In Astronomy, an epoch is a moment in time used as a reference for the Orbital elements of a Celestial body. In common usage a constellation is a group of celestial bodies that are connected together in some arrangement typically stars to form a visible figure or picture Each culture has its own Constellations usually based on Mythology. Lyra (ˈlaɪrə Lyre) is one of the 48 Constellations listed by Ptolemy, and is one of the 88 modern constellations recognized by the International Right ascension (abbrev RA; symbol α) is the Astronomical term for one of the two Coordinates of a point on the Celestial sphere In Astronomy, declination (abbrev dec or δ) is one of the two coordinates of the Equatorial coordinate system, the other being either The apparent magnitude ( m) of a celestial body is a measure of its Brightness as seen by an observer on Earth, normalized to the value 79 |

In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics In Astronomy, the color index is a simple numerical expression that determines the color of an object which in the case of a Star gives its Temperature In Astronomy, the color index is a simple numerical expression that determines the color of an object which in the case of a Star gives its Temperature For the astronomical object see Variable star. Variable Star is a 2006 novel written by Spider Robinson Astrometry is the branch of Astronomy that relates to precise measurements and explanations of the positions and movements of Stars and other celestial bodies Radial velocity is the Velocity of an object in the direction of the line of sight (i The proper motion of a Star is the measurement of its change in position in the sky over time after Improper motions are accounted for 2 mas/yr Dec. A minute of arc, arcminute, or MOA is a unit of angular measurement, equal to one sixtieth (1/60 of one degree.

A year (from Old English gēr) is the time between two recurrences of an event related to the Orbit of the Earth around the Sun Parallax is an apparent displacement or difference of orientation of an object viewed along two different lines of sight and is measured by the angle or semi-angle of inclination between 37 ± ? mas |

Planetary system
An extrasolar planet, designated TrES-1 was discovered by the Trans-Atlantic Exoplanet Survey by detecting the transit of the planet across its parent star using a small 4-inch diameter telescope. An extrasolar planet, or exoplanet, is a Planet beyond the Solar System, orbiting around other Stars As of September 2008 312 TrES-1, occasionally cataloged as GSC 02652-01324 b, is an Extrasolar planet approximately 512 Light-years away in the Constellation of The Trans-atlantic Exoplanet Survey or TrES, uses three 4-inch (10cm telescopes located at Lowell Observatory, Mount Palomar, and the Canary Islands The discovery was confirmed by the Keck Observatory using the radial velocity method, allowing its mass to be determined. The W M Keck Observatory is a two-telescope Astronomical observatory at the 4145 meter (13600 ft summit of Mauna Kea in Hawai'i. Radial velocity is the Velocity of an object in the direction of the line of sight (i
