Light travels at 300,000 km/sec or 3*10^8 m/s. Thus 1 light second= 3*10^8 m 1 light minute=1.8*10^10 m, or 18 billion meters, (18 gigameters), 18 million km, 11.1 million miles The Sun is 8.4 light minutes from earth. 1 light hour= 1.08*10^12 m, 1.08 trillion meters, (1.08 terameters) 1.08 billion kilometers, 667 million miles 1 light day=2.59*10^13 m, 25.9 terameters, 25.9 billion km, 16 billion miles 1 light year= 9.47*10^15 m, 9.46 petameters, 9,460 terameters, 9.46 trillion km, 5.84 trillion miles. The nearest star is Alpha Proximi, 4 light years away or 23.4 trillion miles from earth. If you could drive there at 60 mph it would take 4.45*10^7 years, 44.5 million years The fastest humans were the Apollo astronaughts, who reached 25,000 mph, it would take them 106,849 years to get Alpha Proximi. 1 parsec is 3.27 light years, =3.1*10^16 m, 31 petameters, 310 trillion km, 191.35 trillion miles. The nearest possible earth like planet, Gliese 581 C, is 20.5 light years, or 6.3 parsecs away. Useing today's conventional chemical rockets, (25,000 mph) it would take 547,198 years to get there. Using fusion rockets that can achieve speeds of .5c (50% the speed of light) it would take 41 years as viewed from earth, (at such relativstic speeds time would slow down for anyone inside the rocket, so it would seem as if 35.5 years had passed). At .75c the trip to Gliese 581 C would take 27.3 years as seen from earth, 18.1 years elapsed inside the rocket. At .9c (the realistic limit for even the most advanced antimatter powered space ships due to the exponentially larger energy requirements needed to speed up as you approach the speed of light) the trip would take 22.8 years as seen from earth, for those inside the ship 9.9 years would have passed. Thus it is clear that only 4 possibilities exist for humans reaching other earth like planets, (10 years away is the closest possible earth like planet, most others will be centuries or millenia away) 1. Discover how to travel faster than light by warping space, theoretically possible but the energy requirements are too great for this to be practical, most likely faster than light travel is impossible. 2. Advance medicine to the point where we can slow or stop aging and give humans life spans measured in centuries of millenia. 3. Develop a way to put humans in suspended animation. 4. Build generational ships where several generations of people are born, work and die, while in transit. Also note that due to time dilation effects, (time slows down as you travel at higher velocities) at .9c velocity for each 1 year that passes on the ship 2.33 years passes on earth. So interstellar empires are impossible, since it would take decades or centuries to communicate with other planets, and even visiting earth from Gliese would mean arriving decades into the future, from the perspective of someone onboard a ship coming to earth. Thus any colonists leaving earth would almost certainly be making a 1 way trip.
366 light days, if you interpret leap year to be the entire year in which there is a February 29.
A gibbon can typically jump up to 8 meters in distance in a single leap.
Given 366 days in 1996 (leap year) 24 hours in a day, 60 min in an hour, 60 seconds in a min speed of light = 300,000 km per second ((366 * 24 * 60 * 60) - 1) * 300000000 = 9.4867197e15
They are very different. Years are divisible by 4 are leap years, though if they are divisible by 100 and are not divisible by 400, then they are not leap years. A light year is a measurement of distance, not time. It is the distance that light travels in a year. It is about six trillion miles or nine trillion kilometres.
A light-year is a unit of distance, not a unit of time.
Both contain the word "year," but are otherwise unrelated. A light year is a unit of distance, while a leap year is a correction to a unit of time.
The question should be How Long is a light year (in standard form) as a light year is the DISTANCE that light will travel in one year No...I'm not sure what a light year would be in a leap year.
The red kangaroo leap over nine meters far and three meters high. The eastern grey can jump up to nine meters in one bound. The western grey, the Wallabies and other smaller macropods are all much smaller in size.
the answer is 9.9 m/s
A light year is the distance which light will travel in a vacuum. Light travels at 299,792,458 m/s in a vacuum, one year is 31557600s (on average taking into account leap years) so 1 light year is 9.46073x10^15m or 9 460 730 473 000 km
Behavior: Adult bullfrogs can generally leap about 1 meter (3 feet), but they are able to jump a distance of 2 meters (6 feet) without difficulty. Males produce loud calls to attract females and establish their territories.
Please note that a light-year is a unit of length, not a unit of time. It is the distance light travels in a year. An average value for the year is used for this purpose; thus, no distinction is made between normal and leap years. The average value, in the official definition of the light-year, is a so-called Julian year; from the Wikipedia: "In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of 86,400 SI seconds each."
