8 THE MOON:
Is a satellite of the Earth and orbits around it.

Is the only object in space that man has ever visited. One reason is that the Moon is much closer to Earth than the other planets (on average about 240,000 miles).

Has a diameter of about 3,476 kilometers.

Takes 27.3 days to make one orbit around the Earth. It also takes the Moon 27.3 days to complete one rotation on its axis.

Surface has many craters on it. These were formed by meteor crashes a long time ago.

Causes many of the tides in the Earth's oceans. This is because of the gravity force between the Earth and Moon.

Can be seen clearly with your eyes, binoculars, or a telescope.

15 Moonrise from Earth:
The moon rises and sets every day, appearing on the horizon just like the sun. The time depends on the phase of the moon. It rises about 30 to 70 minutes later each day than the previous day, so the moon is out during daytime as often is it's out at night. At the time of the new moon, the moon rises at about the same time the sun rises, and it sets at about the same time the sun sets. As the days go by (as it waxes to become a crescent moon, a half moon, and a gibbous moon, on the way to a full moon), the moon rises during daytime (after the sun rises), rising later each day, and it sets at nighttime, setting later and later each night. At the full moon, the times of moonrise and moonset have advanced so that the moon rises about the same time the sun sets, and the moon sets at about the same time the sun rises. As the moon wanes (becoming a half moon and a crescent moon, on the way to a new moon), the moon rises during the night, after sunset, rising later each night. It then sets in the daytime, after the sun rises. Eventually, the moon rises so late at night that it's actually rising around sunrise, and it's setting around sunset. That's when it's a new moon once again.
16 [LINK]: TIDES
Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side). Since the earth is rotating while this is happening, two tides occur each day. Isaac Newton (1642 -1727) was the first person to explain tides scientifically. His explanation of the tides (and many other phenomena) was published in 1686.
Spring Tides
Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.
The eccentricity of the orbit of the moon in this illustration is greatly exaggerated.

Neap Tides

Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.
17 [LINK]: Lunar Eclipses
A lunar eclipse occurs when the Earth's shadow falls on the moon. Lunar eclipses occur, on average, about every 6 months.

Types of Lunar Eclipses
• Total Eclipse - When the entire moon enters the Earth's umbra (the darkest part of its shadow), this is called a total eclipse.
• Partial Eclipse - When only part of the moon enters the Earth's umbra, this is called a partial eclipse.

Duration of Lunar Eclipses
During an average total lunar eclipse, the moon is within the Earth's umbra for about an hour. This is called totality.

Frequency of Lunar Eclipses
Since the plane of the moon's orbit is inclined about 5°: from the plane of the Earth's orbit, lunar eclipses are relatively infrequent. There are about two lunar eclipses each year (visible somewhere on Earth).
