Delta Draconis: 104.194.8.16:27016 If you need the diameter of the star, you just need to multiple the radius by 2. The Sun's radius is 695,800km, therefore the star's radius is an estimated 2,365,720.00.km. Eltanin Mass. The Sun's radius is 695,800km, therefore the star's radius is an estimated 33,488,854.00.km.

Gamma Draconis also has an M-class dwarf in orbit around it around a distance of 1,000 AU. Eltanin became famous when in 1728, James Bradley discovered the aberration of light, due to Earth's motion and the finite velocity of light, from observations of this star. Eltanin Radius has been calculated as being 48.13 times bigger than the Sun. - SIMBAD4 rel 1.7 - 2020.05.26CEST11:34:33 Available data : Basic data • Identifiers • Plot & images • Bibliography • Measurements • External archives • Notes • Annotations The Eltanin's solar mass is 1.72 times that of our star, the Sun. It is approximately 48 times the radius of the Sun, and the planetary system was thought to contain far more planets, though the innermost worlds were likely swallowed by the star as it expanded in the distant past. Thuban Radius. Sigma Draconis: 104.238.220.35:27016 Join Sigma Draconis!

Thuban Mass. Thuban Radius has been calculated as being 3.40 times bigger than the Sun. The Thuban's solar mass is 2.80 times that of our star, the Sun. Beta Draconis (β Draconis, abbreviated Beta Dra, β Dra) is a binary star and the third-brightest star in the northern circumpolar constellation of Draco.With an apparent visual magnitude of 2.79, it is bright enough to be easily seen with the naked eye.
