Sun and Moon have almost the same angular diameters

• Each subtend an angle ~ ½ degree

• Sun is 400 times larger than the Moon and 400 times further away

Page 3: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Solar and Lunar Eclipses

• Everyone on Dark side of Earth sees a Lunar Eclipse, only a few will see a solar eclipse – shadow sizes!

Page 4: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Slight change in lunar size due to its elliptical orbit around the Earth

• Causes annular and total solar eclipses

Page 5: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Total Solar Eclipse

• Moon’s shadow barely reaches the Earth

Page 6: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Lunar Eclipse

• Earth Shadow easily covers the Moon

Page 7: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Total Solar Eclipse

• Eclipse Path and Partial Eclipse

Page 8: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Solar Eclipses

• Corona, comets and diamond ring effect

Page 9: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Annular Eclipse

• Moon near apogee (too far away)

Page 10: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Lunar Eclipse is often Reddish

• Due to refraction of Earth’s atmosphere

Page 11: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Red Color and Earth’s Shadow

• Red color near edges of shadow

Page 12: Eclipses Lunar and Solar Eclipses. Sun and Moon have almost the same angular diameters Each subtend an angle ~ ½ degree Sun is 400 times larger than the.

Eclipses occur ~ every 6 months

• Line of nodes must point toward the Sun

• The alignment is not exact (eclipse limits)
