# How long would it take to get to mercury from earth at the speed of light?

The Speed of light is approximately : 186000 miles per second The distance from the Earth to Mercury is approximately 48 million miles on average. so, 48000000 / 186000 = 258 seconds 60 seconds per minute so 258 / 60 = 4.3 minutes

### How many light years does it take to reach Mercury from Earth?

Light years are a measure of distance not time. However they can be used to gauge how long it would take you to get there if you travelled at the speed of light. Mercury is approximately 4 light minutes away from earth (46.5 million miles) so it would take a beam of light around 4 minutes to get to Mercury (assuming Mercury is at its closest point to the Earth)

### What is the speed of light energy?

the speed of light is 300,000 kilometers per second. and if you ask about how far the sun is from earth that would be 150,000,000 kilometers so in calculation that would mean it would take just about 8 minutes and 17 seconds for the suns light and heat to travel to the earth. now imagine the earth without the o-zone layer we would be fried like mercury. ☺

### How long would it take to travel from earth to mercury traveling at 40000 miles per hour and at the speed of light?

When Mercury is on the opposite side of the sun from us, it would take a bit longer. Assuming we're both on the same side, it would take light between four and five minutes to reach from Earth to Mercury. Something traveling 40,000 miles per hour would require 1250 hours, or 52 days. Pretty close to two months.

### How long would it take to get to mercury if traveling at a speed of 100000 km per hr?

That would depend on where Earth and Mercury were on their particular orbits of the Sun. Assuming they were at their closest conjunction as Mercury is 57.91 million km from the Sun and Earth is 149.6 million km from the Sun, the distance between them will be 91.69 km. So at a speed of 1 million km/hour it would take you 91.69 hours to reach Mercury From Earth.

### If you were traveling at the speed of light how long would it take you to get from the sun to Earth?

### When a body of some mass travels with a speed of light and hits the earth then what happens to the earth?

The mass of a body increases as its speed increases. A body that has any mass when it's not traveling at the speed of light would have infinite mass when it is traveling at that speed. So its kinetic energy would be infinite, and anything it hit ... whether a bird, a plane, the Earth, or a star ... would be totally blasted to smithereens that were too small to detect. Fortunately, a body that…

### How fast would you have to travel in order to reach a star that is 50 light years away from Earth when you are 40 years older than you were when you left earth?

You would have to be travelling faster than the speed of light in order to do this. And, theoretically speaking, this would be impossible to do. However, if you were possible to travel faster than the speed of light, you would need to be travelling 1.25x the speed of light (which is about 3.75 x 108 m/s2).

### How many days does it take to get to mercury to earth?

Let's assume you are going to travel from Mercury to Earth when they are the closest at only 48 million miles. If you walking, at a clip of 4 mph, it would take you 12 million hours, or 500,000 days, or 1,369 years and 10 months. If you were traveling at the speed of light, it would take you about 4 minutes. If you took the Space Shuttle, it would take about 117 days. Are…

### If you were able to travel at the speed of light how long would it take you to reach Rigel?

If I were able to travel at the speed of light, I would arrive at Rigel instantaneously, from my point of view. It would seem longer to you as an observer on earth. Rigel is estimated to be between 700 and 900 light years from earth, so between 700 and 900 years would elapse on earth before my instantaneous arrive there.

### Light takes time to reach earth but according to Einstein it should not right?

No; according to Einstein it should take time for light to reach earth from the sun. Light is not instantaneous. The trip takes about 8 minutes. You may be confusing this with the theoretical result that if you were able to accelerate to the speed of light (you cannot) then for you, time would stop passing. You'd still be traveling at light speed, but you would have no experience of the passage of time. If…

### How can you go with the speed of light?

A person cannot travel the speed of light because a propellant to move a space ship in the vacuum of space would have to travel faster than light speed. Since everything is relative, nothing travels faster than light speed (speed C). If light, for example, was to power a space ship by pushing on giant panels it would still not be able to push the space ship fast enough to travel at light speed. If…

### How long would it take to go to Venus from Mercury travelling at the speed of light?

Assuming that the distance from Mercury at its perihelion is approximately 44 million kilometers, the time to travel would be 146.768 Light seconds, 2.446 Light minutes, or .0041 Light hours. Assuming that at its aphelion Venus to Mercury is 174 Million kilometers the distance to travel would be 580.402 Light Seconds, 9.673 Light minutes or .161 Light hours. The mean distance is 58 million kilometers, travel time will be 310.818 light seconds, 5.18 light minutes…

### If earth and a star were diverging at a combined speed greater than that of light would that star not appear as a black hole?

No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.
