1. SOLAR ECLIPSE 2017:
WHAT YOU NEED TO KNOW

2. How does it happen?
A total solar eclipse occurs when the disk of the moon appears to completely cover the disk of the sun in the sky.
The sun is 400 times bigger than the moon, but the moon is 400 times closer - strange coincidence!!

3. Here is the difference between a solar and lunar eclipse

4. These heavenly bodies must line up,
but it only occurs about once every 18 months
During totality, the corona becomes visible. You can look at this without glasses - be careful...

5. Types of solar eclipses:

6. How are they different?
Total Eclipse - the shadow falls on a very small area but we see darkness in that shadow
Partial Eclipse - The moon is either too high or too low to cast a shadow on earth so we only see partial
Annular Eclipse - The moon is slightly farther away than usual and the shadow does not reach earth This looks like a “ring of fire”
