OBSERVATORIES

More than 1800 organisations,institutes and laboratories are doing astronomical research and observations in the world. Among them, more than 300 are official professional observatories owning telescopes and performing regular observations. About 1000 organisms, associations and institutions have pedagogical purposes and welcome pupils, students, general public and amateur astronomers.

We will make now a tour in the observatories and institutes working in fields related to solar system, natural satellites, celestial mechanics and ephemerides.
