Part 2 & 3- Constellations & Stars

Part 2- Constellations

2. Describe the location and movement of individual stars and groups of stars (constellations) as they move through the night sky. 

3. Recognize that the apparent movement of objects in the night sky is regular and predictable, and explain how this apparent movement is related to Earth's rotation. 

The Earth is tilted by 23.5 degrees, this attributes to:

• The changes in seasons

• The amount of daylight Earth receives during the seasons

• Why the Sun appears to be lower in the sky in winter compared to summer. 

By now we should know that constellations appear to move across the night sky throughout the night, because the Earth is spinning on it's axis. 

From left to right a constellation may look like this throughout the night at 9:00 pm, 12:00 am, 3:00 am, and 6:00 am.

et me blow you're mind! This also happens throughout the year too! 

The position of a constellation will change throughout the seasons, but you have to observe that constellation at the same time of night (ex. 12:00 am).

From left to right a constellation may look like this throughout the seasons at the same time of night.

This happens because Earth not only spins on it's axis, it also orbits around the Sun. Kind of a double spin, enough to make your head spin!
