It's impossible for his super saiyan to trigger here since it only triggers with anger so i will automatically assume no super saiyan.
Goku at this level at 10x Genkidama is already above millions...
Piccolo at 300 busted a moon in DBZ ( i won't use roshi's feat in db since it is a different series after all ) which is pretty much believable because vegeta claimed that he could bust the earth with one attack at 18,000, so it is a common sense that goku at this level can bust much more.
Goku is ATLEAST large planet level at this level ( Should've used start of namek saga when he was weaker than 2nd form frieza )
For speed , piccolo's special beam cannon at 300 powerlevel reached the moon in seconds, yet raditz at 1200 was able to dodge it, it is common sense for goku at this level to be atleast a hundred times faster.
Anyway if that acid rain isn't some kind of hax then goku wins, he can probably evade that rain.
their body is actually extremely similar to ours.
The funny thing is, saiyan's can breathe in space and swim to depths.
