The Sun	8 minutes
Jupiter	35 to 52 minutes
Pluto	5 1/2 hours (on average)

How long would it take to get from Earth to Neptune at the speed of light?

At its average distance of 2.76 billion miles (4.4 billion km), light takes 4.1 hours to reach Neptune from Earth.

How long would it take to get to Saturn at the speed of light?

At its average distance of 1.4 billion km, light takes one hour 20 minutes and 15 seconds to reach Saturn from Earth.

How long would it take to get to Neptune at the speed?

Want to go to Neptune? It’ll take 12 years. Fortunately, there’s no good reason anyone would want to go there.

How many years is 1 light year?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

How many years is 500 light years?

The light travels at the speed of 1 light year. Therefore, if we assume light to be travelling, then it will travel 500 light years in 500 years.

How long would it take to get to Alpha Centauri 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, spacecraft will need to travel a substantial fraction of light-speed—10% would get a craft to Alpha Centauri in 44 years.

How long would it take to get to Pluto in the speed of light?

Light itself takes 4.6 hours to travel from the Earth to Pluto.

How long would it take humans to travel 4.2 light years?

Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations.

How long would it take to get out of the Milky Way at the speed of light?

Even if you could travel at the speed of light (300,000 kilometers, or 186,000 miles, per second), it would take you about 25,000 years to reach the middle of the Milky Way.

How long would it take to get to the asteroid belt at the speed of light?

It will take between 26.7 and 35 26.7 and 35 minutes to travel at light speed from Earth to the asteroid belt.

How long would it take to get to Alpha Centauri at the speed of sound?

Alpha Centauri is about 25,000,000,000,000 miles away. Sound at sea level travels about 760 miles per hour (under standard conditions). So it would take sound about 3,750,000 years to get there if standard air extended all the way to the star.

How long would it take to get to Mercury at the speed of light?

At its average distance of 36 million miles, light takes 3.21 minutes to reach Mercury from Earth.

How long would it take to go to Pluto?

So how long does it take to get to Pluto? Roughly 9-12 years. You could probably get there faster, but then you’d get less science done, and it probably wouldn’t be worth the rush. Are you super excited about the New Horizons flyby of Pluto?

How long would it take to get to Mars at the speed of light?

At its farthest point from us, you would reach Mars traveling with the speed of light in just 22.4 minutes / 1,342 seconds. At its average distance away from us, the destination towards Mars at the speed of light would take you only 12.5 minutes / 751 seconds.

How many light-years is the Milky Way?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.

How far back in time can we see in the universe?

We can see light from 13.8 billion years ago, although it is not star light – there were no stars then. The furthest light we can see is the cosmic microwave background (CMB), which is the light left over from the Big Bang, forming at just 380,000 years after our cosmic birth.

How long would it take to travel 1,000 light-years?

To do so, you will need a speed of almost the speed of light, so in the reference frame of Earth, you will have spent just a tad more that 1000 yr to travel 1000 ly. i.e. 1000 years, 4 hours, and 23 minutes in Earth’s reference frame.

How long would it take to get to another universe at the speed of light?

So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.

How long would it take to get to Mars with the speed of light?

At its farthest point from us, you would reach Mars traveling with the speed of light in just 22.4 minutes / 1,342 seconds. At its average distance away from us, the destination towards Mars at the speed of light would take you only 12.5 minutes / 751 seconds.

How long would it take to cross our galaxy at the speed of light?

Even if you could travel at the speed of light (300,000 kilometers, or 186,000 miles, per second), it would take you about 25,000 years to reach the middle of the Milky Way. If we could travel outside our galaxy and look back, this is what our Milky Way Galaxy might look like from above.

How long would it take to get to the nearest habitable planet at the speed of light?

If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!
