The earth is in an elliptical orbit around the sun, so light takes a different amount of time to reach earth depending on the time of year. Light travels at 186,282 miles per second, and the average distance is 92,957,000 miles. This means its light takes about 8 minutes and 20 seconds to get here.
The nearest star currently, Proxima Centauri, is 4.3 light years from earth. This means that it will take 4.3 years from the light from Proxima Centauri to reach earth. The empty space is truly immense!

Light from our sun takes 8 minutes to reach earth. Light from the next closest star takes 4 years to reach earth.

The average distance from Earth to Sun is about 93,000,0000 miles. The speed of light is 186,000 miles per second. The equation you need is velocity * time = distance.
Since the distance to stars is typically measured in light-years and the nearest star is about 4.3 light-years away, the time is about 4.3 years.

First, calling it a "very undesirable day on the workplace" would not hide it. inspite of the undeniable fact that it would not kill all life on earth. The microbes got here upon kilometers below the floor, and the others got here upon close to hydrothermal sea floor vents won't even word. yet supernovae do no longer happen for in basic terms any action picture star. working example, Sirius is 8 gentle years away, yet is barely slightly extra super than the sunlight. It won't explode. What you rather need is a Wolf-Rayet action picture star, with this is axis of rotation pointed at us. From ten gentle years, that should fairly injury. The gamma ray burst on my own ought to sterilize the life on 0.5 the planet. And the wear and tear to the ozone layer could be planet extensive. yet fortuitously, there are not any stars like that nearby. inspite of the undeniable fact that evidently there is one. WR 104 is in line with possibility 8,000 gentle years away, and pointed at us. guess what the "WR" letters stand for? we gained't be attentive to if it has already exploded. in actuality, the way area-time works, there is not any customary physique of reference for time. It hasn't exploded. If and while the sunshine gets right here, that's while it happens. fortuitously, it ought to leave out. it ought to no longer even produce a gamma ray burst. by making use of the time it happens, we'd be waiting to guess while, and placed up some variety of safeguard. i'm happy this is in Sagittarius, that's extremely low interior the southern sky for me on the optimal, and somewhat a number of the time this is below my horizon.
