Earth-Sun Lagrange Points Distance Query

Click For Summary
SUMMARY

The straight-line distances of the L4 and L5 Lagrange points from Earth depend on the celestial bodies in question. For the Earth-Moon system, the distance to the Lagrange points equals the Moon-Earth distance. In the Sun-Earth system, the distance corresponds to the Sun-Earth distance. Users can utilize the Lagrange Point Finder calculator available at orbitsimulator.com to determine these distances accurately.

PREREQUISITES
  • Understanding of Lagrange points in celestial mechanics
  • Familiarity with the Earth-Moon and Sun-Earth systems
  • Basic knowledge of equilateral triangles in orbital dynamics
  • Ability to use online calculators for orbital calculations
NEXT STEPS
  • Research the mathematical principles behind Lagrange points
  • Learn how to use the Lagrange Point Finder calculator effectively
  • Explore the dynamics of the Earth-Moon and Sun-Earth systems
  • Investigate the applications of Lagrange points in space missions
USEFUL FOR

Astronomers, astrophysicists, students of celestial mechanics, and anyone interested in orbital dynamics and space exploration.

Hi

Does anyone know what the straight line distances of L4 and L5 are from Earth?

Many thanks.

To which L4 and L5 points are you referring to? The Earth-Moon pair or the Sun-Earth pair?
In each case, the chosen Lagrange point and the two celestial bodies form an equilateral triangle.
So in the Earth-Moon case, the Earth-Lagrange point distance is equal to the Moon-Earth distance, and the the Sun-Earth case, it is equal to the Sun-Earth distance.
 
Yes, a quick twirl with a compass and a drawn circle soon showed the error of my ways. This is probably the silliest question I've raised on the forum thus far. I promise to do better next time.
