How many times bigger is the sun

It holds The visible part of the sun is about 10, degrees Fahrenheit 5, degrees Celsius , while temperatures in the core reach more than 27 million F 15 million C , driven by nuclear reactions. Additional Information The sun is one of more than billion stars in the Milky Way. It orbits some 25, light-years from the galactic core , completing a revolution once every million years or so.

The sun and its atmosphere are divided into several zones and layers. The solar interior, from the inside out, is made up of the core, radiative zone, and convective zone. The solar atmosphere above that consists of the photosphere, chromosphere, a transition region, and the corona.

Beyond that is the solar wind, an outflow of gas from the corona. Get Started for Free Download App. Lunar Eclipse occurs only on. Which of the following is not a symptom for altitude sickness Acute mountain sickness? Olympus Mons, the biggest mountain in our solar system is located on. The moon orbits the earth every:. Titan is a natural satellite of which of the following planet? What does the colour of Star indicate? What is the position of earth in its orbit called when it is nearest to the sun?

What is the distance of sun from earth? The mean radius of the sun is , miles , kilometers , which makes its diameter about , miles 1. You could line up Earths across the face of the sun. The sun's circumference is about 2,, miles 4,, km. It may be the biggest thing in this neighborhood, but the sun is just average compared to other stars.

Betelgeuse , a red giant, is about times bigger than the sun and about 14, times brighter. Alex Young , if the sun were hollow, it would take about one million Earths to fill it. It's possible that the sun is even larger than previously thought. Xavier Jubier, an engineer and solar eclipse researcher, creates detailed models of solar and lunar eclipses to determine precisely where the moon's shadow would fall during the solar eclipse.

But when he matched actual photos and historical observations with the models, he found precise eclipse shapes only made sense if he scaled up the sun's radius by a few hundred kilometers.

Wright said different papers using a variety of methods have produced results that differ by as much as miles 1, km. The total volume of the sun is 1.

About 1. The mass of the sun is 1. And there are many, many more in the rest of the universe. Is our Sun special? It turns out that our Sun is an average sized star. There are bigger stars, and there are smaller stars. We have found stars that are times bigger in diameter than our sun.

Truly, those stars are enormous. We have also seen stars that are just one tenth the size of our sun. Our Sun is a little unusual because it doesn't have any friends. It's just one Sun surrounded by planets, asteroids, comets, and dwarf planets. But solar systems can have more than one sun. In fact, that's often the case.
