Orbital periods can be less than an hour (for AM CVn stars), or a few days (components of Beta Lyrae), but also hundreds of thousands of years (Proxima Centauri around Alpha Centauri AB).

Famous quotes containing the word period:
“In a period of a people’s life that bears the designation “transitional,” the task of a thinking individual, of a sincere citizen of his country, is to go forward, despite the dirt and difficulty of the path, to go forward without losing from view even for a moment those fundamental ideals on which the entire existence of the society to which he belongs is built.”
—Ivan Sergeevich Turgenev (1818–1883)
