Such is the movement of the Moon, it orbits ( revolves) about the Earth in about 28 to 29 days. It also also rotates on its own axis in about the same time.
Because of these movements, we , on Earth, only ever see 61% of the Moon's surface. The remaining 39% has always beeen hidden from direct observation from Earth.
Because the Moon orbits the Earth in an inclined plane, of approximately 5 degrees. from the Earth's solar orbit, and also the Moon, like all other astronomic bodies orbits in an elliptical manner, it is sometimes nearer to us, and sometimes further away. Because of these two characteristics, the Moon's speed about the Earth varies. As a consequence, a lunar orbit can range from 27.33 days to 29.5 days.
Orbital Period (Sidereal) 27.321661 d
(27 d 7 h 43 min 11.5 s[1])
Orbital period (synodic) 29.530589 d
(29 d 12 h 44 min 2.9 s)
What else can I help you with?
When periods of the moons rotation and revolution are equal what is it called?
It is called synchronous rotation when the rotation and orbit take the same amount of time.
How did Galileo's observations of Jupiter's moons challenge Ptolemy?
Ptolemy claimed everything must go around the Earth, but the moons of Jupiter obviously are not going around the Earth.
How does the revolution of the moon affect its appearance?
The moon's revolution is equal to its period of rotation. This means that we see the same side of the moon every day. Also, the moons position compared to the position of the sun makes the phases of the moon.
Why is the lunar cycle longer than the moons period of revolution around the sun?
The lunar cycle, or synodic month, is about 29.5 days, which is longer than the moon's period of revolution around the Earth (approximately 27.3 days, known as the sidereal month) due to the Earth's own motion around the Sun. As the Moon orbits Earth, both bodies are simultaneously moving along their orbits around the Sun. This means that the Moon must travel slightly further to align with the Sun and Earth again, resulting in the longer lunar cycle.
How did Galileo's observations of Jupiter's moons help to show that the geocentric explanation is incorrect?
Galileo observed that Jupiter's moons orbited around Jupiter and not Earth, demonstrating that not all celestial bodies revolve around the Earth. This contradicted the geocentric model, which proposed that all celestial objects orbited around the Earth. Galileo's observations provided evidence for the heliocentric model, in which the Earth and other planets orbit around the Sun.
How moons are in earth?
There are no moons in Earth. But around Earth, yes. There is one.
Are there moons and stars on planet earth?
No, there are not moons or stars ON planet earth, but there are moons and stars around planet earth. == ==
Explain the Moons period of rotation versus period of revolution.?
They are precisely equal.
What is the period of revolution for the moon Charon?
there isn't a correct answer, but i suggest you take a look at NASA s website have a look at Moons, there should be a fact file on the moon Charon. Another viewpoint: I think there is a correct answer. Charon's period of revolution (around Pluto) is about 6.387 Earth days.
When periods of the moons rotation and revolution are equal what is it called?
It is called synchronous rotation when the rotation and orbit take the same amount of time.
What is a year on Io?
Io is a moon of Jupiter. It can have a period of revolution around Jupiter of 1.769 days or you can have Jupiters revolution around the Sun of 11.85920 days.
What is the moons period of rotation?
27.32 Earth days27 1/3 days
How much moons are there around earth?
The earth only has one moon
How many moons are in the earth?
There is no moon IN the Earth. There is one moon ORBITING AROUND Earth.
How did Galileo's observations of Jupiter's moons challenge Ptolemy?
Ptolemy claimed everything must go around the Earth, but the moons of Jupiter obviously are not going around the Earth.
How many moons revolve around earth?
One.
How does the revolution of the moon affect its appearance?
The moon's revolution is equal to its period of rotation. This means that we see the same side of the moon every day. Also, the moons position compared to the position of the sun makes the phases of the moon.
