A3 - 1 / 40.364840, 49.833160

This is the interior space of the telescope, which is considered to be empty. In fact, the exoplanet has an atmosphere of argon gas and a landscape of mercury. The temperature and pressure on the A3 - 1's surface are high enough for mercury vapor to condense and become liquid. Under such conditions, they create flows, form river systems and other geological formations at the equator. In the cold season the surface of planet has a mirror shine.
