How long does it take radio signals to reach Triton?

Radio signals travel at the speed of light, which is approximately 299,792 kilometers per second (about 186,282 miles per second). Triton, Neptune's largest moon, is about 4.3 billion kilometers (2.7 billion miles) from Earth on average. Therefore, it takes radio signals roughly 4.3 hours to reach Triton from Earth, depending on the relative positions of the two bodies in their orbits.

How do very long radio waves reach stations beyond the curvature of the Earth?

Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.
