Are there more grains of sand on earth or more stars in the sky?
According to some estimates, there are 4.8 x 1022 grains of sand on Earth, and an estimated 5 x 1022 stars in the universe. The Bible says that there are a lot of stars in the sky and lots of grains of sand on a beach, and most of the other things referring to space in the Bible have been found to be true some thousands of years later. So they're about the same, give or take a factor of ~.2 :)
What is the number of particles in the universe?
It is estimated that there are 10^12 galaxies in the universe, each with about 10^12 stars. Each star has an average of 10^57 hydrogen atoms; using these estimates, the number of particles in the universe would be about 10^82.
What percentage of carbon dioxide is on venus?
In order to answer that question it is necessary to know how much carbon dioxide there is on Venus and how much is in the whole universe. Whereas the former can be estimated, there is little hope of estimating the latter to any degree of accuracy. However, based on the estimated number of galaxy clusters, and galaxies within those clusters, and stars within those galaxies with planetary systems, it is likely that the percentage of universal carbon dioxide that is on Venus is as close to 0% as makes no difference.
Is the number of stars finite or infinite?
The number of stars is finite.
What compromises 99 percent of matter in the universe?
It is currently estimated that about 4% of the matter of the Universe is "normal" matter - matter that can be accounted for. This includes stars, dust, gas, and even black holes. About 23% of the matter is "dark matter", which makes itself manifest by its gravitational attraction - but that is about all we know about it. The remaining 73% is an even more mysterious "dark energy" - which somehow makes the Universe expand faster and faster.It is currently estimated that about 4% of the matter of the Universe is "normal" matter - matter that can be accounted for.

About how many stars are estimated to occur in pairs or multiples?
binary stars, more than 50 percent of the stars in the universe may occur in pairs or multiples.
How many stars appear in pairs or multiples?
its hard to know that we still trying to find out
How many stars stars are in our galaxy?
Estimated at 200-400 billion stars.
What are stars that are found in pairs?
Two stars that are gravitationally bound to each other are sometimes called "binary stars".
How are distances estimated by studying stars and clusters and the galaxy?
the space from the planet the stars or clusters
What are stars found in pairs called?
Stars found in pairs are called binary stars. Binary stars orbit around a common center of mass due to gravitational attraction between them.
How many stars are there in the galaxy?
A typical galaxy may have anywhere between a few million (106) stars, and over a trillion (1012) stars. Our own Milky Way is estimated to have between 200 and 400 billion (2x1011-4x1011) stars.
Are yellow stars hotter than blue stars?
No Blue stars are estimated to have an effective temperature of ≥ 30,000 K Blue-white stars are estimated to have an effective temperature of 10,000-30,000 K By contrast, yellow stars only have an effective temperature of 5,200-6,000 K. Even yellow-white stars are only 6,000-7,500 K
How many stars our there in our galaxy?
It has been estimated that there are between 200 -> 400 billion stars in the Milky Way Galaxy
How many stars are there?
There are estimated to be around 100 billion stars in our Milky Way galaxy, and there are an estimated 100-200 billion galaxies in the observable universe. This means there could be around 10^24 stars in the observable universe.
What percentage of stars are binary stars?
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
Why does nuclear fusion not occur on earth?
Because the conditions of temperature and pressure that occur in stars do not occur on earth
