Francesco Fontana's drawing of the supposed satellite(s) of Venus. Woodcuts from Fontana's work. The fringes of light around Venus are produced by optical effects. Neith is a hypothetical natural satellite of Venus reportedly sighted by Giovanni Cassini in 1672 and by several other astronomers in following years. It was 'observed' up to 30 ...
Venus is in Earth's sky bright enough to be visible without aid, making it one of the classical planets that human cultures have known and identified throughout history, particularly for being the third brightest object in Earth's sky after the Sun and the Moon. Because the movements of Venus appear to be discontinuous (it disappears due to its ...
Irregular moons are probably minor planets that have been captured from surrounding space. Most irregular moons are less than 10 kilometres (6.2 mi) in diameter. The earliest published discovery of a moon other than Earth's was by Galileo Galilei, who discovered the four Galilean moons orbiting Jupiter in 1610. Over the following three ...
The adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies.
524522 Zoozve (/ ˈ z uː z v eɪ / ⓘ; provisional designation 2002 VE 68) is a sub-kilometer sized asteroid and temporary quasi-satellite of Venus. [5] Discovered in 2002, it was the first such object to be discovered around a major planet in the Solar System.
Missions to Venus constitute part of the exploration of Venus. The Soviet Union , followed by the United States , have soft landed probes on the surface. Venera 7 was the first lander overall and first for the Soviet Union, touching down on 15 December 1970.
First soft landing on the far side of the Moon, lunar rover. Beresheet Israel: 11 April 2019: Israeli lunar lander crash landed on the Moon. Chandrayaan-2 India: 8 September 2019: First attempt to land near the Moon's south pole; lost contact at 2.1 km and crashed. Chang'e 5 China: 1 December 2020
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
