What Does Solar Radii Mean

The solar radius is approximately 695 500 kilometres 432 450 mile or about 110 times the radius of the yird or 10 times the average radius o jupiter it varies slichtly frae pole to equator due to its rotation which induces an oblateness of order 10 pairts per.

What does solar radii mean.

Solar radius is a unit of distance used to express the size of stars in astronomy equal to radius of the sun the solar radius is usually defined as the radius to the layer in the solar photosphere where the optical depth equals 2 3. The solar system s nearest neighbor alpha centauri is a double star in a locked orbit with proxima centauri a red dwarf and alpha centauri has a solar radius of 1 227 making it slightly larger than the sun. Solar radius determinations obtained with the ccd astrolabe at tubitak national observatory p. This value is equal to 6 955 x 108 m or 0 004652 au and is usually used to compare the sizes of stars or if you wish other celestial bodies.

Blue giant stars are the upper end for stars in the main sequence and are between 10 to 100 solar radii in size. Solar radius definition the unit equivalent to the radius of the sun in which the radii of stars and other celestial objects are given. Solar radius is a unit of distance used to express the size of stars in astronomy equal to the current radius of the sun. 695 700 kilometres 432 300 miles is approximately 10 times the average radius of jupiter about 109 times the radius of the earth and 1.

This is a partial list of solar system objects by size arranged in descending order of mean volumetric radius and divided into several size classes these lists can also be sorted according to an object s mass and for the largest objects volume density and surface gravity insofar as these values are available. Solar radius is a unit of distance used to express the size of stars in astronomy relative to the sun the solar radius is usually defined as the radius to the layer in the sun s photosphere where the optical depth equals 2 3 citation needed. A characteristic distance called the schwarzschild radius.
