Of all the stars in our galaxy, how much of them belong to clusters?? Is our sun rare in terms of not belonging to any cluster? I can't find any sources on that
Percent of stars in our galaxy that belong to clusters?
In summary, based on Wikipedia's information, it appears that globular clusters make up a significant percentage of the stars in our galaxy, with an estimate of around 10%. Additionally, there are also open clusters to consider.

Well, Wikipedia says "Our galaxy has about 150 globular clusters" so based on that and also its assertion that "Globular clusters, or GC, are roughly spherical groupings of from 10,000 to several million stars packed into regions of from 10 to 30 light years across." it certainly looks like they could make up a significant percentage of the stars in the Milky Way but even w/ an average of 1,000,000 stars per cluster it looks like the percentage would be in the 10% range.

an don't forget about the many open clusters as well
1. What is the estimated percent of stars in our galaxy that belong to clusters?
The estimated percent of stars in our galaxy that belong to clusters is approximately 10%. This means that out of the billions of stars in our galaxy, around 10% of them are part of a star cluster.
2. How do scientists determine the percent of stars in our galaxy that belong to clusters?
Scientists use various methods to determine the percent of stars in our galaxy that belong to clusters. One method is by observing the distribution of stars in our galaxy and identifying clusters based on their proximity to each other. Another method is by studying the chemical composition of stars and identifying clusters based on similar compositions.
3. Are all stars in our galaxy part of a cluster?
No, not all stars in our galaxy are part of a cluster. While approximately 10% of stars in our galaxy belong to clusters, the remaining 90% are considered solitary stars that exist on their own.
4. Do all clusters in our galaxy have the same number of stars?
No, not all clusters in our galaxy have the same number of stars. The number of stars in a cluster can range from a few dozen to several hundred thousand. This depends on the size and age of the cluster, as well as the rate at which stars are formed within it.
5. What is the significance of knowing the percent of stars in our galaxy that belong to clusters?
Knowing the percent of stars in our galaxy that belong to clusters helps us understand the formation and evolution of our galaxy. It also gives us insight into the processes that occur within star clusters, such as star formation and interactions between stars. Additionally, studying star clusters can provide valuable information about the overall composition and structure of our galaxy.
