Top Five Interesting Facts About Moon

Everyone loves the moon, it is the natural satellite of earth. Moon Night is observed every year on October 12.  The Moon has formed 4.6 billion years ago. Now let us see some amazing facts about the Moon.

Moon The full moon occurs once the moon is on the other facet of Earth from the sun so its face is absolutely lighted by the sun’s lightweight Moon.


1.There are actually four kinds of lunar months

Our months correspond to the length of some time it takes our natural satellite in touch a full cycle of section moon. From excavated tally sticks, researchers have deduced that people from as early as a result of the Paleolithic quantitycounted days in connectedness the moon’s phases. however, there are actually four fully differing types of satellite months. The durations listed here unit averages.

1. Anomalistic – the length of your time it takes the moon to circle the planet, measured from

one periapsis (the highest purpose in its orbit to Earth) to the next: twenty-seven days, 13 hours, 18 minutes, 37.4 seconds.

2. Nodical – the length of your time it takes the moon to tolerate one in all its nodes (where it crosses the plane of the Earth’s orbit) and come back to it: twenty-seven days, 5 hours, 5 minutes, 35.9 seconds.

3. Sidereal – the length of your time it takes the moon to circle the planet, mistreatment the celebrities as a reference point: twenty-seven days, 7 hours, 43 minutes, 11.5 seconds.

4. Synodical – the length of your time it takes the moon to circle the planet, mistreatment the sun because of indicator (that is, the time lapse between 2 serial conjunctions with the sun – going from phase of the moon to new moon): twenty-nine days, 12 hours, 44 minutes, 2.7 seconds. it’s the month that’s the premise of the many calendars nowadays and is employed to divide the year.

2.It would take many thousands of moons to equal the brightness of the sun

The full moon shines with a magnitude of -12.7, however, the sun is fourteen magnitudes brighter, at -26.7. The quantitative relation of a brightness of the sun versus the moon amounts to a distinction of 398,110 to 1. therefore that is what percentage full moons you’d equal the brightness of the sun. however, this all a moot purpose, as a result of there’s no method that you just might work that several full moons within the sky.

The sky is 360 degrees around (including the 0.5 we won’t see, below the horizon), therefore there are over forty-one,200 sq. degrees within the sky. The moon measures solely a 0.5 degree across, which provides it a vicinity of solely zero.2 sq. degrees. therefore you’ll stock up the complete sky, together with the 0.5 that lies below our feet, with 206,264 full moons — and still come back up short by 191,836 within the effort to match the brightness of the sun.

3.There are rules for a way the moon’s craters are named

The satellite craters were shaped by asteroids and comets that collided with the moon. Roughly three hundred,000 craters wider than 1 km (0.6 miles) is assumed to get on the moon’s close to facet alone.

These are named for students, scientists, artists, and explorers. as an example, Copernicus Crater is called for Copernicus, a Polish uranologist United Nations agency completed within the 1500s that the planets move concerning the sun. physicist Crater is called for the Greek scientist physicist, United Nations agency created several mathematical discoveries within the third century B.C.

The custom of applying personal names to the satellite formations began in 1645 with archangel van Langren, the engineer in Bruxelles United Nations agency named the moon’s principal options when kings and nice folks on the planet. On his satellite map, he named the biggest satellite plain (now referred to as Oceanus Procellarum) when his patron, Phillip IV of the European nation.

But simply six years later, Giovanni Battista Riccioli of Bologna completed his own nice satellite map, that removed the names given by Van Langren and instead derived names mainly from those of far-famed astronomers — the premise of the system that continues to the current day. In 1939, the British Astronomical Association issued a catalog of formally named satellite formations, “Who’s United Nations agency on the Moon,” listing the names of all formations adopted by the International Astronomical Union.

Today the IAU continues to make a decision the names of craters on our moon, together with names for all astronomical objects. The IAU organizes the naming of every explicit celestial feature around a selected theme.

The names of craters currently tend to make up 2 teams. Typically, moon craters are named for deceased scientists, scholars, explorers, and artists who’ve become glorious for his or her contributions to their several fields. The craters around the Phoebus Apollo crater and therefore the Mare Moscoviense are to be named when deceased yankeeastronauts and Russian cosmonauts.

4.The encompasses a huge temperature range

If you survey the Internet for temperature data on the moon, you’re going to run into quite a bit of confusion. There’s little consistency even within a given website in which temperature scale is quoted: Celsius, Fahrenheit, even Kelvin.

We have opted to use the figures that are quoted by NASA on its Website: The temperature at the lunar equator ranges from an extremely low minus 280 degrees F (minus 173 degrees C) at night to a very high 260 degrees F (127 degrees C) in the daytime. In some deep craters near the moon’s poles, the temperature is always near minus 400 degrees F (minus 240 degrees C).

During a lunar eclipse, as the moon moves into the Earth’s shadow, the surface temperature can plunge about 500 degrees F (300 degrees C) in less than 90 minutes.

 5.The moon has its own time zone

It is possible to tell time on the moon.  In fact, back in 1970, Helbros Watches asked Kenneth L. Franklin, who for many years was the chief astronomer at New York’s Hayden Planetarium, to design a watch for moonwalkers that measures time in what he called “lunations,” the period it takes the moon to rotate and revolve around the Earth; each lunation is exactly 29.530589 Earth days.

For the moon, Franklin developed a system he called “lunar mean solar time,” or Lunar Time (LT).   He envisioned local lunar time zones similar to the standard time zones of Earth but based on meridians that are 12-degrees wide (analogous to the 15-degree intervals on Earth).  “They will be named unambiguously as ’36-degree East Zone time,’ etc., although ‘Copernican time,’ ‘West Tranquillity time’ and others may be adopted as convenient.”   A lunar hour was defined as a “rumor,” and deciduous, centilunours, and millilunours were also introduced.

Interestingly, one moon watch was sent to the president of the United States at the time, Richard M. Nixon, who sent a thank you note to Franklin. The note and another moon watch were kept in a display case at the Hayden Planetarium for several years.

Quite a few visitors would openly wonder why Nixon was presented with a wristwatch that could be used only on the moon.

Forty years have come and gone without the watch becoming a big seller.


some more facts about the moon

  •   Most of the people think that the Moon is round in shape, but it’s not.  The Moon is shaped like an egg.
  • The Moon’s diameter is 2,160 miles (3,476 km).
  • The Moon’s total surface area is 14,658,000 sq. mi (37,932,000 sq. km).
  • The Moon is approximately 238, 750 miles (384, 400 kilometers) from earth.  The distance changes depending on the position of the Moon, whether it is at its apogee(far away) or perigee(nearby).  At apogee, distance is 363, 295 km and at perigee, it is  405, 503 km.
  • According to scientists, the Moon was formed as a result of a giant impactor giant whack of Earth with mars sized planet, which resulted in the Moon.
  • The Moon’s size varies depends upon its position, whether it is at perigee or apogee.  Generally, the Moon is 14% bigger in its size, when it is at its perigee.
  • The Moon can influence Earth by gravity.  When the Moon is at its perigee, the weather and tides tend to be unstable and create larger tides due to gravitational pull and when the Moon is at its apogee, the weather and tides tend to be more predictable.
  • The Moon’s core is light,  it’s core is 2-4% of its mass, whereas Earth’s core is about 30% of its mass.
  • Temperatures on the moon range from 253° F (123° C) to -387° F (-233° C)
  • The ashes of Dr. Eugene Shoemaker, a man who was declined to be an astronaut due to medical conditions, were flown into a crater on the moon on July 31, 1999, as his dying wish.
  • Any footprints made by astronauts on the moon are still there and will remain for millions of years because the moon has no atmosphere or wind.
