Stellar and System Characteristics
Delta Muscae has a listed spectral type of K2III. The K2 portion of this designation specifies that Delta Muscae A is a class K2 star, meaning the light it emits is orange in color. The main star burns at a temperature cooler than our own sun (Sol), which is a G2 star. K2 stars are on the smaller end of the Harvard spectral classification list, solely being larger than Class-M dwarves. The second part of the classification, III, specifies that Delta Muscae is a giant star which has yet to reach the main sequence of star life like our sun.
These spectral designations are for the main star in the Delta Muscae system. The system itself has been identified as a spectroscopic binary star system; this means that Delta Muscae was identified as a binary system by analyzing the Doppler Effect from the emitted light of the star. There is no available data concerning Delta Muscae A's companion.

Famous quotes containing the word system:
“Human beings are compelled to live within a lie, but they can be compelled to do so only because they are in fact capable of living in this way. Therefore not only does the system alienate humanity, but at the same time alienated humanity supports this system as its own involuntary masterplan, as a degenerate image of its own degeneration, as a record of people’s own failure as individuals.”
—Václav Havel (b. 1936)
