Visual binary Jump to: navigation, search A visual binary is a gravitationally bound system[1] that can be resolved into two stars with the aid of a telescope.These stars are estimated, via Kepler's 3rd law, to have periods ranging from a number of years to thousands of years.. VISUAL BINARY STARS 17.1 Introduction Many stars in the sky are seen through a telescope to be two stars apparently close together. The bright two stars of the constellation Gemini, Castor and Pollux, make a famous example of a visual binary; these two stars, and their apparent motions over time, have been observed for hundreds of years. As mass is such a key property of stars and to a large extent knowing a star's mass determines its life cycle and fate, being able to accurately determine stellar masses is vital in refining our models of stars.
