Venus is the second planet from the Sun, making a full orbit in about 224 days. Venus orbits the Sun at an average distance of about 0.72 AU (108 million km; 67 million mi), and completes an orbit every 224.7 days. It completes 13 orbits in 7.998 years, so its position in our sky almost repeats every eight years.
The planet's period of retrograde motion is 20 days on either side of the inferior conjunction. In fact, through a telescope Venus at greatest elongation appears less than half full due to Schröter's effect first noticed in 1793 and shown in 1996 as due to its thick atmosphere. [15] [16]
Global topographic map of Venus, with all probe landings marked (red: returned images; with additional black dot: analyzed samples). There have been 46 space missions to the planet Venus (including gravity-assist flybys). Missions to Venus constitute part of the exploration of Venus.
Map based on mapping from Pioneer Venus Orbiter and Magellan. The Venera (Russian: Вене́ра, pronounced [vʲɪˈnʲɛrə] 'Venus') program was a series of space probes developed by the Soviet Union between 1961 and 1984 to gather information about the planet Venus.

Passage de Vénus is a series of photographs of the transit of the planet Venus across the Sun on 9 December 1874. [1] They were purportedly taken in Japan by the French astronomer Jules Janssen and Brazilian engineer Francisco Antônio de Almeida using Janssen's 'photographic revolver'. [2] [3] [4] It is the oldest "film" listed on both IMDb ...
The mapping of Venus refers to the process and results of human description of the geological features of the planet Venus. It involves surface radar images of Venus, construction of geological maps , and the identification of stratigraphic units , volumes of rock with a similar age.
DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) is a planned mission for an orbiter and atmospheric probe to the planet Venus.Together with the separate VERITAS mission, which will also study Venus, it was selected by NASA on June 2, 2021 to be part of their Discovery Program.
