Well, about his limits, is not that we have seen Gravattack doing something "hard" with his powers yet. By hard I mean to lift or move anything massive or big enough to actually make him put a noticeable  effort and make the show viewers (AKA us the people) to think "man, that thing Gravattack is fighting sure has to weight a lot!". It haven't occurred, because of two main reasons: first, Gravattack has only been used 3 times (I know, 4, but I never usually count the one in "Hot Stretch" because he was on screen less than 30 seconds) and everything he has been used to is lifting a giant battle robot, redirect some projectiles and levitate some bad guys.

Only with this information, is fairly impossible to put a limit to Gravattack's skills. The only thing left is to speculate.

Gravattack, as far as we know, is a tiny planet. If his body mass was the mass an object of his size (almost the same as Armodrillo or Fourarms, I guess), his powers would be absolutely impossible, violating Newton's well-known laws. Besides, Armodrillo and Fourarms (and Humungosaur, Diamondhead, even Way Big!) are as big or even bigger than him and don't have any gravitation effect. The point is, that in order for Gravattack to control gravity the way he does, he has to be A LOT heavier than he looks, therefore, his density has to be huge.

And with this comes the doubt: we have no possible way to guess Gravattack's weight nor density, and is not a thing that will appear explained in a kids show. So, let's speculate again; if we accept that Gravattack's weighs as much as a tiny planet (Mars, for example), the limits to his powers would be in a planetary scale: he could easily use his powers over ANYTHING below planetary/asteroidal/satellital standards of weight/size (this is, I repeat, just accepting the posibility that he weights the same as a real-life planet). But, if we put him in the order of "heaviness" of more dense objects, such as neutron stars or white dwarf, the limits to his powers would be even way beyond comprehension: he could move stars, change the trajectory and orbits of planetary objects at will, crash any mass into a tiny space, touch black holes, etc. Anyhow, I don't personally believe his powers reach that much (maybe some more powerful member of his species maybe, but even that way, I don't believe it possible).

So, conclusion for Shayan1000000: Gravattack might (and only might) has gravity powers in a tiny planetary scale, putting his limits on the movement or attraction of small/medium heavenly bodies. Hope that puts a temporary answer to your question (remember that all this is pure speculation) :)
