Binary stars are quite common in the universe. These are similar mass stars in which their common centers of masse lie outside either star, as predicted by the Universal Law of Gravitation. Often, binary stars appear as one star with the naked eye but through the scope two stars are apparent.

1. Give the name of a common binary star visible in your local sky. If part of a constellation, and altitude where possible.

2. Which type of possible binary star/s, hot or cold, would be easier for a telescope to resolve as being binary? Fully explain your answer, avoid unqualified statements, and offer rationale, based on the ideas in this chapter, when giving an answer.
