I happen to know that the speed of light c = 186,000 miles per SECOND. if we divide 240,000 miles by 186,000 miles per second, we get the answer approx
1.3 seconds
.
How far away is 1 Lightyear in 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 fast does light travel per miles?
Stationary Light
Light from a stationary source travels at 300,000 km/sec (
186,000 miles/sec
).
How long does it take for light to travel 186000 miles?
Light-year is the distance light travels in
one year
. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
How far can light go in 1 hour?
Light travels at about 300,000 km in one second. 1 hour has 60 minutes and one minute has 60 seconds, so light will travel about 60 * 60 * 300, 000 = 1080000000 km in an hour. 1 light hour =
675000000 miles
.
How far will light travel in 24 hours?

How many Earth years is a Lightyear?
A light-year is the distance light travels in
one Earth year
. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.
How long would it take a human to travel one light-year?
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.
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.
Why is light the fastest?
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).
Only massless particles, including photons, which make up light, can travel at that speed
. It’s impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
Is the speed of light fast?
Light travels at a constant, finite speed of
186,000 mi/sec
. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second.
What travels faster light?
What is a tachyon? Tachyons are one of the most interesting elements arising from Einstein’s theory of special relativity. The 1905 theory is based on two postulates,
nothing with mass moves faster than the speed of light
(c), and physical laws remain the same in all non-inertial reference frames.
How long would it take to travel 100 light years?
Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in
62 years
.
How long does it take to travel 2.5 million light years?
For example, the Milky Way galaxy is some 100,000 light-years across, and our closest galactic neighbor, Andromeda, is some 2.5 million light-years away. In other words, it takes light
2.5 million years
just to travel from our galaxy to the one that is right next to us.
How long will it take to travel a light minute?
How far do you think light travels in a minute? To figure this out,
multiply the distance that light travels in a second by 60
because there are 60 seconds in a minute. So light can travel 18,000,000 kilometers in one minute!
How fast does light travel in a vacuum per second?
The speed of light traveling through a vacuum is exactly
299,792,458 meters (983,571,056 feet) per second
. That’s about 186,282 miles per second — a universal constant known in equations as “c,” or light speed.
How long is a light minute in seconds?
A light minute equals
60 light seconds
. The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics.
How many kilometers can you travel an hour?
Kilometers per hour is often used for car speeds. One hour at this speed moves you
100 km
. Example: One minute at 60 km/h moves you 1 km.
How far away is one light day?
| Unit Definition Distance | light-day 24 light-hours = 86400 light-seconds 2.590206837×10 13 m | light-week 7 light-days = 604800 light-seconds 1.813144786×10 14 m | light-year 365.25 light-days = 31557600 light-seconds 9.460730473×10 15 m |

How long would it take to drive around Earth’s equator?
In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer. It would take you almost
17 days driving at 100 km/hour
, 24 hours a day to complete that journey. If you like, you can calculate the Earth’s circumference yourself.
What is a light hour?
Definition of light-hour
:
a unit of length in astronomy that is equal to the distance that light travels in one hour in a vacuum or about 1.1 billion kilometers
.
How long would it take to get to the Sun?
It would be faster to fly to the sun: It would take
169,090 hours
to fly there at 550 miles per hour. It would take 7,045 days to fly there at 550 miles per hour. It would take 19.3 years to fly there.
How long would it take us to get to Jupiter?
The distance between Earth and Jupiter depends on the orbits of each planet but can reach more than 600 million miles. Depending on what the missions do and where they go, it can take around
two years to six years
to reach Jupiter.
How many light years can we see?
We can see objects up to
46.1 billion light-years
away precisely because of the expanding universe. No matter how much time passes, there will forever be limits on the objects we can observe and the objects that we can potentially reach.
How long would it take to travel to Pluto?
Starting from launch on January 19, 2006, and with a gravity assist from Jupiter along the way, NASA’s New Horizons spacecraft took
9 years and 5 months
to get to Pluto, 39 AU from the Sun. It traveled at an average speed of 4.1 AU/year. Deep-space missions can take up to 10 years from development to launch.
How long would it take to travel to Mars?
According to NASA,
a one-way trip to Mars would take about nine months
. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.
How far could a human travel in space?
The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were
400,171 kilometers (248,655 miles)
away from Earth on April 14, 1970. This record has stood untouched for over 50 years!
