How much Earth time is a light-year?

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.

What is 30 light years away?

List of star systems within 30–35 light-years

What is 20 light years away from Earth?

Researchers detected the planet orbiting one of Earth’s nearest stars, a cool red dwarf called Gliese 581, 20 light years away in the constellation of Libra. Measurements of the planet’s celestial path suggest it is 1½ times the size of our home planet, and orbits close to its sun, with a year of just 13 days.

What star is 32 light years from Earth?

AU Microscopii
The breakthrough, announced today in Nature, was made possible in part by NASA’s TESS and Spitzer space telescopes. Located about 32 lightyears from Earth, AU Microscopii, or AU Mic, is a young star between 20 and 30 million years old, which is about 180 times younger than our own Sun.

How long would it take to travel 25 000 light-years?

The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light.

How many light years are in 30 years?

Light years are not a time, it is a distance. 30 light-years is the distance that light travels in 30 years. If you imagine light travels about 186,000 miles in one second multiply that by the number of seconds in 30 years then you have the distance – it’s a very long way.

What is the difference between an Earth year and a light year?

An earth year is a unit of time. A light year is a measure of distance. Explanation: A light year is the distance light will travel in a vacuum over the period of one (earth) year. Since light travels at about #186,300# miles per second, with #86,400# seconds per day and about #365# days per year, that works out at about:

How far does light travel in a year?

So how far does light go in a year? Light travels a whopping 9,460,528,000,000 km in a year, equivalent to 5,878,499,562,555 miles. Those are really large numbers! How far is 40 light-years? In February 2017, astronomers detected seven Earth-sized planets orbiting a single star 40 light-years away from Earth.

What is the conversion of light years to kilometers?
