Eh? Where does it show that they're not in the sun. He wasn't in the sun for a long time, for sure. But I'd say fighting in the sun with no soak time leaves him at least as powerful as sitting in it for a while and fighting somewhere else.
And that version of superman was certainly strong (moving warworld, the size of a small moon). But thanos has busted a planet accidentally in a fistfight -- presumably one much larger than earth, given that earth is a very small planet. (earth = 100x moon in mass)
Superman is outmatched in the one area where he typically outclasses people -- strength. And, of course, thanos has many other powers....
