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.

HD 192699 is a star in the Aquila constellation. 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 Aquila ( or, Eagle; sometimes named the Vulture) is one of the 48 Constellations listed by Ptolemy, also mentioned by Eudoxus (4th It is a yellow subgiant with apparent magnitude 6. 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 45, the distance is 220 ly. The cosmic distance ladder (also known as the Extragalactic Distance Scale) is the succession of methods by which astronomers determine the Distances to celestial A light-year or light year (symbol ly) is a unit of Length, equal to just under ten trillion Kilometres As defined by Based on its mass of 1. Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object 68 solar, it was an A-type star when it was a main-sequence. The solar mass is a standard way to express Mass in Astronomy, used to describe the masses of other Stars and galaxies. In Astronomy, stellar classification is a classification of Stars based initially on photospheric temperature and its associated Spectral characteristics The main sequence is the name for a continuous and distinctive band of stars that appear on a plot of stellar color versus brightness
In April 2007, a planet was announced orbiting the star, together with HD 175541 b and HD 210702 b. April 2007 is the fourth month of that year It began on a Sunday and 30 days later ended on a Monday. A planet, as defined by the International Astronomical Union (IAU is a celestial body Orbiting a Star or stellar remnant that is HD 175541 is an intermediate-mass Subgiant Star in the Constellation Serpens.

HD 192699 b is an exoplanet 2. Any Planet is an extremely faint light source compared to its parent Star. Doppler spectroscopy, also known as Radial velocity measurement is a spectroscopic method for finding Extrasolar planets It involves the observation An extrasolar planet, or exoplanet, is a Planet beyond the Solar System, orbiting around other Stars As of September 2008 312 5 times the mass of Jupiter. Despite of its orbital distance more than Earth, the orbital period is less than a year, that's because the parent star is more massive than the Sun. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 The orbital period is the time taken for a given object to make one complete Orbit about another object
It is one of the three planets that have indirect evidence for a planetary systems around the A-type stars.
