Basketball is a team sport played by two teams of 5 players each. The objective is to score more points than the opposing team by shooting a ball through a hoop mounted 10 feet high. Players advance the ball up the court by dribbling, passing, or shooting. The game is played on a rectangular court and has evolved over time from Dr. James Naismith's original 13 rules developed in 1891. Key skills include dribbling, passing, shooting, and rebounding within the rules of the game.
