The Texas Astronomical Society of Dallas
wishes to partner and participate with individuals, groups, schools,
towns, and all forms of organizations to celebrate the 2024 total solar
eclipse. This majestic celestial event will be, for many, a once-in-a-lifetime
opportunity that is certain to inspire wonder about our place in the
universe. We in North Texas are fortunate to sit on the path of totality,
and with this opportunity we will provide education to whoever desires
Within this outreach kit, you will
find in-depth information and ample resources to help you have a successful
total solar eclipse
you have questions about any of the content provided, or require
further information regarding the science of eclipses,
safety, or planned events,
please feel free to reach out to us at firstname.lastname@example.org, and
follow us on Facebook and Instagram to stay up to date
on our club’s events,
news, and general membership meetings. And of course you can
become a member of TAS at texasastro.org.

- The Earth is ~4 times as wide as the Moon (Diameter)
- There are ~30 Earth diameters distance between the Moon and Earth
- The Sun is about ~100 Earth Diameters wide (109)
- The Sun is ~400 times the distance between the Earth and Moon
- The Sun is ~400 times as wide as the Moon
- The Moon moves through the sky about 12 degrees each day to the east.
For the April 8, 2024 Eclipse ...
- 31 million people live in the path of the total solar eclipse, almost
10% of the US population. This is three times more people than
in the 2017 solar eclipse!
- 50% of the US population lives within 250 miles of the path of totality.
- On the day of the total solar eclipse (April 8th), the the five
naked eye planets will be in the sky.
- The moon will be seen between the sun and the earth
- Venus will be at -3.9 mag 15 degrees
west of the sun.
- Saturn and Mars will be first magnitude 1.5 degrees apart
about 35 degrees west of the sun. So, they will be visible that
sunrise, but difficult to see during totality.
at about magnitude -2.0, 30 degrees east of the sun and visible that
evening after sunset.
- Comet 12P/Pons-Brooks will be about 6 degrees south-west of
Jupiter between Jupiter and the Sun during the eclipse.
- Someday, we will no longer have solar eclipses as the moon is moving
a few centimeters away from Earth every year.

Total Solar Eclipse happens roughly every year and a half somewhere
isn't there an eclipse every month?
eclipse occurs at least twice a year. A total solar eclipse can
at the new moon phase. To see a solar eclipse, you have to be
on the sunny side of earth, but the same spot on earth will see
eclipse only about once every 375 years! There are at least two
solar and two lunar eclipses (total or partial) every year visible
somewhere on earth.
The reason why there is not a solar eclipse every month is because
orbit forms a plane that is tilted about 5 degrees
relative to the plane of the earth's orbit. This means that most of the
time the moon is either above or below the plane of the earth's
Eclipses occur only when all three, sun, moon, and earth, line
up in a row.
To see a lunar eclipse, you have to be on the nighttime side
of the earth. A solar eclipse occurs on the daytime side of
a solar eclipse, the moon's shadow extends about 400,000 km
(248,500 miles) past or behind the moon.
The moon's diameter (length of the straight line through the
middle, widest part, of the moon) is about 400 times smaller
than the sun's
diameter; however, the moon is also 400 times closer to the
earth than the sun. This makes the apparent size of the moon appear
the same as
the sun. When the moon passes across the middle of the sun,
it just covers up the sun's disk in the sky as viewed from earth.

eclipse to an observer on the earth who is just under that

In 2017, the moon's shadow (umbra) was about 70 miles wide
and crossed 14 states across the United States from the
Atlantic Ocean. The maximum eclipse was about 2 1/2 minutes
In 2024, the shadow of the moon will be about 100 miles wide
and will travel across the United States at about 2,000 miles
totality will last about 4 minutes and 20 seconds in Texas
and this duration also depends on where the observer is inside
totality. The maximum possible length of totality is 7 minutes
32 seconds. The
2024 solar eclipse is the last total solar eclipse in Texas
for this century. The next total solar eclipse in the United
