Earth circles the Sun once a year while its axis keeps pointing the same way in space. The picture at the bottom left is the Earth from space view at the same moment: Earth seen from high above the north side of this orbit, with the Sun to the left.
Press Play to watch a year. The axis never turns: it leans toward the Sun in June and away from it in December because Earth has moved to the other side of the Sun.
Earth goes around the Sun each year with its axis pointing one way; over about 25,800 years that direction circles. Because the orbit is slightly oval, northern summer moves from the far point (today) to the near point, where summers get more sunlight and winters less.
