All Surrounding Bodies In Any Star (Solar) System Are Illuminated By The Light Of Their Mothers Or Creators; The Solar Entities or Suns.
All planets orbit around the greatest centre of mass. In our solar system, that is our Sun.
The sun is a star.It's the only self-luminous body in the solar system.The gravitational force of mutual attraction between the sun and everything in a closed orbitaround it is what makes the closed orbits possible.One focus of the elliptical path of everything in closed orbit around the sun is at the center of the sun.The orbits of the planets are so nearly circular (small eccentricity) that the center, as well as both foci,of every planetary orbit is inside the sun. This isn't true of most repeating cometary orbits.
It is part of the Solar System. The Solar System includes planets, moons, comets, asteroids, a star and dwarf planets like Pluto. It's just not a planet. It never was a planet (according to the new definition).A planet is a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet."Pluto is no longer considered a planet because it does not fulfill the criteria, but Pluto never stopped being considered a part of the solar system. It still orbits the same star, although it is a very distant orbit.
On August 24, 2006, the International Astronomical Union (IAU) announced a formal definition of planet that established a tripartite classification for objects in orbit around the Sun: "small Solar System bodies" were those objects too small for their gravity to have collapsed their surfaces into a rounded shape; "dwarf planets" were those objects large enough to be rounded, but who had yet to clear their orbits of similar-sized objects; "planets" were those objects that were both large enough to be rounded by self-gravity and which had cleared their orbits of similar-sized objects.[22] Under this classification, Pluto, Eris and Ceres were reclassified as dwarf planets.[22] Makemake is one of those "crazy" planets.
None it would be hard to fit Saturn in its self without all of the other planets plus the planets aren't hollow.

Research results in no reliable information regarding the self-luminosity of any planet in the solar system. Planets do not emit light, they reflect it. If any one of the planets were capable of emitting light, it would most likely be Jupiter which is a bit of a failed star, however there seems to be no data indicating that Jupiter does more than reflect the light of the sun. Edit: Yes, it's not easy to think what this question is getting at. There's the faint "ashen light" sometimes seen on Venus. Of course the Earth is slightly luminous because of human activity. But what I think is the most likely answer is "Jupiter". That planet emits more energy than it could by just reflecting sunlight. Of course that's total energy including all radiation wavelengths, not just the optical waveband.
do it by your self dums dood

Self-illuminating would be phosphorous.
A solar heater is called a self pumping system because cold water flows down the panels by itself when hot water rises into the tank.
A faint, cloudlike, self-luminous mass of matter situated beyond the solar system among the stars. True nebulae are gaseous; but very distant star clusters often appear like them in the telescope., A white spot or a slight opacity of the cornea., A cloudy appearance in the urine.
'cause the star is self luminous and the planet is not .
