The star won't normally "travel the 37 light-years to Earth". 37 light-years would most likely be the distance from the star to Earth; it takes light from the star 37 years to reach us. Please note that a light-year is a unit of distance; it is NOT a unit of time.
To convert from light-years to kilometers, multiply the number of light-years by 9.5 x 1012.
A few kilometers. It takes light about 8 minutes to reach Earth.
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.
At a distance of 56 million kilometers, light requires 3.1 minutes to reach Mars from Earth.
Of course it travels.Then how do you expect light to reach the earth from he sun!
The average distance from the sun to the Earth is about 93 million miles (150 million kilometers). The sun's rays travel this distance through the vacuum of space to reach the Earth and provide light and heat.
If light rays did not travel through space there would be no way for them to reach Earth.
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
If you mean the light coming from the sun, it takes approx 8 or 8.5 minutes to reach earth.
Waves of heat and light, called radiation, travel to earth.
Light from Venice, like light from any other location on Earth, takes approximately 0.0000000125 seconds to reach an observer on the planet's surface. This is because light travels at a speed of about 299,792 kilometers per second in a vacuum, and the distance from Venice to an observer is relatively negligible. Therefore, the time taken for light to travel from Venice to any point on Earth is essentially imperceptible.
The speed of light in a vacuum is about 299,792 kilometers per second. It takes approximately 8 minutes and 20 seconds for light to travel from the Sun to Earth, a distance of about 93 million miles (150 million kilometers).
Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.
