🔍 Key Concepts

• Tropical year – based on the cycle of seasons and the Sun’s apparent passage from one vernal equinox to the next • Sidereal year – based on Earth’s orbit relative to the fixed stars, not the equinox • Difference in length: which two ‘years’ are closest, differing by only about 20 minutes?

💭 Think About

• First, recall what each option means: which one is measured against the stars, which against the Sun and seasons, and which are just other names for the same thing? • Ask yourself: the tropical year is tied to the equinoxes and the seasons. Which other ‘year’ type is slightly longer because it ignores the slow shift of the equinox (precession)? • Eliminate any choices that are just alternative names for the tropical year itself—those would not differ by 20 minutes.

✅ Before You Answer

• Verify which ‘year’ is defined as the time it takes Earth to return to the same position relative to the fixed stars • Check which terms are effectively synonyms: is an equinoctial year another name for the tropical year, or something else? • Confirm which pair has a known difference of roughly 20 minutes in length, with the star‑based year being slightly longer.
