If you could travel at the speed of light how long would it take you to get to Neptune from the earth?
The time would be T= d/c where d is the distance between Earth and Neptune and c is the speed of light.
How many light years does it take to get from earth to neptune?
At the speed of light it takes 4 hours 11 minutes and 27 seconds.
How long would it take to travel from Neptune in light years?
The average distance from the Sun to Uranus is 2.88 billion km. The distance from the Earth to Uranus would vary depending upon if our planet is on the near side of the Sun from Uranus or the far side. If we take the average distance of the Sun to Uranus as a neutral point, and the speed of light is 300,000 km/sec --- (2.88 billion km) / (300,000 km/sec) = 9600 light sec, or about 160 light min, much, much less than a light year. In other words, traveling at the speed of light, it would only take about 2 1/2 hrs to get to Uranus. Light years are a term usually reserved for great distances, such as the distance between stars.
HOW FAST DOES Neptune ROATATE?
Neptune rotates on its axis at a speed of about 16 hours and 6 minutes, resulting in a relatively slow rotation compared to Earth's 24-hour day. This means that Neptune has a longer day than Earth.
Has light originating outside of earth been tested for speed?
Light from stellar sources will travel at the same speed as light generated on earth.
How far from Earth is Neptune in light-years?
It isn't even 1 light year. Its 243 light minutes.
What is Earth's speed of light?
Nothing to do with earth - speed of light does not matter where it is - and is just over 186,000 miles per second.
How fast would it take to travel to Neptune at light speed?
it would take about 12 weeks
Could you see with the little sunlight on neptune?
Yes. The sunlight on Neptune is less than that on Earth, but brighter than the light of a full moon.
What unit would you use to describe the distance between the Earth and Neptune?
Light years
Why is the distace between earth and the sun measured in light minutes and the distance between neptune and the sun measured in light hours?
Because it only takes 8 minutes for sunlight to reach Earth, but it takes 4 hours to reach Neptune.
Why is Neptune brighter than Pluto when seen from the earth?
Because it is closer to the Earth and it is larger, so it reflects more light.
