The relationship between Energy(E) and momentum(P) of photon is as follows.
Photogravitational mass of central bodyEdit
To find the total absolute Momentum of light radiated for an object from mass m, we have to take into account the surface area, A(in m^{2}) of the astronomic object:
where j is known variously as the blackbody irradiance, energy flux density, radiant flux, or the emissive power and k is proportional constant. The constant of proportionality σ, called the Stefan–Boltzmann constant or Stefan's constant, is nonfundamental in the sense that it derives from other known constants of nature. The value of the constant is
where k is the Boltzmann constant, h is Planck's constant, and c is the speed of light in a vacuum. Thus at 100 K the energy flux density is 5.67 W/m^{2}, at 1000 K 56,700 W/m^{2}, etc.
Define Photogavitational mass of central body as follows,
Where is inertial mass and is photogravitational constant. However without bulk, the surface temperature couldn't be maintained. With T cube inertial mass assumption,
and Photogravitational mass of centrifugal body can be written as follows.
Thus Momentum from unit area
The difference between surface temperature and core temperature is also important for near field gravity. with lattitude, it increases resulting in value between 9.78 and 9.82 m/s2
Attenuation by the spaceEdit
Unit time areal density of momentum is normally dependent on Inverse square of distance for perfect vacuum without any absorption, scattering and reflection by dark matter. Optical attenuation by Solid is described by the factor of exp(kr). Although 1/rr factor is abnormal for opotics. density variation of dark matter from the astronomic object isn't negligible and is proportianl to ln(rr)/r which is primitive.
Function 2lnr/r has a minimum about 0.74 at r=2.73 and asymtotically approaches to 0.
Density function inbetween the astronomical objects may be rewritten.
where 0.74 and r is also normalized value of distance r=d/
To find & ; out is very necessary to proceed. Temperature and mass density against altitude from the NRLMSISE00 standard atmosphere model shows that local minimum is between 100km and 160km.
GravityEdit
Photogravitational force might be deduced as follows.
where phi is photogravitaional constant and Ts is surface temperature of astronomic object.
To take care of differential effect, It can be modified as follows.
if Electrogravitational emission of centripetal body stimulated by photogravity of the central body might be proportional to mass rather than Ts biquadrate.
We modify the above equation as follows,
Then, inverse biquadrate force is
Sunlight intensity in the Solar SystemEdit
Different bodies of the Solar System receive light of an intensity inversely proportional to the square of their distance from Sun. A rough table comparing the amount of light received by each planet on the Solar System follows (from data in [1]):
Planet  Perihelion  Aphelion distance (AU)sq.  Solar radiation maximum and minimum (W/m²)  Orbital radius(biq) 
Inverse biquadrate


Mercury  0.3075 – 0.4667  14,446 – 6,272  0.565  13414.5 
Venus  0.7184 – 0.7282  2,647 – 2,576  0.826  2936.6 
Earth  0.9833 – 1.017  1,413 – 1,321  1.0  1367.0 
Mars  1.382 – 1.666  715 – 492  1.287  498.26 
Jupiter  4.950 – 5.458  55.8 – 45.9  2.689  26.147 
Saturn  9.048 – 10.12  16.7 – 13.4  3.870  6.0941 
Uranus  18.38 – 20.08  4.04 – 3.39  5.885  1.139682 
Neptune  29.77 – 30.44  1.54 – 1.47  7.705  0.387859 
The actual brightness of sunlight that would be observed at the surface depends also on the presence and composition of an atmosphere. For example Venus' thick atmosphere reflects more than 60% of the solar light it receives. The actual illumination of the surface is about 5,000–10,000 lux, comparable to that of Earth during a dark, very cloudy day.
Sunlight on Mars would be more or less like daylight on Earth wearing sunglasses, and as can be seen in the pictures taken by the rovers, there is enough diffuse sky radiation that shadows would not seem particularly dark. Thus it would give perceptions and "feel" very much like Earth daylight.
For comparison purposes, sunlight on Saturn is somewhat slightly brighter than Earth sunlight on the average sunset or sunrise. Even on Pluto the Sun would be still bright enough to almost match the average living room. To see the Sun shine as dim as the full Moon on the Earth, a distance of about 500 AU (~69 lighthours) is needed: there is only a handful of objects in the solar system known to orbit farther than such a distance, among them 90377 Sedna and (87269) 2000 OO67.
