Stars in constellations quick check the international astronaut nomical Union i a u defines a constellation by its brightest star boundary star pattern Greek name

Answer 1

The International Astronomical Union (IAU) defines a constellation as a specific area of the celestial sphere, not just by its brightest star or pattern. There are 88 officially recognized constellations. Each constellation has a defined boundary, and they are often named after figures from mythology, many of which are of Greek origin. The shapes and patterns formed by stars within these defined areas are often referred to as asterisms.

If you're looking for a quick check on some key points:

1. **Definition**: A constellation is a designated area of the celestial sphere.
2. **Number**: There are 88 officially recognized constellations.
3. **Naming**: Most constellations are named after figures from mythology, with many names derived from Greek.
4. **Star Patterns**: The stars within a constellation can form recognizable patterns or shapes, but the constellations themselves are defined by boundaries, not just by the patterns they create.
