moons (the largest and most visible from Earth), and the largest moon in the solar diameter. Painting by Monica Aiello: The Flight of Ganymede. Acrylic, ink. The moon's diameter is about one-fourth that of Earth's. the real thing, but that will maintain the size relationship between the three objects. Let's take a look at the diameter first. The diameter of the Moon is 3, km. Now, let's compare this to the Earth. The diameter of the Earth is.

These include that the Earth captured the moon, that the moon fissioned out of the Earth, or that Earth may even have stolen the moon from Venusaccording to a recent theory.

Planet Earth compared to other planets and stars in size.

Internal structure The moon very likely has a very small corejust 1 to 2 percent of the moon's mass and roughly miles km wide. It likely consists mostly of iron, but may also contain large amounts of sulfur and other elements.

Its rocky mantle is about miles 1, km thick and made up of dense rocks rich in iron and magnesium. Magmas in the mantle made their way to the surface in the past and erupted volcanically for more than a billion years — from at least four billion years ago to fewer than three billion years past.

The crust on top averages some 42 miles 70 km deep. The outermost part of the crust is broken and jumbled due to all the large impacts it has received, a shattered zone that gives way to intact material below a depth of about 6 miles 9.

Surface composition Like the four inner planetsthe moon is rocky. It's pockmarked with craters formed by asteroid impacts millions of years ago. Because there is no weather, the craters have not eroded.

The average composition of the lunar surface by weight is roughly 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, 3 percent calcium, 3 percent aluminum, 0. Orbiters have found traces of water on the lunar surface that may have originated from deep underground. They have also located hundreds of pits that could house explorers who remain on the moon long-term.

Our Changing Moon ] Ongoing observations from the Lunar Reconnaissance Orbiter LRO showed that water is more abundant on slopes facing the lunar south polealthough scientists do caution that the water quantity is comparable to an extremely dry desert. Meanwhile, a study suggested the moon's interior could be abundant in watertoo.

And without much of an atmosphere, heat is not held near the surface, so temperatures vary wildly. Daytime temperatures on the sunny side of the moon reach degrees F C ; on the dark side it gets as cold as minus F minus C. Average distance from Earth: To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust.

High tides are when water bulges upward, and low tides are when water drops down. High tide results on the side of the Earth nearest the moon due to gravity, and it also happens on the side farthest from the moon due to the inertia of water.

Low tides occur between these two humps. The pull of the moon is also slowing the Earth's rotation, an effect known as tidal braking, which increases the length of our day by 2.

The energy that Earth loses is picked up by the moon, increasing its distance from the Earth, which means the moon gets farther away by 1. The moon doesn't escape from the interplay unscathed.

A new study suggests that Earth's gravity stretched the moon into its odd shape early in its lifetime. Lunar eclipses During eclipses, the moon, Earth and sun are in a straight line, or nearly so. A lunar eclipse takes place when Earth gets directly or almost directly between the sun and the moon, and Earth's shadow falls on the moon.

A lunar eclipse can occur only during a full moon. Total Lunar Eclipse of Oct. A solar eclipse can occur only during a new moon. Solar eclipses are rare in a given location because the shadow of the moon is so small on the Earth's surface. The last total solar eclipse in the United States happened in Aug. Skywatcher Nick Rose took this photo of the total lunar eclipse Dec. Nick Rose Seasons The Earth's axis of rotation is tilted in relation to the ecliptic plane, an imaginary surface through Earth's orbit around the sun.

This means the Northern and Southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons.

The tilt of Earth's axis is about As such, the moon virtually has no seasons. This means that some areas are always lit by sunlight, and other places are perpetually draped in shadow.

The Greeks also believed the dark areas of the moon were seas while the bright regions were land, which influenced the current names for those places — "maria" and "terrae," which is Latin for seas and land, respectively. The pioneering astronomer Galileo Galilei was the first to use a telescope to make scientific observations of the moon, describing in a rough, mountainous surface that was quite different from the popular beliefs of his day that the moon was smooth.

This spurred a series of uncrewed missions by both the Soviet Union and the United States to observe the moon's surface. Tilt the beaker slightly. Gently fill the beaker with rubbing alcohol. The alcohol is less dense than the water and therefore will float on the surface of the water.

Slowly add a teaspoon of oil to the beaker. The oil will form spheres where the water and alcohol meet. Questions to ask and discuss: What motion does Earth go through once a year?

It revolves around the sun once every year Since Earth revolves around the sun, is Earth or the sun the center of the solar system? If the oil spheres represent the planets in the solar system, where would the sun be located? In the center of the beaker. How many planets are in our solar system?

Like Earth, all the planets revolve around the sun. Do you think it takes all the planets one year days to make this journey? How big is Earth, moon, and sun? Ask students to estimate the diameter of Earth, sun, and moon.

Using the Earth and Moon Diagram, show them a circle of paper that is 4" 10 cm in diameter. This will represent Earth. Now, ask them how big a paper circle you need to represent the moon. Have the students cut out a circle the size they think the moon should be and compare their estimates.

Give them the approximate diameters of the real moon and Earth. Therefore, the paper moon should be 1" 2. Cut out a paper moon of that size.

Have students estimate how big to make the sun before reviewing the size of the actual sun. Approximate diameter of the real sun. How many times bigger will the paper sun need to be than the paper moon of 1"?
