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.
The light from our Sun will take about 2.5 million years to reach the Andromeda Galaxy.
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.
When traveling at the speed of light, about 8 minutes. When walking, alot longer.
It takes around 2.5 million years for light from the Sun to reach the Andromeda galaxy, which is approximately 2.537 million light-years away from Earth.

It will take no time at all
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.
0.28 Seconds
About 8 minutes
Light years.
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
2 million days
approximately 3 seconds.
8 minutes
noones quite sure yet about if there is life on other planets because there is just no scientific proof of that yet. It would take to long to trave to other planets outside of our solar system because they can be light years away. However when we develope a way to reach the speed of light im sure we'll find out
It takes about 3,638,768,483 years so it'll take a super long time!
