how many judges make up the supreme court

The Supreme Court of the United States is made up of nine judges, known as justices. This includes one Chief Justice and eight Associate Justices. This composition has been in place since 1869 and is established by the Judiciary Act of 1869. The number of justices is set by Congress, not the Constitution, which allows flexibility in the Court's size, but it has remained at nine for over 150 years
