How many miles is 1 light year
How far away is 1 Lightyear in miles?
5,878,625,370,000 miles
The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km). At first glance, this may seem like an extreme distance, but the enormous scale of the universe dwarfs this length.
How long would it take to travel 1 light-years?
about 37,200 human years
Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.
What is 1 light-year away?
about 6 trillion miles
For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).
How far is a light-year in years?
A light-year, alternatively spelled lightyear, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×1012 km), or 5.88 trillion miles (5.88×1012 mi).

Is warp drive faster than light?
A warp drive is a device that distorts the shape of the space-time continuum. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude.
How long would it take to travel to Pluto?
The asteroid belt is nothing but tourist traps and the rest stops really thin out after Saturn,” Frank writes, so he also gives up the calculation were we to fly by Boeing 777. With a maximum velocity of 590 miles per hour, the trip to Pluto will only take about 680 years.
How long is 1 second in space?
It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).

How long would it take to travel 4 light years?
Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
How many light years across is the universe?
94 Billion Light Years
Size: 94 Billion Light Years. The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across.
Do people age in space?
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
How is 1 hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
How long is a year in Mars?
Since Mars is further from the Sun compared to the Earth, a Martian year is longer: 687 days. That’s just less than two Earth years. Although you wouldn’t age any quicker, living on Mars you’d only be celebrating a birthday roughly every two years, since a birthday is marking another orbit around the Sun.
How long is 1 year on the moon?
Since each lunation is approximately 291⁄2 days, it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since the period of 12 such lunations, a lunar year, is 354 days, 8 hours, 48 minutes, 34 seconds (354.36707 days), purely lunar calendars are 11 to 12 days shorter than the solar year.
How cold is it in space?
about minus 455 degrees Fahrenheit
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
Do you age in coma?
the cellular mechanism for ageing has been associated with progressive shortening of telomere length on the ends of each chromosome with each cell cycle.. in the contect of this, a coma wouldnt necessarily keep you young, but you would age just the same.
What happens every 33 years?
The lunar-moon cycle, when the sun and moon align, repeats every 33 years.
How long is a day on Pluto?
6.4 Earth days
Pluto’s day is 6.4 Earth days long.

What happens every 28 years?
The solar cycle is a 28-year cycle of the Julian calendar, and 400-year cycle of the Gregorian calendar with respect to the week. It occurs because leap years occur every 4 years and there are 7 possible days to start a leap year, making a 28-year sequence.
Why can’t humans live on moon?
Although you might think it would be cool, humans could not live on the moon! (Maybe one day in the future…) The moon has almost no atmosphere, so there’s no air for us to breathe. There is no water on the moon either, and we need to drink water to survive.
What is the difference between a solar year and a lunar year?
A solar year — the time it takes Earth to orbit the sun — lasts around 365 days, while a lunar year, or 12 full cycles of the Moon, is roughly 354 days. Because of this discrepancy, a purely lunar calendar — like the Islamic, or Hijri, calendar — doesn’t stay aligned with the seasons.
What does it mean to have Saturn in your 5th house?
Saturn in the Fifth gives you a longing to be that life of the party when in your most defensive moments, you’re the killjoy. You yearn to be admired and loved for who you are, but struggle to know your true worth. Creativity is a biggy with the Fifth House.
