could we survive without the moon?

Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That's because the Earth's rotation slows down over time thanks to the gravitational force -- or pull of the moon -- and without it, days would go by in a blink.

Sources. One source of the lunar atmosphere is outgassing: the release of gases such as radon and helium resulting from radioactive decay within the crust and mantle. Another important source is the bombardment of the lunar surface by micrometeorites, the solar wind, and sunlight, in a process known as sputtering.

Good news: Oxygen on the Moon is abundant. The lunar crust is 40 percent oxygen by mass, and NASA scientists have lots of ideas for how to extract it. Simply heating lunar soil to very high temperature causes gaseous oxygen to emerge. (For more information on this, see Science@NASA's Breathing Moonrocks.)

Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.

The Moon is an astronomical body that orbits the Earth as its only permanent natural satellite. Basically, the Moon is neither a star nor a planet, though it is always by the Earth's side and rotates with us synchronically as a satellite.

NASA Says Moon May Have More Water Than the Great Lakes. The North American Great Lakes have some competition. ... Fortunately, there aren't any lakes on the moon ready for sucking. The study, highlighted by iTWire, says the water is located in the moon's interior, and is indigenous to the moon.

The Moon can only be seen as a result of the Sun's light reflecting off it. It does not produce any light of its own.

Survival experts apply the "rule of threes" to lasting without essentials. You can go about three weeks without food, three days without water, three hours without shelter, and three minutes without air.

Without the Sun's rays, all photosynthesis on Earth would stop. ... While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.

The chemical elements for life might be found within Europa's icy shell, as well as its ocean. Tidal heating could be powering a system that cycles water and nutrients between the moon's rocky interior, ice shell and ocean, creating a watery environment rich with chemistry conducive to life.

While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons. Europa is one of the likeliest places to find life elsewhere in our solar system. There is evidence of a vast ocean just beneath its icy crust, where life could possibly be supported.

1 Answer. On an average, the Sun is about 390 times farther away from the Earth than the moon.

Gun: Yes. The oxidizer is within the gun powder, so a gun will fire in the vacuum of the Moon. The bullet will travel significantly farther, because it will fall slower and there will be no air resistance.

Fortunately, Earth retains heat fairly well, so humans wouldn't freeze instantly. Life would get much more difficult immediately, though. ... Without the Sun's rays, all photosynthesis on Earth would stop. All plants would die and, eventually, all animals that rely on plants for food — including humans — would die, too.

As such, there is simply no way life could survive on the surface of Pluto. Between the extreme cold, low atmospheric pressure, and constant changes in the atmosphere, no known organism could survive. However, that does not rule out the possibility of life being found inside the planet.

Has anyone ever died on the moon? - Quora. No, Nobody has ever died on the moon (yet). In fact, only 12 people ever walked on the moon: they were all American males and that happened between 1969 and 1972 as part of NASA's Apollo program.

Temperatures on the moon are very hot in the daytime, about 100 degrees C. At night, the lunar surface gets very cold, as cold as minus 173 degrees C. This wide variation is because Earth's moon has no atmosphere to hold in heat at night or prevent the surface from getting so hot during the day.
