Science question : distance from sun and the hemispheres

so what i want to know is this
if the sun is at its perihelion on the 3rd january which as you scientists will know is the closest to the earth, and also in january it is winter in the north hemisphere and summer in the southern hemisphere
and if the earth is at its aphelion or furthest point on the 5th july which is summer in north and winter in south etc....
does this mean that the summers are hotter in the southern hemisphere and the winters are colder due to this sun earth distance or doesn't it make a difference ps i know many factors make the temperature what it is but does this one make a difference
