Our Sun is at a distance of 8 light-minutes. The next star outside our Solar System is Proxima Centauri, at a distance of 4.2 light-years.
It takes about 500 seconds or 8 1/3 minutes for a ray of light to travel from the nearest star to the earth and that star is called the sun.
Actually the nearest star (except for the sun) is Proxima Centauri is next at 4.3 light-years from the Earth. It would take 3.4 years at one light-year/year for radio waves to reach Earth from there. This is because the radio waves are travelling in a vacuum and all electromagnetic wave in a vacuum travel at "C" AKA the speed of light.
A "light year" is a measure of distance, derived from "how far light can travel in one Earth year". Thus, if you shine a torch for the amount of time it takes the Earth to orbit the sun exactly once, that light would have travelled the distance of a "light year".
Light travels at the speed of 186,000 miles per second. A light year is the distance light travels in one year. It takes 8 minutes for light to travel from the sun to the earth.
The nearest neutron star to us is called an unremarkable PSR J0108-1431. It is located about 424 light years from us in the constellation Cetus.
Because space does not stop light from traveling. The earth has light sources on it that help it be seen on the dark side and on the light side it reflects a massive amount of light from the sun. The moon reflects light from the sun. The majority of what astronauts see locally is a reflection of the suns energy.

The nearest star to us is the SUN. It takes light about 8 minutes to travel from the Sun to Eart. #The next nearest star is Alpha Centurii. Light takes about 4.5 years to travel from this star to Earth.
Waves of heat and light, called radiation, travel to earth.
This varies widely, between about four light-years for the nearest star (after the Sun, that is), to billions of light-years for stars in the farthest observable galaxies.
It takes approximatly 7minutes to travel from sun to earth the sun light.
The nearest star to Earth is the sun, at a distance of 0.000016 light years from Earth. The next nearest star, Proxima Centauri, is about 4.2 light years away.
The nearest star to Earth is regarded as the Sun. The light from the Sun takes 8.3 minutes approximately, after calculating the distance of the Sun from Earth and the speed of light. It can be calculated by the formula: Time = Distance / Speed. If you mean the nearest star apart from the Sun, that is "Proxima Centauri". That light from that star takes about 4.22 years to reach us.
Light waves travel from sun to the earth.
Waves of heat and light, called radiation, travel to earth.
light can travel around earth about seven times
As light, of course.
Light take approximately 8 minute 20 seconds to travel from the sun to the earth.
