Question

How long does it take light to travel between earth and the nearest star?

Answer 1

8.3 minutes

Step-by-step explanation:

In the solar system the Sun is the nearest Star to the Earth.

The Speed of light is 300,000 kilometers/second.

The distance is given as 147.67×10⁶ km

The time it will take for the light from the star to reach Earth is :

T= distance / speed

147.67×10⁶/300000 = 492.233 seconds

The nearest star to Earth is the Sun and it takes about 8.3 minutes for its light to reach the Earth.

Answer 2

It takes 8.204 minutes for light to travel from the Sun to Earth

Step-by-step explanation:

The speed of light is 300000 km/s and the nearest star to the Earth is the Sun which is 149.67 million km. therefore it takes about

147.67×10⁶/300000 = 492.233 seconds for light from the Sun to reach Earth or 8.204 minutes

The other next nearest star is Alpha Centauri which is 4 light years away
