First of all, a light year is not a measure of time. It is a measure of distance. A light year is the distance light travels in a year.
Second, it depends on the distance of the star. The closes star to us is the sun. Light from it takes 8 minutes to reach Earth. The next nearest is Proxima Centauri, from whigh light takes about 4 years to reach us. The stars we see at night are a few hundred light years from us. However, the vast majority of stars in the universe are to far away to be visible to the naked eye. The most distant stars are billions of light years away.
Starlight travels through space in the form of electromagnetic waves. These waves carry energy from the star and are able to travel through the vacuum of space due to the lack of particles that would impede their progress.
The speed of light [ c ] is a constant at 186,000 miles per second.
All stars are stationary (they do not move) if you are asking "how fast does the light of a star travel" then the speed of light is 186,282 miles per second.

What kind waves can travel through space?
Electromagnetic waves, such as light and radio waves, can travel through space because they do not require a medium to propagate. These waves can travel through the vacuum of space and do not need a material substance to carry them.
Do electromagnetic waves travel through empty space?
Yes, electromagnetic waves can travel through empty space. This is because they do not require a medium to propagate, unlike sound waves which need a medium (such as air) to travel through. Electromagnetic waves can travel through a vacuum, allowing them to move through space.
Which do not travel through empty space?
Sound waves do not travel through empty space because they require a medium, such as air, water, or a solid, to propagate. Similarly, mechanical waves like seismic waves also need a medium to travel and cannot propagate through empty space.
What travels through empty space?
Electromagnetic waves, such as light and radio waves, can travel through empty space. These waves do not require a medium to propagate, allowing them to travel through the vacuum of space.
What is the energy that can travel through empty space or through matter?
Electromagnetic energy, such as light and radio waves, can travel through empty space or through matter. This type of energy does not require a medium to propagate and can travel vast distances through the vacuum of space.
By which process does starlight travel through space?
Starlight travels through space in straight lines at the speed of light. It can be affected by the gravitational pull of massive objects, causing it to follow curved paths around them, a phenomenon known as gravitational lensing.
By which process does starlight travel though space?
Starlight travels through space in a straight line until it encounters an object, such as a planet or gas cloud, that can deflect or absorb it. The path of starlight can be influenced by the gravitational pull of massive objects, causing it to bend slightly.
How does the lack of an atmosphere in space affect the reflection of starlight?
The lack of atmosphere in space means there are no particles to scatter or absorb starlight. This allows starlight to travel through space unaffected, resulting in clearer and sharper images of stars as observed from telescopes or spacecraft.
How starlight travels through space?
Electromagnetic energy PS: What does this have to do with religion and spirituality?
What type of material can travel through space?
Sound and Light can travel through space.
What type of waves travel through space?
Sound waves cannot travel through space.
Can a black hole travel through space?
Yes, a black hole could travel through space.
What can travel through space without a(n) medium?
Electromagnetic waves can travel through space without a medium.
Where does an asteroid travel?
Asteroids travel through space.
Can radiation travel though space?
All types of radiation can travel through space.
What parts of space can light waves travel through?
Light can travel through any parts of space, there is no part that it is excluded from.
Can light travel through space?
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.
