How long is a light-year in Earth years?
about 6 trillion miles
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 to travel 1 light years?
about 37,200
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 does it take to reach a light-year?
about 37,200 years
This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.
How far can light travel in one year and why?
A 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.
How far does a light year travel in a day?
The light-year is a 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 ). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days).
How long does it take to travel a light year?
One light-year is 5.87849981 × 10 12 miles. (That’s 5,878,499,810,000 miles, or nearly 6 trillion miles). So, it would take New Horizons 18,449 years to travel one light year.
How many miles equal one light year?
Unit of length that light travels in one Earth year ; equal to just under 10 trillion kilometres (or about 6 trillion miles) The light-year is a unit of length used to express astronomical distances and measures about 9.46 trillion kilometres (9.46 x 10 12 km) or 5.88 trillion miles (5.88 x 10 12 mi).
