Realistic rendering of the red dwarf Rao and Krypton below. Unlike our white sun that has a yellow corona, a red dwarf is yellow with a red corona.
Rao is the name of the fictional red star in the Kryptonian solar system. Although it is too faint to be seen with the naked eye because of its apparent magnitude, it may be observed using a telescope. Although Rao has a very low average luminosity compared to the sun, generally yellow with a red corona of light it may also briefly turn to a dimmer red or a brighter white. This is because it is a flare star that undergoes random dramatic increases in brightness due to intense magnetic activity.The star's magnetic field is created by convection within the stellar body, resulting in X-ray flare emissions similar to that produced by the Sun only 50% more powerful. Despite all this activity the mixing of fuel at Rao's core is relatively low in energy-production. This means that it will be a main-sequence star for another four trillion years, or nearly 300 times the current age of the universe.

Post-Crisis Continuity
Rao's humanoid incarnation, while speaking to Despair of the Endless billions of years ago.
The sun was created by a race of gaseous beings called the Sun-Thrivers who drew matter from far galaxies. However, the sun was unstable, so the Sun-Thrivers created planets out of solar matter, using their gravities to stabilize the turbulent sun storms. Of all the planets in orbit, Krypton was the most powerful.[1]
Rao was given the idea by Despair of the Endless-- another diety, controlling all despair-- to allow the civilization of Krypton to flourish, and then for the planet to be destroyed; and for only one inhabitant to survive. This was considered to be "artful". ("The Sandman: Endless Nights")
It has been suggested that there is a direct lineage between Rao and the house of El. That is to say, that Jor-El and Superman and their entire family may be descended from the god of their people.
New 52 Continuity
Rao is located about 27 light-years from Earth, at LHS-2520. As such Neil Degrasse Tyson was able to organize a worldwide collaboration to use many telescopes in conjunction to get a high-quality image of Krypton's destruction. ("Star Light, Star Bright")
