61 Cygni is a binary star system in the constellation Cygnus.
Both stars have a spectral type of K, which means there temperature is around
4,500 K. This is cool for a star.
See related question for the hottest star.
Something is missing from your question. Cygni is not a star. The constellation name is Cygnus. The star will have a name like Alpha Cygni or 25 Cygni.
61 Cygni is a binary star system consisting of two orange dwarfs. Because of this configuration it is unlikely that any planets would have been able to form because of the gravitational tug of the two stars. To date, no planets have been confirmed in this system.
NML Cygni or V1489 Cygni is a red hypergiant star and the largest star currently known, at about 1,650 times the Sun's radius
Chi Cygni is a variable star, meaning its brightness varies cyclically. Chi Cygni's temperature is typically given as 3000 K.
NML Cygni, is a Red Hypergiant star, currently the largest know, and one of the most luminous in the Galaxy.
The Earth is about 11.4 light years away from the binary system cygni. Cygni is not the name of a star. It refers to the constellation cygnus (the swan), and is used in the names of stars and other objects within that constellation. For example, the system 61 cygni and the star gamma cygni. The constellation doesn't have a single distance from the earth because the objects of which it is made are all at different distances. For example, the brightest star in the constellation, referred to as alpha cygni, is at a distance of 1630 light years, while gamma cygni, the third brightest star in the constellation, is at a distance of about 1800 light years. 61 cygni on the other hand is only about 11 light years from earth.
