How long does it take a pulse of laser light to reach Mars and back if they both are at their closest approach?
It takes around 7 minutes for light to travel from Earth to Mars when they are at their closest approach, known as opposition. Therefore, for a pulse of laser light to reach Mars and return to Earth, it would take approximately 14 minutes.
What takes longer to reach earth light from the sun or light from other stars?
Light from the sun because all light travels at the same speed, and the sun is the closest star to the earth, so therefore the light from the sun reaches the earth before light from other (further away) stars
How lond does it take light to reach Earth from Mars?
It takes light about 3 minutes to travel from Mars to Earth when the two planets are at their closest distance, which is about 54.6 million kilometers. At their farthest distance, which is about 401 million kilometers, it takes light about 22 minutes to reach Earth from Mars.
How long does it take starlight to reach us?
The distance of Altair is listed as 16.8 light-years.That's something like 1.1 million times the distance from the earth to the sun !
How long does it take for the light generated by the star Betelgeuse to reach Earth?
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.

How long to closest star?
The nearest star is the Sun; it takes light 8 minutes and 20 seconds to reach Earth from the Sun. The closest star outside our Sun is Proxima Centauri; it takes light 4.2 years to reach us. At speeds slower than the speed of light, it will obviously take longer.
What takes longer to reach earth light from the sun or light from other stars?
Light from the sun because all light travels at the same speed, and the sun is the closest star to the earth, so therefore the light from the sun reaches the earth before light from other (further away) stars
How does it take for light to reach earth?
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
Does most of suns energy reach earth in light energy?
it does reach the earth in light energy.
How much time needs to reach the earth explosions on earth?
At its closest point, sunlight only takes 490 seconds to reach Earth.
How does sunlight reach earth?
the light speed are very fast so light easily reach on earth
How long does it take reflected light from Jupiter to reach the earth?
Jupiter and Earth are not always the same distance apart. At their closest, it would take about 1.96 seconds. At their furthest, about 3.22 seconds.
How lond does it take light to reach Earth from Mars?
It takes light about 3 minutes to travel from Mars to Earth when the two planets are at their closest distance, which is about 54.6 million kilometers. At their farthest distance, which is about 401 million kilometers, it takes light about 22 minutes to reach Earth from Mars.
Do constellations have a fixed shape?
because stars cannot move fast enough for people to be able to tell that they moved from Earth, and also because it takes thousands of years for the light of stars to reach Earth. If the big bang happened at one particular moment, it would take eight minutes for the first light to reach earth (the sun is the closest star to the earth, and it is eight light minutes away)
During which season does the Earth reach periphelion?
Winter. In the beginning of January, the Earth is closest to the sun.
How long would it take you to reach the nearest star from Earth?
How long will depend on the velocity. The closest star would be 4.24 light years away
