When the earth is at perihelion, is it the summer solstice or the winter solstice?

Learn geography well.

Because the earth is the farthest place from the earth when it is at perihelion (because the path of the earth's revolution around the sun is elliptical, this should be known), so think about it, when the sun is far away from you, it should be very cold. When will it be cold in summer and winter? Of course, it is winter, so it is about the winter solstice, but it is not necessarily the winter solstice.
