The exact number of suns (stars) in the universe is not known. The universe is vast and contains billions of galaxies, each with billions or even trillions of stars. Estimating the total number of stars in the universe is challenging due to its immense scale and our limited ability to observe distant regions.
However, based on current scientific understanding, astronomers estimate that there are approximately 100 billion to 400 billion stars in our Milky Way galaxy alone. Beyond our galaxy, there are billions of other galaxies in the observable universe, and each of these galaxies can contain a substantial number of stars.
Considering the vastness of the universe and the sheer number of galaxies, it is safe to say that there are an enormous number of stars, potentially trillions upon trillions, or even more. The exact count is difficult to determine due to the limitations of our observations and the vast regions of the universe that remain unexplored.
