Venus is one of two planets in the Solar System, the other being Mercury, that have no moons. [23] Conditions perhaps favourable for life on Venus have been identified at its cloud layers. Venus may have had liquid surface water early in its history with a habitable environment , [ 24 ] [ 25 ] before a runaway greenhouse effect evaporated any ...
A number of near-integer-ratio relationships between the orbital frequencies of the planets or major moons are sometimes pointed out (see list below). However, these have no dynamical significance because there is no appropriate precession of perihelion or other libration to make the resonance perfect (see the detailed discussion in the section ...
The origins of the planetary symbols can be found in the attributes given to classical deities. The Roman planisphere of Bianchini (2nd century, currently in the Louvre, inv. Ma 540) [2] shows the seven planets represented by portraits of the seven corresponding gods, each a bust with a halo and an iconic object or dress, as follows: Mercury has a caduceus and a winged cap; Venus has a ...
The Venus of Laussel (c. 25,000 BP) holding a crescent shaped horn. The 13 notches on the horn may symbolize the average number of days from menstruation to an ovulation, or the approximate number of full menstrual cycles and lunar cycles per year (although these two phenomena are unrelated).

Similarly, the fourth satellite of Pluto, Kerberos, discovered after Pluto was categorized as a dwarf planet and assigned a minor planet number, was designated S/2011 (134340) 1 rather than S/2011 P 1, [21] though the New Horizons team, who disagreed with the dwarf planet classification, used the latter. H = Mercury (Hermes) [a] V = Venus; E ...
There are 293 confirmed moons in our cosmic neighborhood. By studying these worlds, astronomers hope to learn about ancient asteroid collisions, space volcanoes, and the origins of life itself.
Representation of Venus (yellow) and Earth (blue) circling around the Sun. Venus and its rotation in respect to its revolution. Venus has an orbit with a semi-major axis of 0.723 au (108,200,000 km; 67,200,000 mi), and an eccentricity of 0.007.
The lunar occultation of Venus on this date was the second lunar occultation of the Venus in the same year. [15] 2020 Venus was eclipsed by the Moon at 19 June 2020 from 9:44:15 - 10:46:12 PM (UTC+2). [16] [17] 2021 In the year 2021, Venus was occultated on 8 November. [18] The occultation was observed from the Eastern part of Asia. [19] 2023
