How many justices serve on the Supreme Court?

The Supreme Court of the United States is composed of nine justices. This number has been established since 1869 and includes one Chief Justice and eight Associate Justices. The role of these justices is to interpret the Constitution and federal law, making decisions that can have a profound impact on American legal and social issues. The number of justices is set by Congress, and although there have been proposals to change it, the composition has remained at nine for well over a century. Each justice is appointed by the President and confirmed by the Senate, serving lifetime appointments unless they choose to retire or are removed through impeachment.
