Wow; getting dizzy!

No wonder! Just found out we are going about 800,000 km/hr. as Sol drags us around the galaxy! :mrgreen: Not to mention other motion factors! Got me to wondering though how do you think that might play a part of the weather as we travel through different sides of the orbit! Do we go through cold areas or hot areas? does that create other problems? Ahh I don't have a clue! :roll:

I read someplace, a while ago, that the Solar system is about to enter into an interstellar dust cloud. How will that affect us?

Probably not much, since the gas cloud is sure to be extremely tenuous. Maybe, maybe, maybe it will make it a little harder for man-made telescopes to peer into the Universe.

Me thinks that Sol's hypersphere would keep the dust away from the Solar System :shock:! But I must confess that I'm speculating! :mrgreen:
