🔍 Key Concepts

• First Point of Aries as the origin for right ascension in celestial navigation and astronomy • Relationship between the First Point of Aries and the vernal equinox • Approximate calendar dates of the equinoxes vs the solstices

💭 Think About

• Which two of the four dates given are equinoxes, and which two are solstices? • Is the First Point of Aries associated with when the Sun is farthest north/south, or when day and night are roughly equal? • Historically, which zodiac sign is linked to the start of spring in the northern hemisphere?

✅ Before You Answer

• Identify which dates correspond to equinoxes (not solstices) • Recall that the First Point of Aries marks the zero point of right ascension at the spring equinox • Eliminate any choice that is clearly tied to summer or winter solstice rather than an equinox
