How many diameters is the sun

On Feb. In Voyager 1 became the first spacecraft to enter interstellar space. Now, it's yielding new insights into what that frontier is like. This was the first direct measurement of the Venusian atmosphere in nearly 30 years — and it looks quite different from Venus past. A suite of scientific balloons is about to lift off carrying instruments that will help scientists understand the connection between the Sun and Earth.

Zipping through space at close to the speed of light, Solar Energetic Particles, or SEPs, are one of the main challenges for future human spaceflight. Zodiacal light is sunlight reflected toward Earth by dust orbiting 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. The sun contains Lissauer, authors of the textbook " Planetary Sciences ," to refer to the solar system as "the sun plus some debris.

The Sun is , miles 1,, kilometers across. This is about times the diameter of Earth. The Sun weighs about , times as much as Earth. It is so large that about 1,, planet Earths can fit inside of it. If you divide the volume of the sun by the volume of the Earth, you get that roughly 1. Betelgeuse Betelgeuse, which happens to be the 9th brightest star in the sky, is much larger than our Sun. The radius of this star is up to times than of our sun. That means if Betelgeuse was placed where our sun is now, it would eat Jupiter.
