... This class is about the characteristics of stars and more importantly, how we know what we know. 1) The Sun looks much brighter than all the other stars because it is so close. It seems to have a fairly average luminosity. Other stars have luminosities that are up to a million times greater and down ...

Photons in the Sun travel such short distances that many absorptions and reemissions must occur before radiative diffusion can carry the Sun’s energy to the surface. It is at that distance from the c ...

Astronomical unit

The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun. However, that distance varies as the Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year. Originally conceived as the average of Earth's aphelion and perihelion, it is now defined as exactly 7011149597870700000♠149597870700 meters (about 150 million kilometers, or 93 million miles). The astronomical unit is used primarily as a convenient yardstick for measuring distances within the Solar System or around other stars. However, it is also a fundamental component in the definition of another unit of astronomical length, the parsec.
