy is the naming convention applied to Astronomical objects immediately following their discovery The asteroid belt is the region of the Solar System located roughly between the orbits of the Planets Mars and Jupiter. In Physics, an orbit is the gravitationally curved path of one object around a point or another body for example the gravitational orbit of a planet around a star In Astronomy, an epoch is a moment in time used as a reference for the Orbital elements of a Celestial body. Events 406 – Vandals, Alans and Suebians cross the Rhine, beginning an invasion of Gallia. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar.

| Aphelion | 515. In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from 376 Gm (3. 445 AU) |
| Perihelion | 315. In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from 937 Gm (2. 112 AU) |
| Semi-major axis | 415. In Geometry, the semi-major axis (also semimajor axis) is used to describe the dimensions of ellipses and hyperbolae 657 Gm (2. For other meanings see Giga (disambiguation Giga- (symbol G is a prefix in the SI system of units denoting 109 The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International 778 AU) |
| Eccentricity | 0. The astronomical unit ( AU or au or au or sometimes ua) is a unit of Length based on the distance from the Earth to the In Astrodynamics, under standard assumptions, any Orbit must be of Conic section shape 240 |
| Orbital period | 1691. The orbital period is the time taken for a given object to make one complete Orbit about another object 658 d (4. A day (symbol d is a unit of Time equivalent to 24 Hours and the duration of a single Rotation of planet Earth with respect to the 63 a) |
| Average orbital speed | 17. In Astronomy, a Julian year (symbol a) is a unit of measurement of Time defined The orbital speed of a body generally a Planet, a Natural satellite, an artificial satellite, or a Multiple star, is the speed at which it 61 km/s |
| Mean anomaly | 36. The second ( SI symbol s) sometimes abbreviated sec, is the name of a unit of Time, and is the International System of Units In the study of orbital dynamics the mean anomaly of an orbiting body is the Angle the body would have traveled about the center of the orbit's Auxiliary circle 838° |
| Inclination | 4. Inclination in general is the Angle between a Reference plane and another plane or axis of direction 075° |
| Longitude of ascending node | 197. This article describes the unit of angle For other meanings see Degree. The longitude of the ascending node (☊ or Ω is one of the Orbital elements used to specify the Orbit of an object in space 313° |
| Argument of perihelion | 174. The argument of periapsis (or argument of perifocus) ( ω) is the Orbital element describing the Angle of an Orbiting body's periapsis 519° |

| Dimensions | 118. 7 km |
| Mass | 1. Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object 8×1018 kg |
| Mean density | ? g/cm³ |
| Equatorial surface gravity | 0. The density of a material is defined as its Mass per unit Volume: \rho = \frac{m}{V} Different materials usually have different A cubic centimetre or cubic centimeter (symbol cm3 —the abbreviation cc, though widely used is deprecated is a commonly used unit of Volume The surface gravity, g, of an astronomical or other object is the Gravitational acceleration experienced at its surface 0332 m/s² |
| Escape velocity | 0. In Physics, escape velocity is the speed where the Kinetic energy of an object is equal to the magnitude of its Gravitational potential energy 0628 km/s |
| Rotation period | ? d |
| Albedo | 0. The rotation period of an astronomical object is the time it takes to complete one revolution around its Axis of rotation relative to the background stars The albedo of an object is the extent to which it diffusely reflects light from the sun 043 [1] |
| Temperature | ~167 K |
| Spectral type | C[2] |
| Absolute magnitude | 8. Temperature is a physical property of a system that underlies the common notions of hot and cold something that is hotter generally has the greater temperature The kelvin (symbol K) is a unit increment of Temperature and is one of the seven SI base units The Kelvin scale is a thermodynamic C-type asteroids are Carbonaceous Asteroids They are the most common variety forming around 75% of known Asteroids {Fact|date=July 2008}} and an even higher In Astronomy, absolute magnitude (also known as absolute visual magnitude) is the Apparent magnitude an object would have if it were at a standard 66 |
74 Galatea (gal'-ə-tee'-ə, IPA: /ˈɡæləˈtiːə/) is a large Main belt asteroid. The asteroid belt is the region of the Solar System located roughly between the orbits of the Planets Mars and Jupiter. Asteroids, sometimes called Minor planets or planetoids', are bodies—primarily of the inner Solar System —that are smaller than planets but Its surface is very dark in color. Galatea was found by the prolific comet discoverer Ernst Tempel on August 29, 1862 in Marseilles, France. A comet is a small Solar System body that orbits the Sun and when close enough to the Sun exhibits a visible coma (atmosphere or a tail — Events 708 - Copper coins are minted in Japan for the first time (Traditional Japanese date: August 10, 708) Year 1862 was a Common year starting on Wednesday (link will display the full calendar of the Gregorian calendar (or a Common year starting on Monday Marseille, ( English alt Marseilles mɑrˈseɪ — French: maʁsɛj locally — Provençal Occitan: Marselha maʀˈsijɔ This article is about the country For a topic outline on this subject see List of basic France topics. It was his third asteroid discovery. It is named after one of the two Galateas in Greek mythology. For the Sicilian Nereid in love with Acis, see Acis and Galatea (mythology For the wife of Lamprus, who prayed to Greek mythology is the body of stories belonging to the ancient Greeks concerning their gods and Heroes the nature of the world and the origins and significance A stellar occultation by Galatea was observed on September 8, 1987. A star is a massive luminous ball of plasma. The nearest star to Earth is the Sun, which is the source of most of the Energy on Earth In Shia Islam The Occultation is a term used to designate the hidden state of the Imam of the Time. Events 70 - Roman forces under Titus sack Jerusalem. 1264 - The Statute of Kalisz Year 1987 ( MCMLXXXVII) was a Common year starting on Thursday (link displays 1987 Gregorian calendar) The name Galatea has also been given to one of Neptune's satellites. See also Neptune ( English|AmE] ] is the eighth and farthest Planet from the Sun in the Solar System. A natural satellite or moon is a Celestial body that Orbits a Planet or smaller body which is called the primary.
