The present invention relates to an apparatus for observing phase changes of an inferior planet and a superior planet. According to the present invention, the phase changes of the inferior and superior planets that rotate about a sun model in an upper portion of a main body can be three-dimensionally observed and the phase changes of the inferior and superior planets can be intuitively understood. The present invention includes a main body (10) having a space portion (11) therein and having the form of a rectangular body, a central rotating plate (20) disposed at an exposed drive shaft (a), an upper portion of the drive shaft (a) being exposed with a motor (m) disposed at the center of the space portion (11) and the drive shaft (a) provided at the motor (m) penetrating a central upper portion of the main body (10), a fixing tool (30) disposed at the center of the central rotating plate (20), a planet support (40) where a planet model (b) is disposed in a bent portion (42) with one side of a horizontal portion (41) being connected to an outer circumference of the fixing tool (30) and the other side of the horizontal portion (41) being formed as the bent portion (42) vertically bent upwards, a vertical rod (50) disposed at the center of the fixing tool (30), a sun model (s) being disposed at the vertical rod (50), a front rotating plate (50) disposed in front of the central rotating plate (20), an earth disk (e) having the form of earth being disposed on an upper surface of the front rotating plate (50), and rotation means (60) connected to the front rotating plate (50a) to rotate the front rotating plate (50a) and disposed in front of the space portion (11). |
