How to Calculate Angular Diameter of a Galaxy with a Given Diameter?

Click For Summary
SUMMARY

The discussion centers on calculating the angular diameter of a galaxy, specifically noting that if the diameter of a galaxy is given as 150 arcseconds, then the angular diameter is also 150 arcseconds. This conclusion is reached through a straightforward interpretation of the term "angular diameter," which directly correlates to the measurement provided.

PREREQUISITES
  • Understanding of angular measurements in astronomy
  • Familiarity with the concept of arcseconds
  • Basic knowledge of celestial objects and their dimensions
  • Awareness of astronomical terminology
NEXT STEPS
  • Research the significance of angular diameter in astrophysics
  • Explore the relationship between physical size and angular size of celestial objects
  • Learn about measuring distances to galaxies using angular diameter
  • Investigate tools for visualizing celestial objects and their dimensions
USEFUL FOR

Astronomy enthusiasts, astrophysicists, and students studying celestial measurements will benefit from this discussion.

If I know the diameter of a galaxy in the sky is 150 arcseconds,

how do I find the angular diameter?
