((The hammer is what gives him his god powers yes. Mjilnor was created by odin to only be capable of being lifted by one man, and that man would become his son. Only one other time has it been lifted by someone other then the destined Thor, and that was by Pecos Bill (not sure about the name) and due to there now being two Thors they fought and eventually Odin made a second. In this idea there is one and like the original it bestows the powers of Thor, so all of the God energy originates from it so in a way yes. But he threw it for a good reason.))
Thor closed his eyes and focused on the hammer, he then performed Tranferred Senses, which would temperarily places his senses on the hammer.
Forcing the hammer into max speed, he looked around through it as he shot all around the sun.
To those around him he would look to be asleep.
