The number of stars within a specific distance from Earth can be estimated based on astronomical observations and statistical methods. However, it's important to note that our understanding of the distribution of stars in our galaxy is not complete, and the exact number may vary based on ongoing research and new discoveries.
According to current estimates, there are roughly 9,000 to 12,000 stars within 25 light-years of Earth. This estimate includes stars of various types, such as main-sequence stars (like the Sun), red dwarfs, white dwarfs, and others. The exact number can fluctuate as new data becomes available from ongoing surveys and observations of our stellar neighborhood.
It's worth mentioning that the number of stars within a specific distance may also vary depending on the specific criteria used to define the distance, as well as the methods and data sources used for the estimation.
