The Sun's diameter of 1,392,000 km is 109 times the Earth's equatorial diameter of 12,756 km. To put it another way, Venus orbits the Sun at an average distance of 0.723 AU, which ranges from 0.718 AU at its closest to 0.728 AU at its farthest. The average distance between the Sun and the Earth is 1 AU or 149,598,000 km. The radius of the sun = 695,500 kilometers or 432,163.664 miles. The Sun is the Earth’s dominant source light (and thus heat) and the star about which all of the planets of the solar system orbit. Instant free online tool for Sun's radius to meter conversion or vice versa.
In our system, we have 4 terrestrial planets, 4 gas giants, and a mysterious 9th planet.

Due to such a large distance, it takes almost 8 min and 19 sec for light to reach us. 38% the size of Earth. astronomical unit (AU): An astronomical unit (AU) is the mean distance between the center of the Earth and the center of the sun. Let’s go over them, but first, here’s a quick rundown of each planet in order of size and distance from the sun. Source: wikipedia Version 4.0 - Last updated: Sunday, August 16, 2015 Divide about 435,000 by approximately 93 million to get your answer in AU. Alternately, it can be considered the length of the semimajor axis—i.e., the length of half of the maximum diameter—of Earth’s elliptical orbit around the Sun. Its mean density is 1410 kg/m 3 or 0.255 times the mean density of Earth. The Sun's radius to meter [m] conversion table and conversion steps are also listed. The actual distance varies depending on the time of year, because the Earth's orbit around the sun is not a perfect circle. The equatorial radius is the distance from the planet's/star's center to its equator and is often used to compare it with planets. The eccentricity (e) is a number which measures how elliptical orbits are. The semimajor axis (the average distance to the Sun) is given in units of the Earth's average distance to the Sun, which is called an AU. 1390000/2*149597871 is 0.00465 AU To be more accurate than that you must consider the sun is a ball of gas, measured at 1,390,000 km diameter, but has no defined surface boundary, and the earth's orbit is elliptical, and the figure for AU is 149,597,871 km as used by astronomers. The diameter of the Sun is about 1,392,000 km, or about 109 times the diameter of the Earth. The Sun has mass 1.989 × 10 30 kg and a radius of ~700,000 km. Its surface gravity is 274 m/s 2 or 28.0 times that of the Earth. Planets In Order Of Size: Size relative to Earth. The average distance between the Sun and the Earth - 149,597,870.7 km (or 92,955,807 mi) - is known as an Astronomical Unit (AU).
The solar white light images are analyzed here to estimate the Sun's radius. Solar Atmosphere Surface Gas Pressure (top of photosphere): 0.868 mb Pressure at bottom of photosphere (optical depth = 1): 125 mb Effective temperature: 5772 K Temperature at top of photosphere: 4400 K Temperature at bottom of photosphere: 6600 K Temperature at top of chromosphere: ~30,000 K Photosphere thickness: ~500 km Chromosphere thickness: ~2500 km Sun … The radius of the sun at 696,000 km is 109 times the Earth's radius. The definition of AU had been "the radius of an unperturbed circular Newtonian orbit about the sun of a particle having infinitesimal mass, moving with a … However, for other analysis, it is also possible to get access to the sunspots, their umbra and penumbra, as well as their area. If we calculate the distance in kilometers it is about 149,600,000 and 92,960,000 in miles.
Astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles). This is the distance which is known as a light year. AU: 432,450: miles: 2.254 × 10 − 8: pc: Solar radius is a unit of distance used to express the size of stars in astronomy equal to the current radius of the Sun: ⊙ = × = The solar radius is approximately 695,500 kilometres (432,450 miles) or about 110 times the radius of the Yird, or 10 times the average radius o Jupiter.
