the earth or a planet that resembles the earth in its physical characteristics. The terrestrial planets in the solar system are the earth, Mercury, Venus, and Mars. These planets are approximately the same size, with the earth the largest.

. They are all less dense than the earth. Jupiter and Saturn, which are classified as gas giants, are composed predominantly of hydrogen and helium. Uranus and Neptune, which are ice giants, are composed predominantly of somewhat heavier elements, such as oxygen, carbon, and nitrogen.

Four massive Jovian planets (HR 8799 b, c, d, e; not the order of semi-major axis but of discovery year) have been imaged, having masses of 5-13 [M.sub.Jupiter] at 15, 24, 38, and 68 AU.

Jovian planets rotate faster than terrestrial planets.
All four Jovian planets have inner cores made of rock, metal, and hydrogen materials.
We there therefore conclude that: White dwarfs were formerly bulky planets like Jupiter and the great jovian planets, which, containing mostly hydrogen, were compressed by gravitational pressure to such a state that the energy produced within is the same as that radiated from the surface.
Furthermore, the four terrestrial planets and the four large Jovian planets are similar to one another in that they all dominate their respective parts of the solar system.
Using this equation (11), we could predict quantization of celestial orbits in the solar system, where for Jovian planets we use least-square method and use M in terms of reduced mass [micro] = ([M.sub.1] + [M.sub.2])/[M.sub.1][M.sub.2].
Eventually objects following such tracks will pass close to one of the Jovian planets, whose gravitational influence will change the introder's orbit significantly and perhaps drastically.
