A lot of people think Saitama sneezed away Jupiters' atmosphere. But the thing is that Jupiter doesn't have a solid surface, but it has a solid core. So he sneezed away not only the top, gaseous layers, but also the liquid ones, which is most of Jupiter's mass. And since he can do that, he can punch away a star too(same as Garou and Boros' Collapsing star roaring cannon).
However both for Saitama and DBZ characters(late versions, earlier versions might struggle greatly) lifting 15 earth masses is quite easy, as DBZ characters can be considered confirmed planet busters(ok, in DBZ planets are small, but characters slowly get stronger). So something like ultra instinct Goku can punch away a planet for sure, which requires around 10^32 joules instead of 8*10^26 joules. For Saitama, who is star buster, which requires around 10^44 – 10^45 joules those black holes are almost unnoticeable weight. Makes sense that he's bored with fighting normal opponents.
