Question

Quizplus · Accepted Answer

All the planets in the solar system orbit the Sun in the same direction, which is counterclockwise when viewed from above the Sun's north pole. This direction is consistent with the direction of the rotation of the Sun and the initial rotation of the solar nebula from which the solar system formed. There is no planet that orbits the Sun in the opposite direction; thus, option D is not true.
