Venus has no moon, but several man-made objects orbit the planet. The name is analogous to the term geocentric orbit for an orbit around Earth and heliocentric orbit for an orbit around the Sun. The apsides of an Cytherocentric orbit are pericytherion, the pericenter (analogous to perigee ), and the apocenter is named apocytherion (analogous to ...
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 modified Ranger Moon probe, it established that Venus has practically no intrinsic magnetic field and measured the temperature of the planet's atmosphere to be approximately 500 °C (773 K; 932 °F). [34] The Soviet Union launched the Zond 1 probe to Venus in 1964, but it malfunctioned sometime after its May 16 telemetry session.
The European Space Agency has officially adopted two new space missions to study Venus from its atmosphere to inner core and to search for gravitational waves.
For instance, for a large portion of names ending in -s, the oblique stem and therefore the English adjective changes the -s to a -d, -t, or -r, as in Mars–Martian, Pallas–Palladian and Ceres–Cererian; [note 1] occasionally an -n has been lost historically from the nominative form, and reappears in the oblique and therefore in the English ...
Venus has no natural satellites. [97] Earth (0.98–1.02 AU) [D 6] is the only place in the universe where life and surface liquid water are known to exist. [102] Earth's atmosphere contains 78% nitrogen and 21% oxygen, which is the result of the presence of life.
The naming of moons has been the responsibility of the International Astronomical Union's committee for Planetary System Nomenclature since 1973. That committee is known today as the Working Group for Planetary System Nomenclature (WGPSN). Prior to its formation, the names of satellites have had varying histories.
"Venus now has surface conditions that are extreme compared to Earth, with an atmospheric pressure 90 times greater, surface temperatures soaring to around 465°C (869°F), and a toxic atmosphere ...
