The side of the orbit of the moon that is closest to the Earth is the lunar perigee.
The first lunar module to orbit the Earth was Apollo 9, launched by NASA in March 1969 as part of the Apollo program. It successfully completed its Earth orbit mission testing key systems in preparation for the upcoming moon landing missions.
The lunar month refers to the time it takes the moon to get back to the same phase (for instance, from one New Moon to the next). The moon needs to get to the same part of its orbit where the Sun is in the same position for an observer on Earth. The Moon has to take another 2.2 days to "catch up."
The movement of the Moon around the Earth is called lunar orbit. It is an elliptical path that the Moon follows as it revolves around the Earth.
No. The earth's shadow on the moon is a lunar eclipse. The moon appears to change shape depending on which part of orbit the earth is in. The sun is almost always shining on one half of the moon (excluding during a lunar eclipse).
The moon's orbit is inclined about 51/2 degrees relative to the plane of the Earth's orbit. For one thing, this explains why we don't have a lunar eclipse at every Full Moon, and a solar eclipse at every New Moon.
A lunar eclipse doesn't happen every month because the Moon's orbit is tilted relative to Earth's orbit around the Sun. This means that most of the time, the Moon passes above or below Earth's shadow, so a lunar eclipse only occurs when the alignment is just right.
A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. This alignment does not happen at every full moon because the Moon's orbit is tilted relative to Earth's orbit, so most full moons occur above or below the Earth's shadow.
The relative concentration of elements on lunar surface compared to earth's surface is known as regolith.
The side of the orbit of the moon that is closest to the Earth is the lunar perigee.
Lunar eclipses occur when the Earth, Moon, and Sun are aligned in a specific way. A lunar eclipse happens only when the full moon passes through Earth's shadow. Since the Moon's orbit is tilted relative to Earth, this alignment doesn't occur every full moon, leading to lunar eclipses being relatively rare events.
No. A lunar eclipse occurs when the Earth passes between the Sun and Moon. Earth's orbit is an intangible imaginary ellipse that does not cast a shadow.

The moon will have a lighted ring around it when it gets directly between the Earth and the sun and can only be seen in a specific region.
The Moon, Sun and Earth are not perfectly aligned every month. Therefore there is not an eclipse every full Moon. The reason the alignment is usually not perfect is that the Moon's orbit is tilted relative to the plane of the Earth's orbit around the Sun.
