Sun is how many light years away

Or any other that we find in the future.

The constant "c" fell out of Maxwell's field equations. And so, if the light from the nearest star Alpha Centauri takes more than 4 years to reach us, we're seeing that star 4 years in the past.

What Is a Light-Year?

The vacuum is behaving like the superfluid, so you're not required to introduce any energy for keeping the electron in neverending motion.

In particular, I don't believe, that something like the aether actually exists - just the random Universe appears like the nested density fluctuations of particle gas for us, because it's the minimalistic deterministic approximation of observable physical reality. Related Content.

Stars other than our sun are so far distant that astronomers speak of their distances not in terms of kilometers or miles — but in light-years.

It sounds like the rest of KY isn't much better... Faint Proxima Centauri is the one that claims the honor of being our true nearest stellar neighbor at only 4.

How many light years away is the sun from earth?

EarthSky Updates on your cosmos and world. But at the moment, when such experiment violates the postulates general relativity by its very definition, then it has no meaning to ask, The meaning is just "how fast does gravity travel".

It is 13. Assuming the speed of Gravity is the same as light, then we would remain in orbit around the sun, for the exact same time as it took the light or lack of light to reach us. The answer - at present - is: Registration is free, and takes less than a minute. Read more about this image at Wikimedia Commons.

The Sun, the Alpha Centauri system, and other nearby stars all move around the Milky Way over time, and they approach and pass each other as they travel.

On top of that, the orbits are normally described with respect to the center of gravity and are not in closed form unless you neglect perturbations from the other objects in the solar system. In dense aether model every photon is behaving not only like the wave, but like the slightly more dense blob of vacuum foam as well i.

It is about 93 million miles away. This scale starts close to home but takes us all the way out to the Andromeda Galaxy, the most distant object most people can see with the unaided eye.

It would be a one-way trip that would take these lightsail-powered spacecraft 20 years.
