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.
However, the increasing number of moons that were being discovered in the 21st century caused the IAU to draw up a new scheme for the outer moons. At the IAU General Assembly in July 2004, [ 2 ] the WGPSN allowed satellites of Saturn to have names of giants and monsters in mythologies other than the Greco-Roman.
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 ...
Nineteen moons are large enough to be round, and two, Titan and Triton, have substantial atmospheres The number of moons discovered in each year until November 2019 Mercury , the smallest and innermost planet, has no moons, or at least none that can be detected to a diameter of 1.6 km (1.0 mi).

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 ...
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.
Exceptions to this rule are valleys and craters on Mars and Venus; naming conventions for these features differ according to size. One feature classification, regio, was originally used on early maps of the Moon and Mercury (drawn from telescopic observations) to describe vague albedo features. It is now used to delineate a broad geographic region.
This is a list of montes (mountains, singular mons) on the planet Venus. Venusian mountains are all named after goddesses in the mythologies of various cultures, except for the Maxwell Montes. The four main mountain ranges of Venus are named Akna Montes, Danu Montes, Freyja Montes, and Maxwell Montes. These are found on Ishtar Terra.
