How many light years does it takes to go to the moon???
963492
light years are billions of miles long, the moon is only ~250,000 miles from the earth\n\ntry taking how many miles light travels in 1 second 186,000 miles, multiply that by 31,557,600 and you get your answer\n\nhint, there are 365.25 days in a year, that is how we get a leap year every 4 years.\n\ncheers - corey

Compared to the stars the moon moves from west to east.\nIn 27.3 days it returns to it 'start star'.\nIn one night it moves (360 / 27.3) degrees.\nIn one night it moves 13,2 degrees from west to east compared to the stars.

Your gonna need to get the force right.  You need to orbit the earth a few times, then use the gravity to get to the moon.  then, you need to orbit around the moon a few times, then earth, and come down.  Otherwise, you'll become a new addition to our solar systems family!

Normally you'd describe shorter distances like that in AU (astronimical units - 1 AU=distance from earth to sun).\nBut - The distance is almost exactly 499 lightseconds - ie \nearth2sun in lightseconds/(days per year*seconds per day).\n499/(365.25*86400)=0.000016 lightyears.

It averages between 91 and 94 million miles. You can check this by multiplying the speed of light (186,000 miles per second) by the time it takes light to reach the Earth (8 min, 16 sec.)\n\n30 NOV 06, 1711 hrs, GMT.

if we travel at the speed of light, it would take approximately 4.2 years to travel to Proxima Centauri.  Obviuosly, we can't reach that speed.  Space Shuttles can reach a speed of 17,500 mph or 7823.2 m/s.  With this speed, it would take 161059.4 yrs

I know how it will look.  The same side of the moon always faces us because its rotation rate and revolution rate are both the same - 27 to 28 days depending on whether you are looking at it from sidereal or solar time (that's technical lingo you can skip over).  But those two rates are tidally locked and there's no reason that would change.  We'll never see the other side from earth. One thing that WILL change is that is has been, and will continue to, slowly move farther away from us every year.  In the distant future it will appear smaller in the sky and will take a longer time to go around us, 30+ days in the future.  This is because conservation of energy and conservation of angular momentum must both be conserved.  I can explain that, but trust me, you don't want me to.

Distance to the Moon\n\n  \n  \n  \n  \n     \n An Astronomy Tid-Bit about the mean and extreme distances to the Moon\n\n  \n  \n  \n  \n     \n   Note:  Distance is from center to center of orbiting bodies.\n             Kilometers divided by 1.6093 = miles.       \n\n      Many sources, such as beginning astronomy textbooks, yearbooks, and atlases, give the distance to the moon as 384,400 kilometers (km), and  0.055 as the flattening or eccentricity of the moon's elliptical orbit around the Earth.\n\n      The moon travels around Earth in an elliptical orbit, with the Earth at one of the two focuses (foci) of the ellipse.  As a result the distance to the moon varies by quite large amounts.  Its close (or perigee) distance is 384,400 x (1- 0.055) = 363,258 km.  Its far (or apogee) distance is 384,400 x (1+0.055) = 405,542 km.  BUT these values turn out to be the mean or average values.  See the table below for actual distances.\n\n      The actual (computed) distances over 10 centuries, from  1500 to 2500, have been calculated by the Belgian astronomer, Jean Meeus, to be as small as 356,371 km or as large as 406,720 km./1 These values differ from the MEAN values by 6,887 km and 1,178 km respectively\n\n      An excellent and easy-to-use source for the moon's position and distance is "Multiyear Interactive Computer Almanac" produced by the US Naval Observatory, Wash. DC and published by Willman-Bell, Inc., PO box 35025, Richmond, VA  232235.  The program called "MICA15" is on one CDRom for both IBM and MAC systems.  Included with the disk is an information and instruction book.\n\n      I used MICA15 to scan moon distances for the one  year, 2000, shown in TABLE 1.  The same source was used for the ten-year period, 1995 to 2005.  For this ten years,  the smallest distance (356,613.970 km) between Earth and Moon for this period occurred on November 4, 1998.  The largest occurred on March 14, 2002 when the moon was 406,706.975 km away.

this is an answer to a slightly different question (how long does the moon take to make one rotation?): 27 days, 7 hours, and 43.2 minutes.  someone must remember that the moon revolves around the earth (earth-moon center of mass) at the same time that it rotates.

A light year is measured by the time on Earth not by your watch.  However, since one light year is the measurement of the distance that light travels in one Earth year, then one light year always equates to one year on Earth.  So, if you travel one light year, you should be one year older and the Earth would also be one year older (assuming no time anomalies, like a black hole, are encountered during the trip).  Keep in mind that a 'light year' actually measures distance (based on the speed of light).  \n\nHowever, time is always relative to where you are.  So, for you, time progresses at the same rate it always has (for the human body) no matter what's going on around you.  So, if you were gone for 3 minutes (clock time), you'd be three minutes older.  If you were gone for 24 hours, then you'd be 24 hours older.\n\nHowever, if you were to visit the proximity of a black hole, the theory is that time slows down.  So, while your watch may continue at the same rate as it always has (your time has actually slowed down).  So, time on Earth would be progressing at a much faster rate relative to you (even though Earth's progression is normal to them).  So, if you returned to Earth and your watch was only 12 hours later than when you left, time may have progressed days or weeks on Earth.  In which case, your body would have aged 12 hours instead of the days or weeks that it would have progressed if on Earth.

First, a leap year occurs once every 4 years, and is defined as a year in the Gregorian calendar having 366 days, with the extra day, February 29, intercalated to compensate for the quarter-day difference between an ordinary year and the astronomical year. \n\nA light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.\n\nHope this helps. :)

You can see about 4 miles to a flat horizon on the Earth. So from one horizon to the other would be 8 miles. (On the Moon, it would only be 3 miles-- the horizon is only a mile and a half away.)

A light year (or light-year, or lightyear), abbreviated ly, is the distance light travels in one year: about 9.461  × 1015 metres (9.461 petametres), or about 5.879 × 1012 (nearly six trillion) miles. More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely distant from any gravitational or magnetic fields, in one Julian year (365.25 days of 86,400 seconds each). Since the speed of light in a vacuum is exactly 299,792,458 m/s (670,616,629 mph) by the definition of metre, one light year is exactly equal to 9,460,730,472,580,800 m (5,878,625,373,184 mi).\n\nThe light year is often used to measure distances to stars: a light year is not a unit of time. In astronomy, the preferred unit of measurement for such distances is the parsec which is defined as the distance at which an object will generate one arcsecond of parallax when the observing object moved one astronomical unit perpendicular to the line of sight to the observer. This is equal to approximately 3.26 light years. The parsec is preferred because it can be more easily derived from, and inter-compared with, observational data. However, outside scientific circles, the term light year is more widely used by the general public.\n\nA light year is also equal to about 63,241.077 astronomical units (AU). For a list of lengths on the order of one light year.\n\nUnits related to the light year are the light minute and light second, the distance light travels in a vacuum in one minute and one second, respectively. A light minute is equal to 17,987,547,480 m. Since light travels 299,792,458 m in one second, a light second is 299,792,458 m in length.\n\n\nMiscellaneous facts\nIt takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light years). \nThe most distant space probe, Voyager 1, was 13 light hours (only 1.5 × 10-3 light years) away from Earth in September 2004. It took Voyager 27 years to cover that distance. \nThe nearest known star (other than the Sun), Proxima Centauri is 4.22 light years away. \nThe center of our galaxy, the Milky Way, is about 28,000 light years away. The Galaxy is about 100,000 light years across. \nThe Triangulum Galaxy (M33), at a bit under 2.6 million light years away, is the most distant object visible to the naked eye. \nThe nearest large galaxy cluster, the Virgo Cluster, is about 60 million light years away. \nThe particle horizon (observable part) of the universe has a radius of about 46 billion light years, but light from the edge of the observable universe was emitted only 13.7 billion years ago (the age of the universe). The figures differ because distant objects have continued to recede from us due to cosmological expansion. \nOne gigaparsec is equal to approximately 3.26 billion light years.
