SUMMARY

The average distance from Earth to the Moon is 384,403,000 meters. When multiplied by 2π, the result is 2,412,743,158 meters, which represents the circumference of the Moon's orbit. The calculated orbital period of 27 days, 7 hours, and 43.1 minutes converts to 114,186 seconds, leading to a linear speed of 21,130 meters per second. However, the correct conversion indicates that 27 days should equal 2,332,800 seconds, revealing a significant error in the initial time calculation.

PREREQUISITES
  • Understanding of basic orbital mechanics
  • Familiarity with unit conversions, particularly time to seconds
  • Knowledge of circular motion and linear speed calculations
  • Basic mathematical skills for multiplication and division
NEXT STEPS
  • Research the principles of orbital mechanics and Kepler's laws
  • Learn about unit conversion techniques, especially for time
  • Study the calculations of linear speed in circular orbits
  • Explore the significance of the Moon's orbital characteristics in astronomy
USEFUL FOR

Astronomy enthusiasts, physics students, educators teaching orbital mechanics, and anyone interested in the dynamics of celestial bodies.

average distance form earth=384,403,000meters. Multiply by 2π=2,412,743,158meters
orbital period=27days7hours43.1minutes=114,186sec

This gives 2,412,743,158/114,186=21,130meters/sec linear speed.
Wikipedia says 1,021meters/sec

Where's the mistake?

1 day is 86400 seconds, so 27 days can't be 114186 seconds.
 


Cheers. Was hoping it was my mistake.
