How far exactly is 1 light-year?

How long would it take to travel 1 light years?

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.

What distance is 1 light-year closest to?

approximately 6 trillion miles A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers is cumbersome given the exceedingly large numbers being discussed.

Does 1 light-year equal 1 year?

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)….Definitions.

1 light-year= 9460730472580800 metres (exactly)
≈ 9.461 petametres
≈ 9.461 trillion kilometres (5.879 trillion miles)
≈ 63241.077 astronomical units

Is warp speed possible?

None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.

How long would it take to travel to Pluto?

New Horizons launched on January 19, 2006, and it'll reach Pluto on July 14, 2015. Do a little math and you'll find that it has taken 9 years, 5 months and 25 days. The Voyager spacecraft did the distance between Earth and Pluto in about 12.5 years, although, neither spacecraft actually flew past Pluto.

Who created universe?

Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.

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.

How many stars are within 10 light years of Earth?

As of October 2012, astronomers have been able to detect planets in the Solar System and around Alpha Centauri B and Lalande 21185 among the nearest 12 stars….Stars within 10 light-years.
