The sun is just mostly gas. Do you mean how much it would weigh, if only solid mass was left?
Yes if the sun was put into rock form how much would it weigh and would it be able to be picked up?
I don’t think you understand the size difference between the Sun and anything human relatable. Its circumference is more than a hundred times the distance around the Earth (which itself is a difficult thing to comprehend), and that’s just distance, not volume. A typical sunspot is about the size of our planet or larger.
Okay, very confusing question…
So, assuming you want to know how heavy only the “solid at room temperature” elements of the sun are, let’s try this.
The sun is 1.989 × 10^30 kilograms.
According to this: https://www.thoughtco.com/element-composition-of-sun-607581 we can see the % of total mass for each element.
- Element % of total atoms % of total mass
- Hydrogen 91.2 71.0
- Helium 8.7 27.1
- Oxygen 0.078 0.97
- Carbon 0.043 0.40
- Nitrogen 0.0088 0.096
- Silicon 0.0045 0.099
- Magnesium 0.0038 0.076
- Neon 0.0035 0.058
- Iron 0.030 0.014
- Sulfur 0.015 0.040
Doing the math and removing the “gas at room temperature” elements… the total mass would be:
1.7901 * 10^28 kilograms
Note: Pretty sure I’ve messed something up here in the calculations but the mass is so ridiculously heavy that I don’t think it really matters.
Not many rocks don’t have some oxygen atoms in them, so I chose to include all the astronomical “metals” in my estimate. Interesting to see how little difference it makes.
Well it’s not wet, but if you stopped the reactions, the sheer force of gravity of the upper layers on the inner layers would start them again. Not that that has any effect on its mass. (I mean it does, because the nuclear reactions convert mass to energy, but that’s a very long process.)
Asking weight doesn’t really make sense, because weight is a product of gravity. The sun has a mass of 1.9891x10^30 kg, and at 1g that’s 4.384x1030 lb, at least according to the Google result summary I copy-pasted from.
So if I was on a less gravity planet it would be easy to pick up?
Most of the sun is hydrogen and helium, which is not the kind of stuff that rocks are made of. Wikipedia says that 0.0122 of it is heavier elements, which might more often be found in rocks, so if we imagine it’d be possible to make one big rock out of all that somehow, its mass would be 1.2% that of the sun = 2.4 * 10^28 kg, or 4000 times more than Earth.
