I always thought that SKY has no weight as when I look up it is all empty. But on google I found, the weight of the sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds, roughly 5.2 million billion tonnes.The sun is 3,33,000 times heavier than the earth.
Weight of the sky is roughly 5.2 million billion tonnes. This is approximately the same weight as 570,000,000,000,000 adult Indian elephants! The weight of one adult elephant is approx 4000 Kg.
