How long would it take to walk to the sun? How long would it take you to walk to the Sun? The Sun is about 150,000,000 km from the Earth. If you can walk 40 km in a day, it would...
How long would it take to travel to Pluto at light speed? Light itself takes 4.6 hours to travel from the Earth to Pluto. How long would it take to get to Pluto in a rocket? Starting from launch on January...
How long will it take to get to Alpha Centauri? Alpha Centauri is 4.4 light-years away, or nearly 40 trillion kilometers. The fastest spacecraft so far launched into space, the NASA-Germany Helios probes, traveled at 250,000 kilometers per hour. At that...
Can we travel at 50 percent the speed of light? The speed of light in a vacuum is an absolute cosmic speed limit. Nothing can go faster than 3.0 x 108 meters per second (that’s 300,000,000 m/s or 1,080,000,000 km/h!). How...
How long would it take to get to Alpha Centauri in light-years? Alpha Centauri is 4.4 light-years away, or nearly 40 trillion kilometers. The fastest spacecraft so far launched into space, the NASA-Germany Helios probes, traveled at 250,000 kilometers per hour....
How long would it take to get to Alpha Centauri traveling at light-speed? At that speed, it would take the probes 18,000 years to reach the nearest star to the sun. To get there in anywhere close to a human lifetime,...
How long would it take to reach the speed of light Andromeda? Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to...
How long would it take to get to Alpha Centauri at current speeds? Alpha Centauri is the nearest star and planetary system to Earth – it is 4.37 light-years away, but it would take a human about 6,000 years to get...
How long would it take to get to Alpha Centauri now? Alpha Centauri is the nearest star and planetary system to Earth – it is 4.37 light-years away, but it would take a human about 6,000 years to get there with...
How close could a human get to the sun? NASA research scientist Eric Christian has said that it might someday be possible to design a vessel that could safely take human astronauts within 4 million miles (6.4 million kilometers) of the...
