how many human years to travel one light year?

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.

Background: The true length of a year on Earth is 365.2422 days, or about 365.25 days. We keep our calendar in sync with the seasons by having most years 365 days long but making just under 1/4 of all years 366-day "leap" years.

So overall, in about 2 light years/40,000 Earth years, Voyager 1 escapes the pull of our Sun; and, in 4 light years/80,000 Earth years, Voyager 1 will be close to our nearest star. The Voyager Spacecraft travels at about 38,000 mph, which is . 00006 the speed of light.

Its about 3 million light years from Earth; Andromeda Galaxy is about 2.5 million light years away, and the Triangulum Galaxy is 750,000 light years from the Andromeda Galaxy. So, it in answer to your question, light takes about 3 million years to reach us from M33 (Triangulum Galaxy).

It's Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that's 749 million) years. The end of the known universe: 225,000,000,000,000 years (that's 225 trillion) years.

if you go at half light speed your earth twin ages 1.25 years while you age one.

Coe et al. 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).

Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

On the first day of November in 1998, 29-year-old Karl Bushby left Punta Arenas, Chile, to walk around the world. Fifteen years later, he has walked 20,000 of the 36,000 miles needed to complete his epic odyssey.

So 1 light year, aprox 6 trillion miles, is about 418,406 years at constant average speed of 1637mph. @50 we're looking at 20,920,327.02 years. Yikes.... thats around 348 thousand generations of humans created from the original crew (assuming 3 humans per 60 year avg.

1 human year would be about 20-30 gerbil years. You could break that down further, and say that 1 human month is about 2 gerbil years.

Travel Time If Voyager were to travel to the center of our Galaxy, it would take more than 450,000,000 years to travel the 8 kpc. If it could travel at the speed of light, an impossibility due to Special Relativity, it would still take over 26,000 years to arrive!

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

Answer: The calendar year is typically 365 days. However, Earth's orbit around the sun takes slightly longer than this. Because of this difference, every fourth year of our calendar is called a leap year, and has 366 days.

Why is that considered a year? Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. It's not exactly this simple though. An Earth year is actually about 365 days, plus approximately 6 hours.

A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.88 trillion miles (9.5 trillion km).
