Are you kidding?
It's like asking how many water molecules are in the world's oceans.
The number is close to infinitity. They are everywhere and can always continue to be produced.

we cant accurately detect neutrinos. until recently we cant detect 2/3 of neutrinos (muon and tau neutrinos). we dont know all of the areas they produce them.
the estimated number of hydrogen atoms in the universe is something like 10^81. thats a 1 followed by 81 zeros. i would assuming that the number of neutrinos would be much greater since they come from a much larger number of sources (stars, supernovae, antimatter (particles or clouds of it).

While I'm typing this answer hundreds of thousands of neutrinos are zipping through me so you can understand that to count the number in the universe is totally impossible.

There has been type of radiation belived to have been observed as what science calls Neutrino. However ;no one really has explained what kind of substance it is. Therefore, its existence has been doubted by famous Physisits like Ricardo Carezani.
Dr. carezani postulated the Pico Gravitaton instead as the rain of invisible particles in the Universe which gets absobed by celestial bodies causing the Gravitational phenomenon.
This Gravity process was first postulated by Fatio, one of Isaac Newton's friends. Later the theory was further develpped by L Lesage and now a fully workable model was formulated by Dr. Carezani based on the New revised Theory of Relativity which is a revamp of Einstein General relativity to explain the mechanism of Universal Gravitation.
So the Neutrino question is still a dilemma to science .

Well we estimate a googol to be about the number of elementary particles in our Universe. So less than that.
No number is close to infinity; not even a googolplex.

billions and zillions, since there is an infinite number of stars there is an infinite number of neutrinos.

well, think, there are over 5 billion per i think it was cubic inch, and in the universe there is infinity multiplied by itself, so you would have to keep multiplying the rest of your life, or cause a paradox that would cause the universe to implode. so don't try it.

As Dr. Carl would say
BILLions and BILLions!

they are always being produced in stars
