A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation. It is the force carrier for the electromagnetic force, even when static via virtual photons.he energy of a system that emits a photon is decreased by the energy of the photon as measured in the rest frame of the emitting system, which may result in a reduction in mass in the amount. Similarly, the mass of a system that absorbs a photon is increased by a corresponding amount.
THE SOLAR SYSTEM WIKI. Pluto. 134340 Pluto, more commonly known simply as Pluto, is the second-largest known dwarf planet in the Solar System, and the tenth largest observed body directly orbiting the Sun.

Uranus is the 7th planet in the Solar System, and the first planet discovered beyond the 5 planets that are visible with the unaided eye. So, who discovered Uranus?The discoverer was Sir William Herschel, who found it on March 13, 1781.Sir William Herschel. Even though Uranus is dim, itâs actually possible to see with the unaided eye in very dark, clear skies. But even so, nobody had ever officially recorded the movement of Uranus, so Herschel is the discoverer.ranus is the 7th planet in the Solar System, and the first planet discovered beyond the 5 planets that are visible with the unaided eye.
