Are there more atoms in one grain of sand than there are stars in the known universe?
No. Sand grains vary quite a but in size, but for our purposes let us consider a spherical grain of sand composed of quartz that is 1 millimeter in diameter. Such a grain would have a mass of about 0.0014 grams and given the formula of SiO2, with a molar mass of 60 grams per mole, would contain about 4.2*10^19 (42 quintillion) atoms. It is hard to estimate the number of stars in our universe and there do not appear to be any reliable sources. There are about 100 billion galaxies in the known universe and own galaxy contains an estimated 200 billion stars, but it is significantly larger than the average galaxy. If we figure the average galaxy contains about 20 billion stars then we get an estimate of 2.0*10^21 (2 sextillion) stars in the known universe universe, about 50 times the number of atoms in our sand grain.

What characteristics are used to describe stars?
Stars can be described by their temperature, size (diameter), brightness (luminosity), color, composition, and age. These characteristics help scientists classify and study stars in the universe.
Which is the star in the center of the universe?
There is no singular star in the center of the universe. Our universe is vast and does not have a center. Stars are spread throughout the universe in galaxies, and our sun is just one of the billions of stars in the Milky Way galaxy.
How many atoms are there in the universe?
Oh, isn't that just fascinating to think about? Well, my friend, the exact number of atoms in the universe is incredibly hard to quantify because the universe is so vast and ever-expanding. But just know that each atom is a tiny part of something grand and beautiful, just like every brushstroke in a painting. So, let's focus on appreciating the wonder and beauty of the atoms we do know about - they are the building blocks of everything we see around us, making the universe an infinitely stunning place to explore.
Is the sun a larger star than all other stars?
No, the Sun is an average-sized star compared to other stars in the universe. There are much larger stars, known as supergiants, which can be hundreds of times larger than the Sun.
What is the most abundant state of matter in the solar system?
plasma i think...Dark_Energy_&_Dark_Matter">Answer: Dark Energy & Dark MatterIn the newest research, it is said that for calculations to make sense regarding the mass of the universe, an unknown (at that time) substance must exist aside from ordinary matter (atoms). To provide some numbers (percentage of matter in known Universe):Atoms: 4.6%Dark matter: 23%Dark energy: 72%For more info see the link below.
What is the population of stars in the universe?
For every grain of sand on every beach on Earth there is a star in the univese
How does the size of the sun compare to that of other stars in the universe?
The size of the sun is considered average compared to other stars in the universe. There are much larger stars, known as supergiants, and much smaller stars, known as dwarfs. The sun falls in the middle range in terms of size among the billions of stars in the universe.

how many stars are in th sky?
approximately 200 billion trillion stars in the universe.
How does the size of the sun compare to that of other stars?
The size of the sun is considered average compared to other stars. There are much larger stars, known as supergiants, and smaller stars, known as dwarfs, in the universe.

What produces all known element in the universe other hydrogen?
fusion reactions in stars
How many atoms in the univearse?
There is an infinite number of atoms in the universe. This is because the universe never ends, it is always expanding. So, since you can't measure how large the universe is, as it is ever-expanding, you cannot determine how many atoms are in the universe.alternate view. Though the universe may be infinite, that is not the same thing as boundless. And of course most of the universe is space without matter in it.Astrophysicist Arthur Eddington estimated the number of hydrogen atoms in the Universe to be about 10^73, and even with knowledge of 'Dark matter' that would only add a few digits to the exponent. Today's best guess along those lines is around 10^80. (Also known as the Dirac large number hypothesis.)This is a long way from infinite, and even a long way from a Googol or a Googolplex.
What produces all the known elements in universe other than hydrogen?
fusion reactions in stars
What do you know about universe?
The universe is everything that exists. There is no sound in the universe because the sound waves cannot travel through anything. The universe is made up of nothing, there are no atoms that let the sound travel. But the planets and the stars are made up of atoms. In the universe, there are galaxies. In the galaxies are the stars, the black holes and the solar systems. The solar systems are made of planets and a star, but who knows, maybe there are 2 stars in a solar system so far from our. Everyone knows that the sun is a star. We know that the sun is the biggest thing in our solar system. But it's not the second biggest thing in the universe. Compared with other stars that are bigger, you cannot even imagine how small our sun is. Sometimes you cannot see it on images.
How are atoms of different elements distributed throughout the universe?
Atoms of different elements are distributed throughout the universe through processes such as nuclear fusion in stars, supernova explosions, and cosmic ray interactions. These processes create and disperse various elements into space, where they eventually coalesce into new stars, planets, and other celestial bodies. The distribution of elements in the universe is a result of the evolution and interactions of matter over billions of years.
Where are stars in the universe?
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
