Tidally Locked Planets: How Close to the Star?

Click For Summary
SUMMARY

Tidally locked planets are influenced by their proximity to their parent star, but the process of tidal locking is not solely determined by distance. Factors such as the size of the celestial bodies and their initial rotational speeds play critical roles in the locking process. Therefore, there is no universal distance that guarantees tidal locking; each scenario must be evaluated individually based on these variables.

PREREQUISITES
  • Understanding of tidal locking mechanisms
  • Knowledge of celestial body dynamics
  • Familiarity with gravitational interactions
  • Basic concepts of planetary rotation
NEXT STEPS
  • Research the effects of body size on tidal locking
  • Explore the relationship between initial rotation speed and tidal locking
  • Study gravitational interactions in multi-body systems
  • Investigate specific case studies of known tidally locked exoplanets
USEFUL FOR

Astronomers, astrophysicists, and students studying planetary science or celestial mechanics will benefit from this discussion.

How close must a planet be to its parent star in order for it to be tidally locked?

Tidal locking isn't just determined by position. It takes time for bodies to become locked and it is highly dependent upon the size of the bodies and initial rotations. So I don't think that there is a good general answer to this.
 
Thanks for the answer and the link, it was very helpful.
