The Moon is the only natural satellite of the Earth, and the only celestial body where humans have landed. It is approximately 384,403 kilometers (238,857 miles) away from the Earth, and has an approximate diameter of 3,476 kilometers (2,160 miles).
A lunar distance (LD) is an astronomical measurement of
the distance from the Earth to the Moon. The average distance from
Earth to the Moon is 384,403 kilometers or 238,857 miles,
but the actual distance varies over the course of the orbit of the
moon. Depending on the Moon's location in its orbit, it is between
225,623 and 252,088 miles away from Earth. This is about 30 times
the diameter of the Earth.
Measurements of the lunar distance are made by measuring...
Well, it is obviously Earth. But if you meant the nearest planet
(excluding Earth), it varies from time to time; at their closest
approaches Venus is around 45,000,000 km away to the Earth and Mars
is around 80,000,000 km away from the Earth. But they aren't always
or even usually at their closest approach to Earth. Whether Earth
and the Moon are closer to Venus or to Mars depends on the three
planets' relative positions in their orbits. When Mars is...
The circle of light around the sun is called a Corona. The
corona can usually only be seen during a total solar eclipse. When
this happens it can be seen as an irregularly shaped glow
surrounding the moon.
Theories of the Origin of the Moon
After years of research, studying gamma rays and rock samples
from the Earth and the Moon, it is generally accepted that the ages
of the Earth and the Moon are the same. There are several theories
on its formation.
IMPACT : One theory is that it was formed from the Earth's
crust, following the impact of a large (Mars-sized) asteroid. A
long string of rocky fragments were blown out from the Earth in the
"Life as we know it" is not possible on the Moon because the
Moon has no atmosphere. When people go to live on the Moon, we will
need to provide pressurized habitats in which we can live without a
pressure suit. We will probably also have to live underground,
since the lack of atmosphere also means that there is no protection
from the damaging UV radiation from the Sun.
The Moon also lacks a strong magnetosphere to protect life from
The Moon appears orange-ish when it rises for the same reason
the Sun looks redder at sunset -- the Earth's atmosphere scatters
the shorter, bluer wavelengths of light and more of the reddish
light makes it to your eye. At moonrise, you are seeing the moon
through more of the Earth's atmosphere than when the moon is
overhead, and more of the light at red wavelengths makes it through
the atmosphere to your eye.
Io is close to the massive Jupiter. As a result " tidal forces"
cause large amounts of "flexing" inside Io. This means that Io is
The situation with Earth's moon is not really comparable.
The mean surface temperature during the day is 107° C (226.6°
At night that temperature is negative and drops to -153° C
The maximum surface temperature is 123° C (253.4° F)
The minimum surface temperature is -233° C (-387.4 F)
Technically, yes. However, the tidal effects of moderate-sized
bodies of water such as medium-sized lakes is vanishingly small.
The Great Lakes have very small tidal effects, but rivers are far
more influenced by the flow of the river.
This is because there isn't much water to displace to create a
Oddly enough, the moon's tides also effect solid ground. The
earths crust flexes through a range of about 1 foot over the course
of a day.
Great Answer!! Actually, the moon...
The reflection of sunlight off of the moon's surface can only be
seen when the earth is in the path of the reflected light.
Essentially when the moon is not full, you see part of the moon
that is in shadow. This is the same as looking at a part of the
earth where it is night time, from space.
There have been 12 men to land and walk on the moon.
1: Neil Armstrong
2: Buzz Aldrin
3: Pete Conrad
4: Alan Bean
5: Alan Shepard
6: Edgar Mitchell
7: Dave Scott
8: Jim Irwin
9: John Young
10: Charlie Duke
11: Gene Cernan
12: Harrison Schmitt
Armstrong and Aldrin were from Apollo 11, Conrad and Bean from
Apollo 12, Shepard and Mitchell from Apollo 14, Scott and Irwin
from Apollo 15, Young and Duke were on Apollo 16 and Cernan and
Schmitt were Apollo 17.

Jenaro Gajardo Vera (*November 18, 1919 in Traiguén,
Malleco Province - †May 3, 1998 in Santo Domingo, San Antonio
Province) was an eccentric lawyer, painter and Chilean poet. He
became famous from September 25 of 1953 until his death, as the
legitimate owner of the Moon.
The United Nations 1967 publication "Outer Space Treaty" states
space is the "province of all mankind", and is not subject to
claims on sovereignty by States. As treaties apply to States and
place obligations on States, and...
It depends on the ancient culture you're referring to.
It was believed that a dragon was eating the Sun to symbolise
that famine and disease was coming. The Ancient Chinese who
believed this would form defences around their land to ward off the
dragon, preventing famine and disease from affecting them.
They were also used to forecast predictions for the Chinese
Emperors. Which was a very risky thing to do, because if you got
the Emperor's forecast wrong, you were executed.
The seasons are caused by the axial tilt of the earth with
respect to the sun.
As the earth rotates around the sun, the southern or the
northern hemisphere will get either more sun and less darkness
(thus warmer), or more darkness and less sun (thus colder)
The moon's influence on this would be negligible.
However, the tides are from both the sun and moon's gravity.
When the sun is directly overhead the tides should be highest
(summer). But, since there is an...
Yes, the seasons are a result of Earth's orbit around the
Very true! But there would not be seasons if the Earth did not
tilt on its axis so that part of the Earth received direct
sunlight, and the other part received weaker sunlight at an angle
that had to travel through much more of Earth's atmosphere to
arrive on land. (Or water . . .)
