The metoer isnt made from chakra, its from space. Even if it was made from chakra, how would pretha path absorb it. Its solid, he cannot. Even if he absorbs the first one (which i believe he cannot), where would he absorb the second one lmao.Look I honestly would not want preta to be able to absorb the meteor, because one that would be OP and two that would look hilarious. But the fact remains that preta can absorb chakra that materializes even into physical substance such as fire, wind, or even oil, so until proven otherwise, if the meteor is made from chakra it can be absorbed.
If you havent noticed it has absrobed 2 forms of rasengan, oil+fire and 8 tailed demon cloak. All these would also get absorbed by samahada.
Ask yourself whether samahada can absorb a metoer because they more or less have the same qualities
