Từ tổng số 3.910 ngôi sao đã biết có ngoại hành tinh (tính đến ngày 1 tháng 2 năm 2023), có tổng cộng 853 hệ đa hành tinh đã biết,[1] hoặc các ngôi sao có ít nhất hai hành tinh đã được xác nhận ngoài Hệ Mặt Trời. Các ngôi sao có nhiều hành tinh được xác nhận nhất là Mặt Trời và Kepler-90 với 8 hành tinh đã được xác nhận, tiếp theo là TRAPPIST-1 với 7 hành tinh.
853 hệ đa hành tinh được liệt kê theo khoảng cách của ngôi sao với Trái Đất. Proxima Centauri, ngôi sao gần Hệ Mặt Trời nhất, có ba hành tinh (b, c và d). Hệ hành tinh gần nhất có bốn hành tinh đã được xác nhận trở lên là Tau Ceti. Hệ đa hành tinh được xác nhận xa nhất là OGLE-2012-BLG-0026L, cách 13.300 năm ánh sáng.[cần dẫn nguồn]
