The stars orbit the center of mass once every 659 years at an average separation of 84 AU. The primary (A) is a cool K5 main sequence star that is suspected to be variable (from 5.19 to 5.27 magnitude). It also has high proper motion, also calling this the "Flying Star.". It is due to combined even forces exerted by three planets beyond it and gravity of the nearby star. It has a density 17% higher than water, meaning that this planet is an ice giant like Uranus and Neptune. 61 CYGNI is a binary star system which consists of two orange-red dwarfs with highly elliptical orbits that separates them, on average, by 84 AUs. It is an ocean planet with oceans over 200 miles deep, surrounded by atmosphere of adequate thickness made of hydrogen, oxygen, and water vapor. The 61 Cygni system is a Terran Federation controlled system. This density value tell that this planet has a thick hydrogen-helium atmosphere surrounding the oceans of liquid water/ammonia mixture. 61 Cygni Ab orbits at about 0.5 AU (5⁄9 the Earth–Sun distance), and takes half an Earth year to revolve around the star. The planet Tellar Prime and its moon Scott are both located in this system. These planets have semimajor axes ranging from 0.18 AU to 3.15 AU and have orbital periods from over a month to nearly seven years. More typical Milky Way stars shift by mere ten-thousandths of an arcsecond—just hundredths of a pixel in a modern telescope camera. 61 Cygni was the first star system (other than the Sun) to have its distance to Earth successfully calculated by Friedrich Wilhelm Bessel (1784-1846) using trigonometric parallax and the diameter of the Earth's orbit around the Sun in 1838. This system was located approximately eleven light years from the Sol system, part of the constellation Cygnus . It was later determined that the object masses 8 Jupiters taking 4.8 years to orbit at 2.4 AU. Smaller and dimmer than Sol… 61 Cyg Ac has mass 22 Earth masses and diameter 64.3 megameters, producing the density slightly less than water. Deneb, Alpha Cygni (α Cyg), is a class A supergiant located at an approximate distance of 1,550 light years from Earth. A year later, these claims were found to be spurious as sensitivities at the time can only go down to about 60 Jupiter masses. As it is typical of planets in the 61 Cyg system, this one orbits eccentrically, although it has one of the lower eccentricities of all planets. The 61 Cygni system is exceptionally close. 51 Cygni Facts. All three planets orbiting A are gaseous, two are midplanets and one is a low-mass sub-Jupiter.
