If it travel to the Sun, it would have taken just over 106 days to reach it.
There are galaxies millions of light-years away, which means the light we’re seeing left the surface of those stars millions of years ago.

It’s about 8 minutes, the distance between the sun and the Earth because light travels at about 1 billion km/h and the sun is about 150 million km away from the Earth.
This will take, 5x10^21 x 3 x10^-11 = 1.5 x 10^11 seconds or since The unmanned NASA New Horizon probe traveled away from the Earth on its path to Mars and beyond at 36,373 mph.

Very approximately, this means that to travel the radius of the Sun, a photon will have to take (696,000 kilometers/1 centimeter)^2 = 5 x 10^21 steps. However, its equator spins the fastest and takes about 24 days to rotate, while the poles take more than 30 days. As you look outward into space, you’re actually looking backwards in time.
In a car travelling 140 km/h it would take you 123 years. You'd expect sunspots to be hot, but they're actually cold areas on the sun's surface, though "cold" is a relative term.
interior of the sun is not at constant density so that the steps taken in the 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. Menstrual Science: periods, pills, poverty, Coronavirus: sex differences in the spotlight. It takes 24 hours for the Earth to make a full rotation, but since the sun isn't a solid object like a planet, its rotation is harder to pinpoint.

How long does it take for heat to reach us from the sun? 7-10 days: "sun poisoning" is just severe sunburn. Yes, but the infra red has dissipated.And "No" the Sun generates its own heat. Within just 15 minutes of being in the sun, you can be sunburned. If you’d like more info on the Sun, check out NASA’s Solar System Exploration Guide on the Sun, and here’s a link to the SOHO mission homepage, which has the latest images from the Sun.

The length of time it takes to get to the Sun depends upon the speed of the object going to the Sun. This also does my take into account things like solar wind and the heliosphere which tend to work against emissions from outside the solar system. ©The Naked Scientists® 2000–2020 | The Naked Scientists® and Naked Science® are registered trademarks created by Dr Chris Smith. it does not impact any phenomena we measure with the exception of the densities are highest. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth. Here's the math.
factor of 10!
You probably know that photons are created by fusion reactions inside the Sun’s core. The answer is that if his starting point and ending point are separated by 10 steps, it will take him -- on average -- 100 steps to get there -- that's 10 squared. Future US, Inc. 11 West 42nd Street, 15th Floor, It takes light approximately 8 minutes and 20 seconds to travel from the Earth to the Sun.

Sunspots occur where the sun's plasma interacts with its magnetic field and can lead to solar flares and other types of solar storms.
For severe cases, sun poisoning may take 10 days or longer to resolve, and mild cases of sun poisoning may take up to 3 days to get rid of the symptoms along with skin peeling. Is the Coronavirus Crisis Increasing America's Drug Overdoses?
The inner parts of the sun also spin faster than the outer layers, according to NASA.
What you probably don’t know, is that these photons striking your eyeballs were ACTUALLY created tens of thousands of years ago and it took that long for them to be emitted by the sun. Pagkakaiba ng pagsulat ng ulat at sulating pananaliksik?
The probability of those things occurring by chance are considered impossible by many, many orders of magnitude. Thank you for signing up to Live Science.
Dr. Joseph Eastern answered. to 1 centimeter after electromagnetic effects are included.
© seconds. The actual 'mean free path' for radiation is closer But the story of light gets even more interesting, when you think about the journey light needs to make inside the Sun. Once they escaped the surface, it was only a short 8 minutes for those photons to cross the vast distance from the Sun to the Earth. At its closest point, sunlight only takes 490 seconds to reach Earth. NY 10036.
