100 billion stars in the “average” galaxy.

7*10²⁷atoms in a 70kg human. a star is a lot bigger.

I think the universe could have a ratio system involved from quarks all the way up to the universe itself.

well, seeing stars are mainly gas i would say they would also be fairly light sooooo rough estimate…tree fiddy,

why?

mass of sun

1.9885×10³⁰ kg

so how many 70kgs in that?

Just a thought, the universe has many different objects of many different sizes.

1.9885×10³⁰ /70

Something like 3×10²⁸

For the benefit of those without abacus or slide rule, that makes the number of atoms in an average sun about:

2×10⁵⁶

Tate says there are at least 2 trillion galaxies in the observable universe, so 2,000 billion x 100 billion stars/galaxy = 2 × 10^{23 stars, so stars have a bit of work to do to catch up with atoms.}

The old counting atoms to get to sleep trick.

None of the above answers compare by diameter.

Average atom = 1.06e-10 metres for H, 0.62e-10 metres for He.
Average star = 1.4e9 metres for the Sun, more than 1.4e11 metres for red giants
Average galaxy = 1.3e20 metres for the LMC, 2.1e21 metres for Andromeda

In terms of diameter, we have the approximate relation (for largish stars)
atom:human = human:star = star:galaxy
In each case about 1 to ten billion

I’m taking about size ratio like an ant to the empire state building

from quarks to all the larger particles then from particles to a planet then a star, then a solar system, then a galaxy, then a cluster of galaxies all the way up to the universe itself.

is the ratio a constant ?

yes it’s the solution to x^2 – x – 1 = 0 and it’s (1+sqrt(5))/2 and it’s known as the 197Au ratio

To give a bit more info…

quarks are dimensionless so we can’t determine a meaningful size ratio between them and “all the larger particles”

“all the larger particles” is a pretty big scope. Electrons are probably dimensionless as well, but have been demonstrated to be smaller than 10 ^-18 m. Neutrons and protons are much larger, some 1.7×10 ⁻¹⁵ m.

Planets also vary considerably in size. Under the current definition the smallest known is Mercury, some 5 × 10 ⁶ m across, but we can hypothesize smaller planets. The largest possible planet is something in the vicinity of 5 × 10 ⁸ m across.

Stars: The smallest possible star is around 3 × 10 ⁸ m in diameter. The largest known star is UY Scuti, about 2 × 10 ¹² m in diameter. Note that this range overlaps the range of diameters of planets.

Solar systems: arguably, our solar system is 10 ¹⁵ metres across, as the diameter of the Oort cloud. We don’t have any obs data on the Oort clouds of other stars, but it seems reasonable to suggest that the largest stars have “spheres of influence” at least an order of mag larger than our middling sized sun, and that the smallest solar systems might consist of a miniscule dwarf and a small amount of debris a few 10 ⁹ metres across.

The smallest galaxy known is Segue 2, some 2 x 10 ¹⁸ m across. The largest is IC 1101, which is 4 × 10 ²² m across.

The smallest galaxy clusters are approximately 10 ²³ m in diameter. The largest are approximately 5 × 10 ²³ across.

The size of the universe is a somewhat complex topic. The diameter of the observable universe is usually considered to be around 10 ²⁶ meters.

As you can see, the broad range of values in most of these categories you have suggested is so broad that it is hard to give meaningful precise ratios of diameter from one category to the next, but nonetheless we can still say the ratio between successive categories is not constant.

Sorry, braino/typo there. The diameter of the observable universe is usually considered to be around 10 ²⁷ meters.

These are order of mag estimates: Benford can’t save you now.

I answered that. In terms of size (diameter), these three ratios are close to constant, factor of 10^10.

atom:human, human:star, star:galaxy

In terms of size (volume), the ratios are also close to constant, factor of close to 10^30.
