The time that it takes light to reach Earth from the other planets is a function of where each planet is in its orbit. Light travels at 186,000 miles per second (300,000 km/sec), and each of the planets is moving in its own orbit.
For example, Venus almost directly between the Sun and Earth this month, so Venus is only about 40 million miles away, about 3 light-minutes.
Jupiter, on the other hand, is across the Sun from Earth, so it is over 500,000 miles away. (My Stellarium computer program tells me that Jupiter is 5.7 AU away right... NOW.) So that's 2850 seconds or 47.5 light-minutes away.
Neptune and Uranus are also at the other ends of their orbits, so they are even FURTHER away.
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
8 min.
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
Once the light reaches the surface of the Sun, it takes approximately 8 minutes and 20 seconds to reach Earth. This can be calculated by dividing the distance to the Sun by the speed of light: 150,000,000 km / (300,000 km/second).
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.

It takes approximately 8 minutes for the Sun's light to reach Earth.
35 minutes. Obviously it depends where the planets are in their orbits. I think that 35 minutes is about the least possible time.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
About 37 years.
By using the parallax you can deduce the distance to all planets and many stars. [See related link]From that, simple math can calculate and distance to light speed.
