The sun is the superpower that provides life to our planet, but do you know how much it weighs? How heavy does the sun feel on your shoulders when you’re outside? You may have heard different answers. For example, some people say that a single banana weighs more than the sun. But others disagree and tell you that if we converted all of the matter in the universe into pounds, then our solar system would weigh as much as a feather! Do not be discouraged by this discrepancy- I will show you how to find out for yourself!
You can weigh the sun by using Newton’s law of gravitation to determine its mass (remember that gravity pulls things together). The only problem is you have never seen a scale quite this big! Scientists use a unit called the solar masses. One solar mass equals the total amount of matter in our Sun, which is equivalent to one-third of all stars and planets combined. So if you want to figure out how much our sun weighs, just multiply it by three trillion kilos-or 33 billion pounds for us English speakers!
The average weight per gallon across Earth’s oceans has been estimated at 55 lbs/gal or 166 kg per cubic meter. These values are averages because water density varies due to variations in salinity and temperature. As a result, the average weight of water in our oceans is not known exactly and may vary from one part to another.
The sun’s density varies tremendously between different layers (its core has nearly twice the density as its surface). The total mass of all these variations combined equals that of 333 million Earths! However, solar particles are so hot and diffuse at temperatures over two million degrees Kelvin that they can’t be measured by current methods without vaporizing them first. For this reason, we cannot calculate how much the sun weighs with any degree of accuracy; however, there have been some guesses pegged around 330 billion trillion pounds or 17 sextillion tons for those who prefer Imperial units.”
Does the Sun weigh more than Earth?
Yes, it’s about 333 million times heavier than earth. However, because it doesn’t have any atmosphere to hold on to its gravity, you can escape from it anywhere and go into space without much difficulty. In fact, if everyone on Earth jumped at once, we would all be able to fly away with ease!
Many people are wondering how heavy the sun is. From our work on calculating gravity, we know that it’s about 333 million times heavier than Earth. However, because of its low density and extreme heat in the core (around two million degrees Kelvin), many calculations can’t be made without vaporizing it first.” How do they weigh the Sun? In addition to this difficulty, “we don’t have a really good way to measure mass outside of earth,” says Grisha Perelman of NASA Goddard Space Flight Center.
“The only thing you can do is an estimate by looking at other stars which are similar – but not identical – to ours”. This leaves scientists with an imprecise measurement for their solar system’s most important star.
For a more precise answer, you will have to ask an expert in astrophysics. That is not me! But we do know that it’s 333 million times heavier than Earth, and two million degrees Kelvin on the inside – without being able to measure its mass accurately. Solar astronomers use measurements of brightness or radius as alternative metrics for estimating solar properties.”
A sun’s weight can be estimated by measuring its volume with a simple experiment:
fill up a glass jar with water from your kitchen tap (don’t worry about how much) and tip it out into some cups. The height difference between the top of the column of water in each cup tells you how many cubic meters there are at this depth beneath the surface, which means if you can read off the volume of water in cubic meters and multiply it by the density of water (1000 kg/m^) you’ll have an estimate for the weight.
A solar mass or MSun, which implies that there are about 300 million billion stars in our galaxy. The total number of stars inside both galaxies may be as high as one trillion! We’ve done some calculations to find out how much you can expect to spend on fuel if you want to get your car from Los Angeles all up into space.”
