The speed of light Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes.

If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour.

Yes the trick isn't to actually travel faster than light, just use a shorter way. There is a theoretical model of a drive which could warp and bend space to travel faster than light.

Brandon from Orlando: How long does it take to get the shuttle into space? It takes the shuttle approximately 8-1/2 minutes to get to orbit. And if you think about it, we're accelerating a 4-1/2 million pound system from zero miles per hour to its orbital velocity of 17,500 miles per hour in those 8-1/2 minutes.

The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target. It really just depends on how much fuel you're willing to burn to get there. More fuel, shorter travel time.

How long would it take to get to the Andromeda Galaxy? Forget it! 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 get there if (and it's a huge 'if') we could travel at the speed of light.

The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.

At their closest, Earth and Mars are 225 million kilometers apart, which is equal to 12.5 light minutes, making the journey from Earth to Mars, if a straight line course was possible, twelve and a half minutes at Warp 1.

at 3,000 light years, or 9.46 trillion kilometers x 3,000, and flying at 59,000 mph, it would take 481 billion years to reach the black hole.

At the rate of 17.3 km/sec (the rate Voyager is traveling away from the Sun), it would take around 225,000,000,000,000 years to reach this distance. At the speed of light, it would take 13 billion years!

2 Answers By Expert Tutors Since the speed of light is given in m/s, the distance must first to converted from km to m. so 615.38s = 615.38s x (1 minute / 60s) = 615.38 / 60 minutes = 10.26 minutes = time in minutes that it takes the light from the sun to arrive at Venus.

1G thrust is equal to 1 gravity of constant acceleration, and it would get you to Mars in about 1 day and 7 hours time.

The speed of light is torturously slow, and these 3 simple animations by a scientist at NASA prove it. The speed of light in a vacuum is about 186,282 miles per second (299,792 kilometers per second).

Sun is about 8.3 light minutes from the Earth. This means it would take 8.3 minutes for light to reach from the Surface of the Sun to reach the Earth. If you are traveling in a Jumbo Jet , it would take you about 19 years to reach the Sun.

All in all, your trip to Mars would take about 21 months: 9 months to get there, 3 months there, and 9 months to get back.
