The planetarium is based on the HIP (Hipparcos star chart) and displays stars of 5th magnitude or higher (1465 stars), names of famous stars, and lines and names of constellations. The movements of the planets are also reproduced and lines are drawn on the trajectories of their movements. When the application is launched, an earth model is placed 50 centimeters in front of the device, based on the device's position. A celestial sphere with a radius of 200 cm is placed based on the earth model, and stars and planets are placed on the celestial sphere. The radius of the celestial sphere can be zoomed in and out. You can also view the celestial sphere from inside or outside. # Features - [x] ARKit reproduces a planetarium. - [x] The planetarium is based on the HIP (Hipparcos star chart). - [x] Displays stars (magnitude 5 or higher, 1465 stars). - [x] Famous stars are labeled with their names. - [x] Displays constellation lines and names on the celestial sphere. - [x] Draws azimuth lines on the celestial sphere. - [x] Displays the sun, moon, and five planets (Mercury, Venus, Mars, Jupiter, and Saturn) and draws lines on their trajectories. - [x] The Earth model is placed in the center of the celestial sphere with a realistic tesure. - [x] The positions of the planets are calculated (using the Horizons API) based on actual values. - [x] Observation locations can be changed (11 locations). - [x] Date of observation can be changed (2024-2028). - [x] Time can be increased or decreased with the tap of a button.
