This article is about the sport. For the ball used in the sport, see Basketball (ball). For other uses, see Basketball (disambiguation). Basketball is a sport, generally played by two teams of five players on a rectangular court. The objective is to shoot a ball through a hoop 18 inches (46 cm) in diameter and mounted at a height of 10 feet (3.048 m) to backboards at each end of the court. A team can score a field goal by shooting the ball through the basket being defended by the opposition team during regular play. A field goal scores three points for the shooting team if the player shoots from behind the three-point line, and two points if shot from in front of the line.
