“The Earth completes one orbit around the Sun in approximately 365.25 days.”
Authoritative astronomy sources support the claim as a rounded approximation. NASA states that Earth takes about 365.25 days to complete one trip/orbit around the Sun. More precise values depend on which kind of year is meant: the sidereal year, Earth’s orbit relative to the fixed stars, is about 365.256 days, while the tropical/solar year used for seasons and calendars is about 365.2422 days. Both round to approximately 365.25 days for ordinary purposes.

1. Facts About Earth
SupportsNASA says it takes 365.25 days for Earth to complete one trip around the Sun.
2. What Is a Leap Year?
SupportsNASA explains that Earth takes approximately 365.25 days, or about 365 days and 6 hours, to orbit the Sun.
3. Earth Fact Sheet
Mostly supportsNASA’s fact sheet gives Earth’s sidereal orbit period as 365.256 days, a more precise value that rounds closely to 365.25 days.
4. Weather Glossary: Y's
ContextNOAA distinguishes the sidereal year, 365.2564 mean solar days, from the tropical year, 365.2422 mean solar days. This explains why sources may list slightly different values.
5. Chapter 2: Reference Systems
ContextNASA gives Earth’s revolution around the Sun relative to the stars as 365 days, 6 hours, 9 minutes, consistent with a sidereal year of about 365.256 days.
Limitations
• The claim is an approximation; the exact number depends on whether one means sidereal year, tropical year, or a calendar-year convention.
• Earth’s orbit is perturbed by other bodies, so a single simple number is a rounded educational value rather than an exact constant.
