What is a constellation?
|
A constellation is a group of stars that forms a pattern. Some of the 88 constellations are easier to spot than others. Different constellations are visible from different parts of Earth. Some are visible only from places in the Northern Hemisphere; others can be seen only from the Southern Hemisphere. As Earth orbits the Sun, different constellations become visible as Earth's dark side faces different parts of the night sky. | | The night sky in the Northern Hemisphere, showing some easy-to-spot constellations. |
