SUMMARY

The current consensus among professionals is that Earth's distance from the galactic center is approximately 26,000 light-years, a figure supported by recent studies. This estimate aligns with values reported since the early 1990s, confirming its reliability. Additionally, the Milky Way galaxy measures about 100,000 light-years in diameter, contrary to earlier misconceptions regarding its size. These findings are crucial for understanding our position within the galaxy.

PREREQUISITES
  • Understanding of galactic structure and measurements
  • Familiarity with astronomical distance scales
  • Knowledge of black hole properties and their significance
  • Basic concepts of the Milky Way's dimensions
NEXT STEPS
  • Research the methods used to measure galactic distances, such as parallax and standard candles
  • Explore the characteristics and significance of supermassive black holes
  • Learn about the Milky Way's structure and its components, including spiral arms and bulges
  • Investigate historical changes in the understanding of galactic measurements since the 1990s
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in the structure of the Milky Way and the dynamics of black holes will benefit from this discussion.

This Sciam article states, 'Both papers provide new, closely related estimates for the mass of the suspected black hole and the distance between our sun and the galactic center, roughly 26,000 light-years away.'

Is this number generally accepted by professionals now? If I recall, Earth is 2/3 out from the galactic center and the milky way is 200,000 ly wide. I don't know, what is the popular sentiment today?

Your memory is off by a factor of two on the size of the Milky Way: It is about 100,000 light years across.

That 26,000 light year number is more-or-less consistent with values reported since the early 1990s.
