The claim is false: the Sun does not revolve around the Earth. Observations show that the Earth orbits the Sun, while the Sun’s apparent daily motion across the sky is caused by Earth's rotation.

Key points: Geocentric claim contradicted by heliocentric model and extensive astronomical evidence. | Earth orbits the Sun with ~1-year period; the Sun is not revolving around the Earth. | The Sun’s apparent daily path is due to Earth's rotation, not a Sun-centered orbital motion. | Other motions exist (Sun relative to the galaxy), but that does not support the claim.

The claim is factually inaccurate. The Earth revolves around the Sun, not the other way around. The apparent daily motion of the Sun across the sky is caused by the Earth's rotation on its axis.

Key points: The heliocentric model (Sun-centered) is the scientifically established and observationally confirmed model of the solar system | The Earth orbits the Sun once per year (approximately 365.25 days), not the reverse | The Sun appears to move across the sky once per day due to Earth's axial rotation (one rotation per ~24 hours), not solar orbital motion | This has been repeatedly confirmed through multiple independent lines of evidence including parallax measurements, orbital mechanics, and direct observation

The claim states that the Sun revolves around the Earth once per day. This is factually incorrect. Scientific consensus, based on centuries of observation and evidence, confirms that the Earth revolves around the Sun (heliocentrism), completing one orbit approximately every 365.25 days. The apparent daily motion of the Sun across the sky is due to the Earth's rotation on its axis, which takes approximately 24 hours.

Key points: The Earth revolves around the Sun (heliocentric model). | The Sun's apparent daily movement is caused by Earth's rotation. | Earth completes an orbit around the Sun in approximately 365.25 days. | Earth completes one rotation on its axis in approximately 24 hours.

Limitations: This evaluation is based on current scientific understanding, which is well-established and supported by overwhelming evidence.
