WebDec 9, 2013 · The Sun is the largest star located at the center of the Solar System. It has a diameter of 1,390,000 km (Scientific notation: 3.19 x 10e6 km) and a radius of 56,378.15 km (Scientific notation: 5.6378 x 10e4 km) The sun gives off energy as electromagnetic radiation. The Sun consists of 70% hydrogen 28% helium. 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 : $${\displaystyle 1\,R_{\odot }=6.957\times 10^{8}{\hbox{ m}}}$$695,700 … See more The unmanned SOHO spacecraft was used to measure the radius of the Sun by timing transits of Mercury across the surface during 2003 and 2006. The result was a measured radius of 696,342 ± 65 kilometres (432,687 … See more Solar radii as a unit are common when describing spacecraft moving close to the sun. Two spacecraft in the 2010s include: • Solar Orbiter (as close as 45 R☉) • Parker Solar Probe (as close as 9 R☉) See more In 2015, the International Astronomical Union passed Resolution B3, which defined a set of nominal conversion constants for stellar and planetary astronomy. … See more • Astronomical unit • Earth radius • Jupiter radius See more • S.
