I come twice a year to balance the Earth's extremes. I rule the longest day for some, and the longest night for their counterparts. What am I?

Not for dessert That i will assert Where camels linger And scorpions flash their stingers

In the openness of this space I was called ever expansive and wide

You get pizza from a Pizzeria. You get tacos from a Taqueria. Where do Hamburgers live?

I travel far but weigh so little, I carry a view and a brief small riddle. I speak in a message from places away, Then rest in a drawer when memories stay. I am stamped and sent with a simple intent, A little hello from where you went. What am I, slim and bright in my role, A paper message that travels the whole?
