Before revision: Earth goes through one such complete precessional cycle in a period of approximately 25,772 years or 1° every 72 years, during which the positions of stars will slowly change in both equatorial coordinates and ecliptic longitude.
After revision: Earth goes through one such complete precessional cycle in a period of approximately 26,000 years or 1° every 72 years, during which the positions of stars will slowly change in both equatorial coordinates and ecliptic longitude.
