That would be roughly 16minutes 40seconds .
It takes about 997.186 seconds for light to travel across the diameter of Earth's orbit.
Light takes about 8 minutes and 20 seconds to travel from the Sun to Earth. Since the distance across Earth's orbit is roughly double the distance from the Sun to Earth, it would take light around 17 minutes to travel across the diameter of Earth's orbit.
Approx 100000 to 180000 years.
about 16 minutes and 40 seconds
It takes light approximately 8.3 minutes to travel across the diameter of Earth's orbit around the sun, which is about 186 million miles. This value is known as the astronomical unit (AU) and is used as a standard unit of measurement in astronomy.
It can travel across the vacuum of space.
Approximately 100,000 light years across.
The Milky Way is approximately 100,000 light-years in diameter. This means that if you could travel at the speed of light, it would take you 100,000 years to cross from one side of the galaxy to the other.
The Milky Way is about 100,000 light years in diameter and about 1000 light years thick.
Depending on the type of nebula, they can range from a light year across to over a 100 light years in diameter.
Depends witch star it comes from. The closest stars light will only take 7 years but most of the stars (that are relatively closeby compared to the light of other galaxies) will take 200 or more.
The most recent measurements put the diameter of Andromeda Galaxy at 141,000 light-years across. The Milky Way is estimated to be 100,000 light-years across.
