Relationships Between Sun, Earth, Moon by grace ray on Prezi
The sun and moon appear the same size in Earth’s sky because the sun’s diameter is about times greater – but the sun is also about times farther away. At this particular moment in Earth’s history – although the sun’s diameter is about times larger than that. The average distance between Earth and Moon is approximately 30 The Sun happens to be times the Moon's diameter, and times as far away. poorly compared to Earth, which always has highly-reflective clouds. That Sun is times as far from Earth as is our Moon. At the average A comparison of the sizes of the Sun, Earth, and Jupiter. The Sun is.
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. Uncle Milton Moon in My Room.
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. See the moon phases, and the difference between a waxing and waning crescent or gibbous moon, in this Space.
See the full infographic. This spurred a series of uncrewed missions by both the Soviet Union and the United States to observe the moon's surface.
Many of these first probes were failures or only partially successful. However, over time, these early probes returned information about the moon's surface and geological history. Luna 2 was the first spacecraft to impact the moon in The first soft landing was achieved inby Luna 9. The United States sent astronauts to the moon's orbit and surface in the s and s.
The first mission to the moon was inwhen the Apollo 8 astronauts orbited it. InApollo 11 landed the first astronauts on the moonundoubtedly the most famous of NASA's achievements, followed by five more successful missions and one, Apollo 13, that didn't make to the moon. Their efforts returned lbs.
It remains the only extraterrestrial body that humanity has ever visited. Scientists continue to study the rocks, and have made new discoveries as technology improved. For example, inwater was found in samples from Apollo 15, 16 and 17 — an interesting find given that previous analyses showed these rocks were quite dry.
In early January when the Earth is at perihelion Earth's closest point to the Sun in each orbitEarth comes within In July, when Earth reaches aphelion its furthest point from the Sunit recedes to a distance of Remember, this variation in distance is NOT the cause of our seasons on Earth.

This is a misconception held by many students, so beware of this when discussing this topic with your students. During the Apollo space program that sent astronauts to the Moon, the trip from Earth to the Moon took slightly more than two days. That Sun is times as far from Earth as is our Moon.
At the average speed of the Apollo flights, a trip to the Sun would take more than two years. At that speed, a journey to the Sun from Earth would last more than 17 years. It could circle the Earth seven times in a single second. Nevertheless, light takes 8 minutes 19 seconds to make the trip from the Sun to Earth.
This is a significant time lag, and means that we don't see changes that occur on the Sun until several minutes after they actually happen. Earth's diameter is 12, km 7, The diameter of the Sun is thus times as great as the Earth's diameter. In other words, you could line up Earths across the face of the Sun. The Sun is about times as large as Earth, in terms of diameter.
