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.
If you could travel at the speed of light how long would it take you to get to Neptune from the earth?
Neptune is about 2.7 billion miles away from Earth at its closest approach. Since light travels at a speed of about 186,282 miles per second, it would take light about 4 hours to reach Neptune from Earth.
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.
Which outer planet is the bluest?
Neptune is the bluest outer planet in our solar system. Its atmosphere contains methane, which absorbs red light and reflects blue light, giving it a vibrant blue hue.
How far from Earth is Neptune in light-years?
It isn't even 1 light year. Its 243 light minutes.
How long would it take to get to Neptune driving at 75 mph?
Assuming a constant speed of 75 mph, it would take approximately 6,000 years to reach Neptune, which is about 2.7 billion miles away from Earth. This calculation is based on the average distance between Earth and Neptune, the speed of light, and the speed of the vehicle. However, it's important to note that this theoretical calculation does not account for factors such as fuel limitations, the need for rest stops, or the current technology available for space travel.
How many earth days does it take to go from earth to Neptune?
It would take over 16,000 Earth days, or around 44 Earth years, for a spacecraft to travel from Earth to Neptune at its average distance from Earth. The actual time would depend on the speed and trajectory of the spacecraft.
HOW FAST DOES Neptune ROATATE?
At its equator, the rotational speed is 9660 km per hour.
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 long does it take light to travel from earth to Neptune?
Neptune has an average distance from the Sun of 2.8 billion miles and the earth is 0.09 billion miles from the sun so it is 2.71 billion miles from the earth. Light travels at 186,000 miles per second. So 2.71 x 109 divided by 186,000 = 14570 seconds = 4.05 hours = 4.62 x 10-4 years.
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
