Our solar system consists of sun & eight other planets, their satellites, comets, asteroids, etc, Sun has its surface temperature about 54000C and its inner temperature is about 15×106 0C. The nuclear reaction of conversion of helium from hydrogen is the main cause of production of solar energy. Sun holds the every member of solar system by its gravitational force by lying at the center of solar system. Every planets revolve round the sun in elliptical orbit. Their velocities and distances from the sun vary in different times. Among eight planets, earth is only one. In which the life is possible to exit. The part of mercury which fall towards the sun is very hot and past away from the sun is extremely cold. It has no atmosphere. Venus has very low amount of in its atmosphere and also extremely hot. Mars contains small amount of O2 and water but no life existing in it. Other planets from Jupiter to Neptune are very add since they are very far from the sun and there is no existence of life.
The facts about the planet, their distance from the sun, period of rotation, revolution, surface are shown in the different table forms or tabulation.
The international convention of Astronomers held on 2006 in Plague of Czech Republic excluded Pluto from list of planets. It is now regarded as a dwarf planet. Thus the number of planets happened to be eight.
Some general objectives of astronomers and astrologers (Johannes Kepler) :-
In Astronomy, Kepler three laws of planetary motion are mentioned below :-
The orbit of every planet is an ellipse with the sun at a focus.
A line joining a planet and the sun sweeps out equal areas during equal internal of time.
The square of the orbital period of a planet is directly proportional to the cube of the semi major axis of the orbit.
