1) Eclipses occur when one celestial body blocks the light from another. Lunar eclipses happen during a full moon when the Earth casts its shadow on the moon. Solar eclipses occur during a new moon when the moon passes between the Earth and sun. 2) There are three types of lunar eclipses - total, partial, and penumbral - and three types of solar eclipses - total, partial, and annular. 3) Eclipses do not occur every month because the moon's orbit is tilted relative to the Earth's orbit around the sun. Lunar eclipses are more frequent than solar eclipses.

2. Solar and
Lunar Eclipses

3. ECLIPSE
• It occurs when the
source of light is
blocked
• when the sun, Earth and
moon are in one straight
line.

4. Lunar Eclipses
• It occurs when the moon passes
through Earth’s shadow. (Full Moon)

5. • Umbra – The dark inner portion of
the shadow cone.
• Penumbral – the lighter outer
portion of the shadow.

6. Types of Lunar Eclipses
1. Total Lunar Eclipse
2. Partial Lunar Eclipse
3. Penumbral Lunar
Eclipse

7. Total Lunar Eclipse – when the Moon passes
completely into the Umbra, or total shadow of the
Earth.

8. Partial Lunar Eclipse – Occur when the
Moon does not fully move into the Umbra

9. Penumbral Lunar Eclipse –
When the moon passes only through
the penumbra, or partial shadow.
They are barely visible.

10. Solar Eclipses
• It occurs when the moon is directly
between Earth and Sun. (New Moon)

11. Types of Solar
Eclipses
1. Total Solar Eclipse
2. Partial Solar Eclipse
3. Annular Eclipse

12. Total Solar Eclipse – can only
occur if you are at the exact spot within
the moon’s umbra (which isn’t very big).

13. Partial Solar Eclipse – Visible if
you are in the penumbra of the shadow.
Only some of the moon will be shadowed.

14. Annular Eclipse – occurs
when the moon is farthest from
the Earth in its orbit.
This makes the
moon look smaller,
so during the
eclipse you see an
outer ring of light
from the Sun.

15. 2 Kinds of Eclipse
Solar Eclipse
Daytime
When the Moon
casts a shadow on
the Earth, causing
the sun to go dark.
Lunar Eclipse
Nighttime
When the Earth
casts a shadow on
the moon, causing
the moon to go
dark.

16. How often do Eclipses Happen?
• That depends. Lunar Eclipses
happen more often than Solar
Eclipses.
• Everyone who is
experiencing nighttime
during a lunar eclipse can
see it.

17. How often do Eclipses Happen?
• But you have to be at the
exact spot on Earth to see a
Solar Eclipse.
• The spot on Earth is so small, that
the same place only sees a Solar
Eclipse every
350 years*.

18. Why Don’t We See Lunar
Eclipses More Often?
• Well, lunar eclipses don’t happen everyday
because the Moon’s orbit is tilted.
So, during most months, the Moon is above or
below the Earth.
