"Lada Terra is named after Lada, the Slavic goddess of love. Lada Terra is one of eight distinct regions on the surface of Venus. Ishtar Terra and Aphrodite Terra are the other significant terrae of the planet, located near the northern polar region and the equator, respectively. Lada Terra has a diameter of . and covers most of the south pole region on Venus. The region consists of heavily deformed terrains indicating crustal deformation processes effecting the area in the past. The lowlands are much smoother terrain with very little deformation, which scientists postulate to be relatively young lava flow"
"Olympus and celebrated by the ancient Greeks for its beauty. The International Astronomical Union (IAU) formally designated the region Tempe Terra in 1979. ""Terra"" (pl. terrae) is a Latin descriptor term used in planetary geology for continent-like highland regions (i.e., extensive land masses) on other planets. Tempe Terra is located in the eastern half of the Arcadia quadrangle (MC-03) and the western edge of the Mare Acidalium quadrangle (MC-04) in Mars' western hemisphere. It is centered at and spans about 2,700 km at its broadest extent. The region extends from about 30° to 54°N and from 265° to 310°E, covering"
"Geology of solar terrestrial planets The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Earth is the only terrestrial planet known to have an active hydrosphere. Terrestrial planets are substantially different from the giant planets, which might not have solid surfaces and are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. Terrestrial planets have a compact, rocky surfaces, and Venus, Earth, and Mars each also have an atmosphere."

In literary uses, particularly in poetry, it may be ambiguous as to whether the goddess, a personification, or the common noun is meant. This article preserves the usage of the ancient sources regarding ""Tellus"" or ""Terra"". The two words ""terra"" and ""tellus"" are thought to derive from the formulaic phrase ""tersa tellus"", meaning ""dry land"". The etymology of ""tellus"" is uncertain; it is perhaps related to Sanskrit ""talam"", ""plain ground"". The 4th-century AD Latin commentator Servius distinguishes between ""tellus"" and ""terra"" in usage. ""Terra,"" he"

"Lada Terra Lada Terra is a major landmass near the south pole of Venus which is centered at 60°S and 20°E and has a diameter of . It is defined by the International Astronomical Union as one of the three ""major landmasses,"" or terrae, of Venus. The term ""landmass"" is not analogous to the landmass on Earth, as there are no apparent oceans on Venus. The term here applies to a substantial portion of land that lies above the average planetary radius, and corresponds to highlands. The broad region of Lada Terra contains massive coronae, rift zones, and volcanic plains"
"Aphrodite Terra Aphrodite Terra is a highland region on Venus, near the equator. Aphrodite Terra is named after the goddess of love, the Greek equivalent of the Roman goddess Venus. It is about the same size as Africa, and much rougher than Ishtar Terra. The surface appears buckled and fractured which suggests large compressive forces. There are also numerous extensive lava flows. Channels cross this terrain and some have an interesting bow shape to them. Aphrodite Terra also has mountain ranges but they are only about half the size of the mountains on Ishtar. Aphrodite Terra has two main regions:"
"Terra (mythology) In ancient Roman religion and myth, Tellus Mater or Terra Mater (""Mother Earth"") is a goddess of the earth. Although Tellus and Terra are hardly distinguishable during the Imperial era, ""Tellus"" was the name of the original earth goddess in the religious practices of the Republic or earlier. The scholar Varro (1st century BC) lists Tellus as one of the ""di selecti"", the twenty principal gods of Rome, and one of the twelve agricultural deities. She is regularly associated with Ceres in rituals pertaining to the earth and agricultural fertility. The attributes of Tellus were the cornucopia, or"

The Beta Caeli system is similar to our real-life solar system, with a barren, rocky inner planet, terrestrial planets in the habitable zone of the inner system, followed by gas giants in the outer system that first increase and then decrease in size, and a tiny rock outermost. The naming of the Caelian planets closely matches that of naming planets in our solar system. But while our system uses the names of Roman deities (except for Uranus), Caeli has Greek ones; Gaea is the Greek goddess of the Earth, and Rhea is her daughter. In addition, as"
"Tempe Terra Tempe Terra is a heavily cratered highland region in the northern hemisphere of the planet Mars. Located at the northeastern edge of the Tharsis volcanic province, Tempe Terra is notable for its high degree of crustal fracturing and deformation. The region also contains a large number of small shield volcanoes, lava flows, and other volcanic structures. The region is named after the albedo feature ""Tempe,"" first used by astronomer E.M.

The planets of the Solar System are divided into two groups: the four inner planets are the terrestrial planets (Mercury, Venus, Earth and Mars), with relatively small sizes and rocky surfaces. The four outer planets are the giant planets, which are dominated by hydrogen and helium and have lower mean densities. These can be further subdivided into the gas giants (Jupiter and Saturn) and the ice giants (Uranus and Neptune) that have large icy cores. Most of our direct information on the composition of the giant"
"Mars Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the ""Red Planet"" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.

"Since the dawn of the Space Age, close observation by space probes has found that Earth and the other planets share characteristics such as volcanism, hurricanes, tectonics, and even hydrology. Planets are generally divided into two main types: large low-density giant planets, and smaller rocky terrestrials. There are eight planets in the Solar System. In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four giant planets, Jupiter, Saturn, Uranus, and Neptune. Six of the planets are orbited by one or more natural satellites. Several thousands of planets around other"

Mars, Enceladus and Europa are considered likely candidates in the search for life primarily because they may have underground liquid water, a molecule essential for life as we know it for its use as a solvent in cells. Water on Mars is found frozen in its polar ice caps, and newly carved gullies recently observed on Mars suggest that liquid water may exist, at least transiently, on the planet's"

New Terra's geography is made mostly of an orange sand and rock, although there are some other kinds of terrain. Since New Terra had past volcanism, it has also lava basins and has a non-native plant lifeform, part of an old failed terraforming experiment of Eden. New Terra's poles contained frozen water like Mars, and the sand may be mostly oxidized iron. The planet has been hit by many meteors and is mostly homogenized in the metal department."
"Ishtar Terra Ishtar Terra is one of two main highland regions on the planet Venus. It is the smaller of the three ""continents"", and is located near the north pole. It is named after the Akkadian goddess Ishtar. The size of Ishtar Terra is roughly between the sizes of Australia and the continental United States. On its eastern edge lies the great mountain chain Maxwell Montes, which is 11 km high, compared to Mt. Everest at 8.8 km. On one side of the mountain chain is an impact crater of 100 km in diameter filled with lava. Ishtar Terra contains"

"Terra Australis Terra Australis (Latin for ""South Land"") was a hypothetical continent first posited in antiquity and which appeared on maps between the 15th and 18th centuries. The existence of Terra Australis was not based on any survey or direct observation, but rather on the idea that continental land in the Northern Hemisphere should be balanced by land in the south. This theory of balancing land has been documented as early as the 5th century on maps by Macrobius, who uses the term Australis on his maps. Other names for the hypothetical continent have included Terra Australis Ignota, Terra Australis"
