SUMMARY

The discussion centers on the movement of stars across the sky in the presence of Earth's atmosphere. It is established that stars, being located far beyond the atmosphere, do not experience physical movement due to atmospheric conditions. However, the atmosphere does affect the light from stars, causing phenomena such as refraction, which can alter their apparent position and brightness. This understanding clarifies that while stars maintain a constant trajectory, their visual representation can change due to atmospheric effects.

PREREQUISITES
  • Understanding of basic astronomical concepts, particularly star movement.
  • Knowledge of atmospheric physics, specifically light refraction.
  • Familiarity with the principles of optics as they relate to celestial observations.
  • Basic comprehension of Earth's atmosphere and its layers.
NEXT STEPS
  • Research the principles of light refraction in Earth's atmosphere.
  • Study the effects of atmospheric conditions on astronomical observations.
  • Explore the concept of apparent motion versus actual motion in celestial bodies.
  • Learn about the different layers of the atmosphere and their impact on stargazing.
USEFUL FOR

Astronomy students, educators, and anyone interested in understanding the effects of Earth's atmosphere on celestial observations will benefit from this discussion.

Homework Statement


In the absence of an atmosphere, a star moves across the sky from horizon to horizon at a constant speed. how does the star appear to move in the presence of an atmosphere?

I would say that in the presence of an atmosphere the star don't move at all because of all the air and magnetic force. can someone tell if I'm right or wrong?

Stars are very far outside the Earth's atmosphere. They are not affected by it. The question is asking the atmosphere affects the light from the star.
