鉄を撃った結果、太陽にはほとんど何も起こりません。地球の地殻内のすべての鉄の総重量は、約1.385×10^21 kgです。太陽に送るために必要なすべての鉄とエネルギーを除去するために地球に与える影響を無視すると、到着した後、太陽にほとんど影響を与えません。


現在、太陽は約0.1％の鉄です。つまり、太陽の中には現在1.988×10^27 kgの鉄があり、地球のすべての鉄の約140万倍の鉄があります。その結果、太陽の融合プロセスに有意義に影響を与えるためには、地球のすべての地殻よりもはるかに多くの鉄を使用する必要があります。
Almost nothing would happen to the sun as a result of shooting iron at it.  The total weight of all the iron in the Earth's crust is approximately 1.385×10^21 kg.  Disregarding the effect it would have on the earth to remove all the iron and the energy required to send it into the sun, it would have little to no effect on the sun once it arrived.


The sun is currently about 0.1% Iron, which means there are currently aproximately 1.988×10^27 kg of iron in the sun or about 1.4 million times as much iron as all the iron in the earth's crust.  As a result, in order to meaningfully affect the fusion processes in the sun, you'd have to use vastly more iron than is in all of the earth's crust.
