Originally Answered: What is the oldest name for earth? The name of our planet originates from Roman mythology. Earth, "Tellus", in ancient Rome was the personification of the nurse Earth, sometimes honored under the name of Terra Mater (Mother Earth), mostly identified with the Greek goddess Gaia (Gea).
The ancient Greeks personified the sun as a handsome god named Helios. His astronomical pedigree was impeccable: He was the son of the Titan Hyperion and the Titaness Theia. Helios was also the brother of Selene, the goddess of the Moon, and Eos, the goddess of the dawn.
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
Mars is named for the ancient Roman god of war. The Greeks called the planet Ares (pronounced Air-EEZ). The Romans and Greeks associated the planet with war because its color resembles the color of blood. Mars has two small moons.
Five planets have been known since ancient times — Mercury, Venus, Mars, Jupiter, and Saturn. The first new planet discovered was Uranus. It was discovered by the English astronomer Sir William Herschel in 1781.

Mercury is named after the messenger for their gods. The Roman Mercury had wings on his helmet and shoes. He could travel very quickly from place to place. The planet Mercury moves quickly around the sun.
Mars: What We Know About the Red Planet. Mars is the fourth planet from the sun. Befitting the Red Planet's bloody color, the Romans named it after their god of war. In truth, the Romans copied the ancient Greeks, who also named the planet after their god of war, Ares.
The 12 Roman Gods were: Jupiter, Juno, Mars, Mercury, Neptune, Venus, Apollo, Diana, Minerva, Ceres, Vulcan, and Vesta. Jupiter held thunderbolts in his hands, which he could throw from the sky.
One of the most popular suggestions for the origins of the term 'Africa' is that it is derived from the Roman name for a tribe living in the northern reaches of Tunisia, believed to possibly be the Berber people. The Romans variously named these people 'Afri', 'Afer' and 'Ifir'.
The Roman goddess' Greek counterpart is Gaia, from the Ancient Greek Γα?α, a poetic form of Γ? Gē (“land, earth”), from which English developed its geo- prefix, as in geography and geology.
Like all the planets, Mercury is named after one of the Roman gods, which were based on the gods worshipped by the Ancient Greeks. The Roman god Mercury was the son of Maia Maiestas and Jupiter in Roman mythology, and most of his aspects were based on the Greek god Hermes.
Tellus, also called Terra Mater, ancient Roman earth goddess.
The Greek root word ge, commonly used in the English prefix geo-, means “earth.” This Greek root is the word origin of a good number of English vocabulary words, including geology, geography, and geometry.
Earth is old. The sun is old. As much as half of all the water on Earth may have come from that interstellar gas according to astrophysicists' calculations. That means the same liquid we drink and that fills the oceans may be millions of years older than the solar system itself.
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. Jupiter, Saturn, Mars, Venus and Mercury were given their names thousands of years ago. The other planets were not discovered until much later, after telescopes were invented.
The names Moon and month both come from the ancient Greek name for the Moon, Mene. There have been other names for the Moon, like Selene and Luna. Selene was the Greek goddess of the Moon. Luna was the Roman goddess of the Moon.
According to GISS, the global mean surface air temperature for that period was estimated to be 57 F (14 C). That would put the planet's average surface temperature in 2017 at 58.62 F (14.9 C).
Earth is the fourth smallest of the planets—though in terms of the rocky planets, it's the largest—but it's the most dense. Jupiter is the largest planet in the solar system, but it's Saturn—the solar system's second largest planet—that takes the prize for least dense.
IntroductionVenus is the second planet from the Sun and our closest planetary neighbor. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.

A special planet: the habitable EarthWhat makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
The Roman year originally had ten months, a calendar which was ascribed to the legendary first king, Romulus. Tradition had it that Romulus named the first month, Martius, after his own father, Mars, the god of war.
Dirt is earth or soil — it's the substance that makes up the dry surfaces of our planet.
Much of Earth's water is thought to have come from asteroids impacting the planet early in its history. Most of Earth's water did come from asteroids, but some also came from the solar nebula. As Wu noted: For every 100 molecules of Earth's water, there are one or two coming from the solar nebula.
