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 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 A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue A star catalogue, or star catalog, is an Astronomical catalogue that lists Stars In Astronomy, many stars are referred to simply by catalogue 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 For other meanings see Perseus (disambiguation Perseus (ˈpɝsiːəs or /-sjuːs/ is a northern Constellation, named after the Greek It is the 7th magnitude star located 170 light years away. 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 A light-year or light year (symbol ly) is a unit of Length, equal to just under ten trillion Kilometres As defined by The visual luminosity of the star is 1. Luminosity has different meanings in several different fields of science 71 times greater than our Sun. The Sun (Sol is the Star at the center of the Solar System. HD 23596 dwarfs the Sun is terms of physical properties; including mass, radius, age, metallicity, and temperature. The spectrum of the star is F8.
The star is unusual as it have one known detected planet.

HD 23596 b is an exoplanet orbiting the star HD 23596. Any Planet is an extremely faint light source compared to its parent Star. Radial velocity is the Velocity of an object in the direction of the line of sight (i An extrasolar planet, or exoplanet, is a Planet beyond the Solar System, orbiting around other Stars As of September 2008 312 The planet is very massive, at least 7. 8 times that of Jupiter, classifying as mid-superjovian. Based on its mass, the planet would probably be a gas giant with no solid surface but with gaseous ocean. A gas giant (sometimes also known as a Jovian planet after the planet Jupiter, or giant planet) is a large Planet that is not primarily The planet orbits at the average distance of 2. 83 AU, taking 1565 days to complete its orbit with average velocity of 19. 7 km/s. The eccentricity of the planet’s orbit is higher than all the planets in our solar system, bringing as close as 2. The Solar System consists of the Sun and those celestial objects bound to it by Gravity. 00 AU to as far as 3. 66 AU from the parent star. Combining with very massive planet (7. 8 MJ) and wide separation (2. 83 AU) will yield high semi-amplitude of 124 m/s. Amplitude is the magnitude of change in the oscillating variable with each Oscillation, within an oscillating system
The planet was discovered by Perrier et al. in 2002 using his radial velocity technique to look for changes in toward (blue-shifting) and away (red-shifting) stellar motion in the sky [radial velocity]. Any Planet is an extremely faint light source compared to its parent Star. Radial velocity is the Velocity of an object in the direction of the line of sight (i
