The loosely bound binary star system GI 777 (alternatively HR 7670 or BD+29 3872 ABab) is located more than 52 lightyears from the Solar system, in the constellation Cygnus.[1][2] The brighter star GI 777 A, a yellow dwarf star, is llocated 51.8 lightyears from Sol, while GI 777 B is 3,000 astronomical units (0.047 ly) farther away.
The system is 6.7 billion years old, about fifty percent older than Sol, our sun.[2] The larger star contains at least two exoplanets, both gas giants.[2]
