Stellar Components
The primary star, HD 188753 A, is similar to the Sun with a mass only 6% larger and a stellar classification of G8V. Orbiting this primary at a distance of 12.3 AU is a pair of smaller stars that orbit each other with a period of 156.0 ± 0.1 days, a semi-major axis of 0.67 AU, and eccentricity of 0.1 ± 0.03. The pair have a estimated masses of 0.96 and 0.67 solar masses. They orbit the primary with a period of about 25.7 years and an orbital eccentricity of about 0.50. The periastron distance of this orbit is 6.2 AU.

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
