The primary is of magnitude 5.0 and the secondary is of magnitude 7.5. The 61 Cygni system is a Terran Federation controlled system. In the newly released History of the Universe in 21 Stars (and 3 Imposters), the star 61 Cygni has been revealed to be the smoking gun in our understanding of the cosmos 2 We have updated our Terms & … Although barely visual to the naked eye and appearing as a single star, 61 Cygni is actually a binary star, each which orbit around a common barycenter only every 659 years. It is now known that 61 Cygni A and B orbit each other at an "average" distance (semi-major axis) of 86.4 times the Earth-Sun distance, or about 86 astronomical units (AUs) -- which is It orbits at an average distance of 1.083 AU, but it varies drastically from 0.27 to 1.90 AU. 61 Cygni Bd is twice as massive as Earth at 2.02 Earth masses, straddling the border between super-Earth and mid-Earth. But the surface is not like Mars, it has numerous lakes and rivers of liquid ammonia. This system was visited for the first time on EDSM by iFred [SecB]. The wikipedia:en:61 Cygni binary star system comprises 61 Cygni A, also referred to as Swan, and a partner of unknown nickname but known formally as 61 Cygni B. Scott MacNeill / Frosty Drew Observatory. Breakdown: Anaconda - 1 The planet's density is just 6⁄7 of that of water and under 1⁄6 of that of Earth's, and half the density of Neptune. Because the stars are so far apart, they take many years to orbit each other – perhaps as many as 700 years. The planet's density is just 6⁄7 of that of water and under 1⁄6 of that of Earth's, and half the density of Neptune. 51 Cygni Facts. A mere 11 light years distant, the stars of 61 Cygni are among our closest neighbors. In 1838, Friedrich Bessel calculated the distance as 10.4 light-years, close to the modern figure. The star system 61 Cygni has a couple of distinctions. 61 Cygni is also called Gl 820, very rarely called Bessel's Star, and informally Proxima Cygni. This multiple star system is among the most interesting in the sky. 61 Cygni is a variable and multiple main-sequence star in the constellation of Cygnus. Sky's Edge (formerly Journey's End), the final destination for humanity's first human-crewed interstellar colonization effort, revolved around Swan. 61 Cyg Ab has 7⁄10 of the Earth's surface gravity, meaning that an average adult person would weigh about 107 pounds when standing on this planet. Things came to a head in the late 1830s, when three astronomers zeroed in on different stars, spending many nights at their telescope, often under harsh conditions. first human-crewed interstellar colonization effort, https://revelationspace.fandom.com/wiki/61_Cygni_system?oldid=6900.
