The document explains the concepts of solar and lunar eclipses, detailing their occurrences based on the alignment of the sun, earth, and moon. It describes types of solar eclipses (total, partial, and annular) and lunar eclipses (total, partial, and penumbral), as well as the frequency of these events. Additionally, it includes specific dates and locations for upcoming 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 Lunar Eclipse
Daytime Nighttime
When the Moon casts
a shadow on the
Earth, causing the sun
to go dark.
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.
