🔍 Key Concepts

• Named navigation stars commonly used in marine celestial navigation • The constellation also known as the Northern Cross • The bright star triangle formed by Vega, Altair, and Deneb in summer skies

💭 Think About

• Think about which constellation is nicknamed the Northern Cross and which bright star marks the tail of that figure. • Recall the three bright stars that form the Summer Triangle and match each one to its constellation. • Eliminate constellations better known for other key stars, such as the Big Dipper or the Great Square, to narrow your options.

✅ Before You Answer

• Verify which option is associated with the Northern Cross shape in the sky. • Confirm which constellation contributes Deneb to the Summer Triangle asterism. • Make sure you are not mixing up Deneb with stars from Ursa Major (Big Dipper) or Pegasus (Great Square).
