How long would it take to get to Sirius?
Astonishingly, even travelling at around 40,000mph it will take 296,000 years to reach Sirius. Most experts believe mankind will have long since become extinct, or will have evolved into an entirely different species by that time.
How long would it take a rocket to travel a light year?
One light-year is 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 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 5 light years?
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 far is Sirius from the earth?
8.611 light years
Sirius/Distance to Earth
How long would it take the voyagers to reach Alpha Centauri?
Neither Voyagers is aimed toward Alpha Centauri, but if one of them were – assuming it maintained its current rate of speed – it would requires take tens of thousands of years to this next-nearest star. Eventually, the Voyagers will pass other stars.
How far away is the brightest star in the sky?
In some 296,000 years, Voyager 2 will pass 4.3 light-years from Sirius, the brightest star in the sky. Hmm, 4.3 light-years. That’s the distance between us and Alpha Centauri. What about the New Horizons spacecraft, the first spacecraft ever to visit Pluto and its moons.
How fast does the New Horizons spacecraft travel?
What about the New Horizons spacecraft, the first spacecraft ever to visit Pluto and its moons. NASA’s New Horizons spacecraft travels at 36,373 miles per hour (58,536 km/h). Launched from Earth in mid-January, 2006, it reached Pluto in mid-July, 2015 … nine-and-a-half years later.
Could a spacecraft with a warp drive get to Alpha Centauri?
If New Horizons were aimed toward the Alpha Centauri system, which it isn’t, it would take this spacecraft about 78,000 years to get there. So conventional rockets won’t work because they are too slow. What a spaceship with warp drive might look like. Credit: Mark Rademaker/Mike Okuda/Harold White/NASA.
