The orbit is not circular its shaped more like an oval. During the 3rd of January the northern part of the planet experiences summer and the southern experiences winter. During this time the earth is the closest to the sun than it will ever be along its orbit path. On the 3rd of July however the earth is the farthest away it will be during the year and the northern part of the planet now is experiencing winter while the southern experiences winter.
What ever you do in this life is the result of your next life, so if you are bad now then your next life isnt going to be good. However if you have been good in this life your next life will be better. God looks at the persons soul, not the colour if them , or the gender or race, but by the way they have acted which is all shown in the soul.
I hope this helps?
