Does the sun shine on the moon?

User Avatar

Asked by Wiki User

Yes. What you see when you look at the moon is the sun light on the moon reflecting to you. Except when the Earth is located between the Sun and the Moon [called a total lunar eclipse]. Even then a small amount of light which is defracted through the Earth's atmosphere get to the Moon, but it is diffused light, not shining directly from the Sun to the Moon.

Will the moon be gone one day?

User Avatar

Asked by Wiki User

There are many theories about this, some say a billion years from now, some say never, some even say the moon will eventually crash into the Earth. Nobody knows for sure, although I think it is safe to say whatever will happen it won't happen any time soon.

I agree

(added)

the answer he had was wrong the moon is getting 1 and 1/2 inches away from earth a year so it will be a long time but dont get used to a close moon it will look smaller every year.

Why did kalpana chawla go to the moon?

User Avatar

Asked by Wiki User

No, Kalpana Chawla, an Indian-American astronaut working for NASA, died on February 1, 2003 high above the state of Texas, due to the disintegration of the space shuttle Columbia during the time of its re-entry into the Earth's atmosphere. This accident is known today as the Space Shuttle Columbia Disaster. Neither Chawla nor any astronaut has ever gone to Mars.

Why do things happen in a blue moon?

User Avatar

Asked by Wiki User

The term "blue moon" comes from folklore. Different traditions and conventions place the extra "blue" full moon at different times in the year .In calculating the dates for Lent and Easter the Clergy identify the Lent Moon. It is thought that historically when the moons timing was too early, they named an earlier moon as a "betrayer moon" (belewe moon), thus the Lent moon came at its expected time.Folklore gave each moon a name according to its time of year. A moon that came too early had no folk name, and was called a blue moon, retaining the correct seasonal timings for future moons .The Farmers Almanac defined blue moon as an extra full moon that occurred in a season; one season was normally three full moons. If a season had four full moons, then the third full moon was named a blue moon.Recent popular usage defined a blue moon as the second full moon in a calendar month, stemming from an interpretation error made in 1946 that was discovered in 1999. For example, December 31, 2009 was a blue moon according to this usage.

A "blue moon" is also used colloquially to mean "a rare event", reflected in the phrase "once in a blue moon". The most literal meaning of blue moon is when the moon (not necessarily a full moon) appears to a casual observer to be unusually bluish, which is a rare event. The effect can be caused by smoke or dust particles in the atmosphere, as has happened after forest fires in Sweden and Canada in 1950 and 1951

What are Saturn's moons named after?

User Avatar

Asked by Wiki User

The modern names for the moons of Saturn were suggested by John Herschel in 1847. Naming them after mythological figures associated with Saturn - the Roman god of agriculture and harvest. The then known seven satellites were named after Titans and Titanesses, brothers and sisters of Saturn. In 1848 Lassell proposed that the eighth satellite of Saturn was named Hyperion after another Titan.

When in the 20th century the names of Titans were exhausted, the moons were named after different characters of the Greco-Roman mythology or giants from other mythologies. All the irregular moons (except Phoebe) are named after Inuit and Gallic gods and after Norse ice giants.

Who was the first person to see the moons of Saturn?

Galileo Galei was the first to observe Saturn's rings in 1610 but could not identify them as rings. It was only later in 1655 that Christiaan Huygens was able to prove that they were indeeed rings surrounding the planet.

How long does it take a astronaut to travel around the earth?

It depends on the given orbit, but most astronauts would be on near earth orbit vehicles like the International Space Station (ISS). This orbits the earth once every 91 minutes.

What was the purpose of noel Armstrong walking on the moon?

User Avatar

Asked by Wiki User

There are a lot of purposes, but the main purpose was to prove to the world that the United States really did "Come in peace for all mankind". At the time, some people of the world were worried that we might control the earth from space. We had to prove them wrong. We did that by turning the space race into a series of scientific expeditions.

The reason Neil Armstrong and Buzz Aldrin and the other 10 astronauts who walked on the moon left the lunar module was to help scientists back on earth discover the origin of the moon. It was thought that by finding out the moon's origin, it might shed light on how the earth came to be. In order to do that, Armstrong collected rocks while Aldrin set up 3 scientific experiments. After analyzing all the data, the scientists have yet to come up with a conclusive theory for how the moon formed.

Why are planets and the moon visible in the night sky?

User Avatar

Asked by Wiki User

For the same reason that the stars are visible from Earth - most of the space in between is completely empty, and air is transparent. You can't see stars (other than the sun) during the day because the sun is bright enough that it illuminates the air enough to overpower them, like a single person whispering in a large cheering crowd. The light reflected off of the moon by the sun is, however, bright enough to be seen during the day, though not as clearly as at night. This has a lot to do with the fact that the moon is only 240,000 miles away, while the nearest star is 3 light-years away. Because it orbits Earth, therefore we can see it. ... Well, that's almost correct, but the real reason we can see the Moon from the Earth is that it (the Moon) reflects sunlight during most of its orbit around the earth. When the Moon is between the Earth and the Sun, that period of the Moon's orbit it is essentially 'invisible' since the sun's glare makes the moon impossible to see. We call this period the "New" Moon. If you can picture in your mind the earth revolving around the Sun, and the Moon revolving around the Earth at the same time, you can see how at some point, the Moon is in between Earth and the Sun, and therefor gets 'lost' in the sun's glare.

Can Artificial satellites orbit forever?

User Avatar

Asked by Wiki User

no they can not orbit forever. However, the time that a satellite will remain in orbit is dependent on altitude. Satellites in orbits above about 1500 miles will never decay and fall to Earth, in the expected lifetime of the solar system.


Satellites will not stay in orbit forever. How long they stay up depends on how high they are and the satellite's ballistic coefficient, or mass/frontal area. The drag from our atmosphere decreases with height. Satellites in low orbits, say 500 km, will decay in a few years. At 1000 km they will stay up perhaps a century. Above a few thousand km they would stay practically forever.

Proper disposal of spacecraft is important. A small piece of spacecraft or debris can continue to orbit for a long time, presenting a hazard to operating spacecraft.

The acceleration of gravity depends on how far you are
from the center of the object.

If you stand on the surface of each one, then Jupiter is
the strongest, followed by Earth, Mars, and the Moon
being the weakest.

What are the satellites of the planets?

This is a very vague question. First what planets are you referring to? Second, define "satellites" - Earth's moon is a satellite, but so is every single rock orbiting Saturn. We also send man-made satellites to orbit other planets. Restate your question. And lurn2google.

Does the moon have asteroids in the craters?

User Avatar

Asked by Wiki User

For all practical purposes, the answer is no. The moon provides the Earth with no significant protection from impacts from meteorites, asteroids or comets.

The Moon isn't nearly the same size as the Earth and occupies a tiny fraction of the perimeter of the planet. It's the atmosphere that protects us from small asteroids; they burn up most of the time before they reach the ground. Some are deflected (bounce off) the atmosphere if they hit at a shallow angle. These can appear as fireballs that cross the sky.

For protection, one needs a much larger body that has enough mass to significantly alter the trajectory of an incoming object. There is some evidence that Jupiter has such an effect on objects entering the solar system, but even then one cannot expect that more than a tiny fraction of incoming comets or other objects might be captured or otherwise redirected. Of course, a redirected comet might, by chance, be directed towards a collision as well as away from one.

Does uranus have volcanoes?

User Avatar

Asked by Wiki User

No. Uranus is a gas giant and doesn't have a solid surface like the rocky bodies of the solar system, such as Mercury, Venus, Earth, Mars and many moons. It is theorised to have a solid iron core, but this wouldn't allow for volcanic activity.

Uranus' moon Ariel has many features that are theorised to be caused by volcanic action. These actions are caused by the massive gravity of Uranus squeezing and squashing the moon.

What time does the moon come out in Canada?

User Avatar

Asked by Wiki User

The moon takes about 25 hours to circle the earth, so just like any place in the world, the moon rises about an hour later each night. During the full moon, it rises just about sunset and when the moon is new, it rises with the sun. There are 6 time zones in Canada and this needs to be factored in as well.
