Distance Earth-Saturn: Solving the Doppler Effect

Click For Summary
SUMMARY

The distance between Earth and Saturn, when both are aligned on the same side of the Sun, is 8.54 AU. Given that Earth's semi-major axis is 1 AU and Saturn's semi-major axis is 9.54 AU, the calculation is straightforward: 9.54 AU - 1 AU = 8.54 AU. This distance is crucial for understanding the Doppler effect in astronomical observations, as it directly influences the frequency shifts of light from these celestial bodies.

PREREQUISITES
  • Understanding of astronomical units (AU)
  • Basic knowledge of the Doppler effect
  • Familiarity with celestial mechanics
  • Ability to perform simple arithmetic operations with astronomical distances
NEXT STEPS
  • Research the implications of the Doppler effect in astronomy
  • Learn about the calculation of distances in the solar system using Kepler's laws
  • Explore the significance of semi-major axes in planetary orbits
  • Investigate how distance affects light frequency and wavelength
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in understanding the relationship between distance and the Doppler effect in celestial observations.

I need to find what the distance between Earth and saturn would be if they were both in a straight line with the sun (both on the same side of the sun).

The problem I'm trying to solve involves the doppler effect, and I can work it out if I know that distance. Does anyone know what it is, or where I could look to find out?

Google/Wikipedia is your friend.

Earth's semi-major axis is 1AU and Saturn's semi-major axis is 9.54AU.

So if they were inline on the same side of the Sun, they would be 8.54AU apart, where 1AU is ~1.5E8km.
 
Thanks :smile:
