answer:The light of Antares reaches earth in 600 liht years.
About 8 minutes
Several thousand years.
Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.
4.37 years. the star is Alpha Centauri ---- That's wrong. The closest star is the sun and it takes 8.3 minutes for light to reach us. when phrased nearest star it can be a trick question.. Alpha Centauri is the nearest star besides the Sun.
The answer is right there in the words of the question. Radio and light are the same physical phenomenon, and they travel at the same speed. The star is 5 light years away. That means the distance that light ... and radio ... travel in five years. It takes light from the star 5 years to reach us, and it takes radio from us 5 years to reach the star.
It takes light 42.2 years for light from Capella to reach us
Antares (Alpha Scorpii) is a red supergiant star in the constellation Scorpius.It is approximately 600 light years from us.
About 8 minutes
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
Several thousand years.
A little over 8 minutes. See link.
Light from the Sun reaches us in a little over 8 minutes, if that's what you were asking.
8 million years. A light-year is the distance light travels in a year.
It's highly unlikely. Antares is not likely to go supernova for at least a million years. However, because of it's distance from us - 600 light years, it may have already gone supernova and we just haven't seen it yet.
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
Planet Antares program is a hit with us... we are having their machines at local businesses and establishments and they are doing great.. Chris
Yes but only about 1.3 seconds ago as this is how long light takes to reach us from the Moon.
