How Much Does a Star Weigh
A star’s weight is determined by its mass. The more massive a star is, the more gravity it has, and the more it weighs. Our Sun, for example, has a mass of about 2 x 10^30 kg.
That means that if you could somehow weigh it (which you can’t because it’s so huge and far away), it would weigh about 4 trillion trillion pounds!
A star’s weight is determined by its mass. The more massive a star is, the more gravity it has, and the heavier it is. Our Sun, for example, has a mass of about 333,000 times that of Earth.
That means it has 333,000 times as much gravity as our planet does. And since gravity is what gives things weight, that means the Sun weighs quite a bit more than Earth!
How Much Does a Star Weigh in Tons
A star’s weight is often determined by its mass. Mass is a measure of the amount of matter in an object. The more massive an object is, the more gravity it has.
Gravity is what keeps a star together. Without gravity, a star would simply be a cloud of gas and dust. The force of gravity pulls all of the material in a star toward its center.
This makes the star dense and hot at its core.
The pressure and temperature at the core of a star are so extreme that nuclear fusion can occur. Nuclear fusion is when atoms combine to form new atoms.
This releases energy, which helps to counteract the force of gravity and keep the star from collapsing in on itself.
The Sun, our nearest star, has a mass of about 333,000 times that of Earth. It weighs about 4×10^30 kilograms, or approximately 4 million billion billion tons!

How Heavy is a Star in Tons?
There is no definitive answer to this question as the weight of a star can vary greatly depending on its size and composition. However, we can approximate the weight of a star by using its mass and density.
The average density of a star is about 1 gram per cubic centimeter.
This means that a star with a mass of 1 solar mass (about 2 x 10^30 kg) would have aVolume = 4/3 π R^3 = 4/3 π (6.96 x 10^8 cm)^3 ≈ 1.41 x 10^27 cm^3weight = Mass / Volume ≈ 2 x 10^30 kg / 1.41 x 10^27 cm^3 ≈ 141 million tons!
Of course, this is just an approximation since there are many different types of stars with varying densities. For example, neutron stars are incredibly dense, with some weighing in at over 3 times the Sun’s mass but occupying only a few kilometers in diameter!
This gives them an average density of over 100 million grams per cubic centimeter – meaning that even though they’re much smaller than our Sun, they actually weigh more than 141 million tons!
How Much Does a Small Star Weigh?
A star’s weight is determined by its mass. The mass of a small star like our Sun is about 2 x 10^30 kg, or about 333,000 times the mass of Earth.
How Heavy is the Heaviest Star?
The heaviest star that has been discovered thus far is R136a1, which is about 265 times the mass of our Sun. This star is so massive that it is actually at the brink of collapse, and will eventually end its life in a supernova explosion.
What is the Average Mass of a Star?
There are many different types of stars in the universe, and each has its own mass. The average mass of a star is about 2 x 10^30 kg. This means that a star like our Sun has a mass of about 2 billion trillion tonnes!
Some stars are much more massive than this though. For example, the red supergiant Betelgeuse has a mass of about 20 times that of the Sun. There are also some very low-mass stars known as brown dwarfs which can have masses as low as just a few times that of Jupiter.
How Do We Weigh Stars?
Conclusion
A star’s weight is determined by its mass. The more massive a star is, the more gravity it has, and the more it weighs.
