Question

How many stars in the sky​

Answer 1

Answer:

While there are between 100 billion and 400 billion stars in our galaxy, our eyes can only see stars brighter than magnitude 6 to 6.5. That corresponds to between about 3,500 and 4,500 stars on any given night in a single hemisphere under perfect conditions.

Answer 2

The star forms in the form of a nebula during its formation. The nebula is a dust and gas cloud. The greater the star, the hotter and higher the temperatures it contains. A star, for example, is the Sun.

Explanation:

• In the universe, there are around 125 billion galaxies. It is self-evident that scientists will be unable to count the number of stars in each galaxy; doing so will be practically impossible.
• As a result, scientists estimate the number of stars in a galaxy and use that estimate to calculate the total number of stars in the universe.
• There could be billions of stars in a galaxy, and millions of galaxies in the universe. All of this cannot be accomplished simply by counting each star with a telescope because there are millions of stars in the universe, the majority of which are not even bright enough to be seen.
• Satellites that are launched into space also make estimates regarding the number of stars.
