The invention provides a 
solar system planetary 
planetarium display 
system which comprises 
solar system star and planetary models including Sun, Mercury, Venus, Earth, Moon, Mars, Jupiter, Saturn, Uranus and Neptune models. Projection in a model is adopted by the Sun model, the content of a projection video comprises the structure of the Sun, the Sun as a source of energy, sunspots and cycles, solar activity, the lepton miracle in the Sun, sun 
storm and the Sun and the Earth. Spherical touch control is used by the mercury model, and the content of a projection video comprises the internal structure of Mercury, 
topography, star 
magnetic field, the planetary extremes and star motion. Spherical touch control is used by the Venus model, and the content of a projection video comprises star characteristics, basic parameters, volcanic distribution, an atmospheric environment and physical observation. Internal projection is adopted by the 
Earth model, a spherical touch control is adopted by the Moon model which is associated with the 
Earth model, and the content of a projection video comprises the observation of the Earth from 
outer space, the moon, the surface of the Moon, the rotation ofthe Moon around the Earth, tides, and the origin of the Moon.
