2. Armillary sphereAn armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky, consisting of a spherical framework of rings, centred on Earth, that represent lines of celestial longitude and latitude and other astronomically important features such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere whose principal purpose is to map the constellations.
