Delta Draconis - Properties

Properties

Delta Draconis is a giant star with a stellar classification of G9 III. This indicates that, at an estimated age of 800 million years, this star has exhausted the supply of hydrogen at its core and entered a later stage in its evolution. The angular diameter of the star is estimated as 3.37 ± 0.06 mas. At a parallax of 32.54 mas, this corresponds to a physical radius equal to 11 times the solar radius. It is radiating 59 times the luminosity of the Sun from its outer atmosphere at an effective temperature of 4,820 K. At this temperature, it is giving off the yellow-hued glow of a G-type star. With a mass 2.32 times that of the Sun, this star will end its life as a white dwarf.

    A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.
    Ralph Waldo Emerson (1803–1882)

    The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.
    John Locke (1632–1704)
