SUMMARY

The distribution of stars and galaxies reveals that while there are stars outside of galaxies, the vast majority reside within them. Current estimates indicate there are approximately 100 billion galaxies visible from Earth, each containing around 100 billion stars. Although planets are believed to be common around stars, the exact star-to-planet ratio remains uncertain due to limited observational data. This discussion highlights the need for further research to understand the dynamics of star and planet formation within the universe.

PREREQUISITES
  • A basic understanding of astrophysics concepts
  • Familiarity with galaxy formation theories
  • Knowledge of observational astronomy techniques
  • Understanding of planetary formation processes
NEXT STEPS
  • Research the methods of galaxy classification and their characteristics
  • Explore the latest findings on exoplanet discovery techniques
  • Study the implications of the star-to-planet ratio on cosmic evolution
  • Investigate resources on artificial universe simulations and modeling
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in the structure of the universe and the formation of celestial bodies.

Ho :),
I would like to know how exactly stars and galaxies are spread out throughout the universe.

Are stars only found within galaxies?

How many stars are without any planets?

Whats the average number of planets in a star with planets?

Whats the maximum/minimum number of planets with stars?

Whats the galaxy:star ratio?

Basically I would like to know everything required in order to create an artificial universe.

Thanks :)

Regards

Q

PS

If there's a good linke/document/book on this thatd be great.

While there are definitely stars outside of galaxies, the vast, vast majority are within them. There are approximately 100 billion galaxies visible from Earth, and they, on average, have approximately 100 billion stars each.

We also expect that planets are the norm, but we don't actually know how common they are. Our observations of planets are so far very limited.
 
Most of your star/planet ratio questions we just don't know yet, although they do seem more common than was originally thought.
