The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes. A small number of pioneering or notable Earth-orbiting craft. [vague] It does not include: Centuries of terrestrial telescopic observation. The great majority of Earth-orbiting satellites.
Intended to orbit the Moon and return to Earth. All first-stage engines shut down 10 seconds after launch; launch vehicle crashed and exploded on the launch pad. Spacecraft landed safely 2 kilometres (1.2 mi) from the launch site after using launch escape sequence. [68] 71: Luna 15 (E-8-5 No.401) Luna 15: 13 July 1969: Proton-K/D: Lavochkin: Lander
The first full moon of 2024 will rise on Jan. 25 at 12:54 p.m. EST. Traditionally known as the Wolf Moon because of a greater chance of hearing wolves howling during that time, according to the ...
c. 560 BCE – Anaximander is arguably the first to conceive a mechanical model of the world, although highly inaccurate: a cylindrical Earth [11] floats freely in space surrounded by three concentric wheels turning at different distances: the closest for the stars and planets, the second for the Moon and the farthest for the Sun, all conceived ...
Mayan astronomers discover an 18.7-year cycle in the rising and setting of the Moon. From this they created the first almanacs – tables of the movements of the Sun, Moon, and planets for the use in astrology. In 6th century BCE Greece, this was also discovered and was used to predict eclipses.
All planets in the Solar System, plus their major moons along some asteroids and comets, have now been visited to varying degrees by spacecraft launched from Earth. Through these uncrewed missions, humans have been able to get close-up photographs of all the planets and, in the case of landers, perform tests of the soils and atmospheres of some.
The far side of the Moon was first photographed on October 7, 1959, by the Soviet probe Luna 3. Though vague by today's standards, the photos showed that the far side of the Moon almost completely lacked maria. The first American probe to fly by the Moon was Pioneer 4 on March 4, 1959, which occurred shortly after Luna 1. It was the only ...
