The more massive planets in the solar system tend to be less dense than the lower mass planets. All the planets in the solar system have at least one moon. All the planets in the solar system rotate in the same direction as they orbit the Sun, Within the frost line, planetesimals were composed entirely of rock; outside the frost line, planetesimals were composed entirely of ice. Pluto is the largest solar system object beyond the orbit of Neptune. All planets orbit the Sun in the same direction (counterclockwise when viewed from above Earth's North Pole)Explanation / Answer
