Which was the first spacecraft to orbit the Moon?

 

          Luna 10 was the first spacecraft to not only orbit the Moon, but the first to orbit any celestial body other than the Earth. A probe sent to study the lunar environment; it confirmed the Moon’s lack of atmosphere. It also made the first measurements of the lunar soil composition.

          Luna 10 was a predecessor to astronaut orbital missions. It was 1.5 metres tall and the base was 75 centimetres in diameter. It contained seven instruments including devices for measuring infrared emissions from the Moon, low energy X-ray detectors, and a bank of charged particle detectors. A radio system was installed in Luna 10 for gravitational and radio occultation studies.
