What is the minimum angular distance from the Sun for Venus to be visible?

Click For Summary
SUMMARY

The minimum angular distance from the Sun for Venus to be visible to the naked eye is approximately 10 degrees, although visibility can vary based on atmospheric conditions and the position of Venus relative to the Sun. Observations indicate that Venus can be seen shortly after sunset or before sunrise when it is at an altitude of around 5 to 6 degrees. Factors such as haze can significantly impact visibility, making it essential to consider local weather conditions when attempting to view Venus near the Sun.

PREREQUISITES
  • Understanding of angular distance in astronomy
  • Familiarity with celestial navigation concepts
  • Knowledge of atmospheric effects on visibility
  • Experience with using astronomical observation tools
NEXT STEPS
  • Research the effects of atmospheric conditions on celestial visibility
  • Learn about the phases of Venus and their impact on observation
  • Explore tools for tracking celestial bodies, such as SkySafari or Stellarium
  • Investigate the role of altitude in observing planets near the Sun
USEFUL FOR

Astronomy enthusiasts, amateur astronomers, and anyone interested in observing celestial events involving Venus and the Sun.

NOT at all!

BTW, I think ten degrees would be to close to see, but I'm looking for a more informed opinion.
 
kaleidoscope, On Sky and Telescope's website you can search for more detailed facts about viewing Venus near the sun. Here is a report from where you may begin:

“To the left it is Venus as photographed last evening just after sundown. It had an altitude of only 6°at sunset (lat. 38° Ν) and was visible to the naked eye. This morning i tried to locate it again (altitude 5°at sunrise from my site). Managed to photograph it (right photo), but this time it wasn't visible to the naked eye due to haze.”

I would think that the answer would depend upon whether Venus is nearly behind or in front of the sun, and that it would be visible sooner if behind since it would be more fully illuminated.
