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. Sextans (ˈsɛkstənz sextant is a minor equatorial Constellation which was introduced in the 17th century by Johannes Hevelius. 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 31 |

HD 92788 is a yellow dwarf star in the constellation Sextans. History The first direct measurements of an object at interstellar distances were undertaken by German Astronomer Friedrich Wilhelm Bessel in 1838 In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue In Astronomy, a G V star is a Main-sequence Star of spectral type G and luminosity class V 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 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 Sextans (ˈsɛkstənz sextant is a minor equatorial Constellation which was introduced in the 17th century by Johannes Hevelius. It is more massive and slightly smaller than the Sun with high metallicity. The Sun (Sol is the Star at the center of the Solar System. In Astronomy and Physical cosmology, the metallicity of an object is the proportion of its matter made up of Chemical elements other than Hydrogen

| Semi-major axis | 0. Any Planet is an extremely faint light source compared to its parent Star. Any Planet is an extremely faint light source compared to its parent Star. A provisional designation in astronomy is the naming convention applied to Astronomical objects immediately following their discovery 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 Geometry, the semi-major axis (also semimajor axis) is used to describe the dimensions of ellipses and hyperbolae 97 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 332±0. 011 |
| Orbital period | 325. The orbital period is the time taken for a given object to make one complete Orbit about another object 94±0. 22 d |
| Average orbital speed | 32. 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 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 5 km/s |
| Angular distance | 29. In Mathematics (in particular Geometry and Trigonometry) and all Natural sciences (including astronomy geophysics etc the angular distance 6 mas |
| Longitude of periastron | 275. A minute of arc, arcminute, or MOA is a unit of angular measurement, equal to one sixtieth (1/60 of one degree. In Astrodynamics, the longitude of the periapsis (symbolized \varpi of an orbiting body is the Longitude (measured from the point of the vernal equinox In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from 7±2. 8° |
| Time of periastron | 2450758. In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from 0±2. 4 JD |
| Semi-amplitude | 106. The Julian date (JD is the interval of time in days and fractions of a day since 4713 B Amplitude is the magnitude of change in the oscillating variable with each Oscillation, within an oscillating system 2±1. 8 m/s |

| Mass | >3. Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object 68 MJ |
HD 92788 b is a low-mass superjovian exoplanet orbiting at 0. An extrasolar planet, or exoplanet, is a Planet beyond the Solar System, orbiting around other Stars As of September 2008 312 97 astronomical units from HD 92788. 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
