Question 23

A constellation is defined as a group of stars forming a recognizable pattern. Option a is too narrow (only zodiac), c is astrological (not scientific), d is incorrect (single star).

The IAU currently recognizes 88 constellations. Other options (78, 28, 108) are incorrect.

Sirius is the brightest star in the sky. Polaris is the North Star (not brightest), Deneb is less bright, and "The North Star" is Polaris.

Answer:

b. a group of stars that forms a recognizable pattern
