Little is known of what people thought about comets before Aristotle, who observed his eponymous comet, and most of what is known comes secondhand.From cuneiform astronomical tablets, and works by Aristotle, Diodorus Siculus, Seneca, and one attributed to Plutarch but now thought to be Aetius, it is observed that ancient philosophers divided themselves into two main camps.
[6] [7] [8] Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons. As part of the Voyager program and like its sister craft Voyager 2 , the spacecraft's extended mission is to locate and study the regions and boundaries of the outer heliosphere and to ...

Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation.
The Luna programme was the first successful lunar programme, its Luna 1 (1959) being the first partially successful lunar mission The first image taken of the far side of the Moon, returned by Luna 3 (1959) Missions to the Moon have been numerous and include some of the earliest space missions, conducting exploration of the Moon since 1959.
Galileo 's prime mission was a two-year study of the Jovian system, but on March 26, 1993, while it was en route, astronomers Carolyn S. Shoemaker, Eugene M. Shoemaker and David H. Levy discovered fragments of a comet orbiting Jupiter, the remains of a comet that had passed within Jupiter's Roche limit and had been torn apart by tidal forces.
The comet was discovered in the constellation of Equuleus by Father Nicolas Sarabat, a professor of mathematics, at Nîmes in the early morning of August 1, 1729. [7] At the time of discovery the comet was making its closest approach to Earth at a distance of 3.1 AU (460 million km; 290 million mi) and had a solar elongation of 155 degrees.
