what is the difference between a sidereal year and a tropical year?
a sidereal year is 365.24 days, whereas a sidereal year is the time from one axial tilt position to the same position in the next orbit.
a tropical year is 365.24 days, whereas a sidereal year is the time from one axial tilt position to the same position in the next orbit.
a sidereal year is 365 days, whereas a tropical year is 365.24 days.
a sidereal year is one orbit around the sun relative to fixed stars. a tropical year is the time from one axial tilt position to the same position in the next orbit.

Explanation:

A sidereal year is the time it takes for the Earth to complete one orbit around the Sun relative to the fixed stars, approximately 365.24 days. A tropical year is the time from one axial tilt position to the same position in the next orbit, approximately 365.24 days. The key difference is in their reference points: sidereal year (fixed stars) vs. tropical year (axial tilt position).

Answer:

A sidereal year is one orbit around the sun relative to fixed stars. A tropical year is the time from one axial tilt position to the same position in the next orbit.
