At its closest, Pluto is about 4.4 billion km (2.7 billion miles) from the Sun. Light travels at about 300,000 km/sec, so it takes about 15,000 seconds, or about 4.2 hr, for light to travel from the Sun to Pluto. At its most distant, Pluto is about 7.4 billion km away, so light takes about 6.8 hr to reach it from the Sun.

How long ago has Earth been broadcasting radio signals into outer space?
Earth has been broadcasting radio signals into outer space since the late 1800's.
How do you work out how long radio waves take to get from Earth to Pluto?
You can calculate the time it takes for radio waves to reach Pluto by dividing the distance between Earth and Pluto by the speed of light, which is approximately 299,792 kilometers per second. Pluto is about 4.67 billion miles away from Earth on average, so it takes about 4.67 hours for radio waves to travel from Earth to Pluto.
How long would it take a rocket to travel from Pluto to the sun?
On January 19, 2006 a space probe was launched and sent to Pluto. It was expected to reach Pluto in 2015. So it would take about 9 years to get to Pluto.
How long does it take Pluto's moon to go around Pluto?
Pluto's largest moon is called Charon and it takes 6.39 days to travel around Pluto! It is also the largest moon in comparison to its "parent" planet in the solar system! (about half the size of Pluto)
What type of electromagnetic signals are currently used to communicate through space?
Radio waves are the most commonly used electromagnetic signals for communication through space. These waves have long wavelengths that can travel long distances without getting absorbed by the Earth's atmosphere. Additionally, microwaves and infrared signals are also used for specific space communication purposes.
Does AM radio travel through the ionosphere?
Yes, AM radio waves can travel through the ionosphere due to their long wavelength. They bounce off the ionosphere and can be reflected back down to Earth, allowing AM radio signals to travel long distances.
What layer of the atmosphere is important for long distance radio signals?
The ionosphere, specifically the F layer, is important for long distance radio signals because it reflects the signals back to Earth allowing them to travel long distances by bouncing off the ionized layers.
What does AM and FM on the radio stand for?
Amplitude Modulation and Frequency Modulation. They are different methods of transmitting radio signals. AM is good for transmitting radio signals long distance FM is good for transmitting radio signals short distances but better quality
Which travel long distances am or FM?
AM radio signals normally go further especially on long-wave broadcasts which can cover a radius of 300-400 miles. FM signals use shorter waves (around 1 metre long) and the range is usually 30-40 miles.
What is the name of the electromagnetic wave use to send signals in satellites?
The electromagnetic wave used to send signals in satellites is called radio waves. These waves have long wavelengths and are able to travel long distances through space without the need for a physical medium.
What is an Atmospheric bounce?
An atmospheric bounce is a phenomenon that occurs when certain radio frequencies, such as VHF and UHF signals, are refracted by the Earth's atmosphere. This can allow radio signals to travel much farther than expected by bouncing off the ionosphere, which can create long-distance communication links over the horizon.
How do long radio signals get back down to earth?
How do THEY get back to earth?!
How are radio waves used for effective communication around the world?
Radio waves are used for effective communication around the world by transmitting information through radio frequency signals. These signals can travel long distances and penetrate obstacles, allowing for widespread communication. Radio technology relies on modulation techniques to encode information onto the radio waves, enabling communication between devices such as radios, cell phones, and satellites.
What is a wireless transmission medium that distributes radio signals through the air over long distances?
Broadcast Radio
