Nibiru Criticism
The existence of Nibiru as described by Zecharia Sitchin is not supported by mainstream astronomy.
Astronomical Objections
- Orbital Mechanics — A planet with a 3,600-year orbit as described would be detectable
- Gravitational Effects — Such a planet would cause observable perturbations in the orbits of outer planets
- Infrared Signatures — A large planet would be visible in infrared surveys
- No Evidence — Decades of astronomical surveys have found no evidence of such a planet
Planet Nine
The scientific search for “Planet Nine” (Batygin & Brown, 2016) is sometimes confused with Sitchin’s Nibiru, but they are different concepts:
- Planet Nine: Neptune-sized, 10,000–20,000-year orbit
- Nibiru (Sitchin): Earth-sized, 3,600-year orbit
