What is the speed of light from Pluto to earth?

Answer 1

A rough average of the distance between Earth and Pluto = 3,667,000,000 miles

That's a difficult question to answer precisely. Pluto's average distance from the Sun is 39.4 AU. (An AU is an Astronomical Unit and is defined as the average distance between the center of the Earth and the center of the Sun.) One AU equals 92,955,807 million miles, or about 93 million miles, but Pluto's distance from the Sun ranges from 29.7 to 49.3 AU. So, depending on the orbits of Pluto and Earth, the distance between the two could be anywhere from 28.7 AU (Earth directly between Pluto and Sun when Pluto is closest to the Sun) to 50.3 AU (Earth directly opposite Sun from Pluto when Pluto is farthest from the Sun). However, keep in mind that an AU is an average and that Earth's actual orbit varies anywhere from 91 to 94.5 million miles.

Answer 2

The speed of light is constant at approximately 299,792 kilometers per second in a vacuum. Therefore, the speed of light from Pluto to Earth would also be the same, taking about 4 hours and 25 minutes to travel the distance of around 4.67 billion miles.

Answer 3

Any questions about the time it takes to travel in space from one planet to another needs to address the question of speed and technology. At current technology, it would take decades to travel to Pluto, if it were possible at all.

If the US were to build the Orion Nuclear Pulse Rocket, Pluto would be only a couple of months away. If there were a way to accelerate at one gravity, it would take less than a week to reach Pluto.

Answer 4

Pluto averages 5,913,520,000 km away from the Sun. (Pluto has a highly elliptical orbit; sometimes it's longer, sometimes shorter.) Light travels at 300,000 km per second, so light takes 19712 seconds to get to Pluto. That's 5 hours, 28 1/2 minutes.

Answer 5

The distance to Pluto varies enormously due to it's eccentric and highly inclined orbit. [See related link]

Also, not only does Pluto orbit the Sun but so does the Earth, so the distance between them can vary.

The minimum distance is 4.2 billion km or 0.000443949832 light years.

The maximum distance is 7.5 billion km or 0.000792767558 light years.

For sensible light measurements: Light minutes can be used.

• Min: 233.5 minutes: Just under 4 light hours.
• Max: 417 minutes: Almost 7 light hours.

Pluto varies in distance between 28 and 50 AU or between 0.00044 and 0.00079 light years.

Answer 6

Between about 4 hours and 7 hours, depending on what part of its orbit Pluto is - its orbit is fairly excentric.

Answer 7

As Pluto takes 247.7 years to orbit the sun, and there are 52 weeks in a year it takes 247.7 x 52 weeks or 12,880.4 weeks.

As Pluto takes 247.7 years to orbit the sun, and there are 52 weeks in a year it takes 247.7 x 52 weeks or 12,880.4 weeks.

Answer 8

Mercury, the first planet in our solar system can completely orbit around the sun in a mere 88 Earth Days, but nearly takes 60 days to complete a turn of its axis. Venus, which is the closet planet to Earth, takes 224 days to orbit around the sun. Oddly enough Venus takes longer to complete a rotation of its axis, 243 days, than it does to completely orbit the sun. Mars, one of the closest planets to Earth in size takes around 686.97 days to orbit around the earth and has a nearly identical day of 24.3 hours.

Answer 9

That depends on where the light starts from.

The heat and light from the sun travel a distance from the sun to Pluto that varies over

the course of every 248 years, but averages out to 3.67 billion miles (5.91 billion km).

Answer 10

Pluto's 'year' ... the time it takes to complete one orbital revolution

around the sun ... is 248 earth years.

Since its discovery in 1930, it has completed only about 1/3rd of one 'year'.
