Good question! However, as it happens, aphelion and perihelion are not related to the summer and winter solstices. The times of aphelion/perihelion are slowly shifting. In 1246 a.d., for example, perihelion and the December solstice were on the same day. Now, they are a few weeks apart. In 6430 a.d., perihelion is expected to align with the March equinox.
