An orrery is a model that shows the positions of planets in a star system, usually the Solar System. This project's orrery shows the live, real-time positions of the planets. Distances are not even close to scale. Includes 15 planets in total, the eight planets of the Solar System, as well as the seven exoplanets that orbit the star TRAPPIST-1. This project shows the live positions of the planets. It uses its orbital periods and the Days Since 2000 block to estimate where they are in their orbits. You can see the names of each planet by hovering your mouse over them. The positions should be pretty accurate, although it's not even close to scale. If it was, it'd either be too big for a Scratch project, or too small to see. The project also renders the orbits as perfectly circular, but in reality, they're slightly elliptical. The exoplanet system is TRAPPIST-1. The planets in this system orbit very fast, with Trappist-1 b having an orbital period of just 1.5 days. For comparison, it takes Mercury 88 days to orbit the Sun. However, it still takes about an hour for a noticeable change in the positions of the exoplanets to occur. As such, this project is not intended to be watched continually, but to be checked intermittently. The TRAPPIST-1 system is being studied by the James Webb Space Telescope. It is sometimes considered the most studied planetary system in the universe besides our own Solar System.
