The location of this mythical place may simply be a convention to show that a magically distant chthonic land of myth was intended in the remote past. [38] After Persephone had disappeared, Demeter searched for her all over the earth with Hecate's torches. In most versions, she forbids the earth to produce, or she neglects the earth and, in the ...
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [2] [4] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
Helios is said to have seen and stood witness to everything that happened where his light shone. When Hades abducts Persephone, Helios is the only one to witness it. [110] In Ovid's Fasti, Demeter asks the stars first about Persephone's whereabouts, and it is Helice who advises her to go ask Helios. Demeter is not slow to approach him, and ...
Trojans are bodies located within another body's gravitationally stable Lagrange points: L 4, 60° ahead in its orbit, or L 5, 60° behind in its orbit. [160] Every planet except Mercury and Saturn is known to possess at least 1 trojan. [161] [162] [163] The Jupiter trojan population is roughly equal to that of the asteroid belt. [164]
The presumed distance of the Oort cloud compared to the rest of the Solar System. The Sun is a lone, G-type main-sequence star inside the galaxy of the Milky Way , surrounded by eight major planets orbiting the star by the influence of gravity, most of them with a cohort of satellites, or moons , orbiting them.
Hades is again the name of the place, here described as "windless," and its gates, through which Pluto carried "pure Demeter's daughter" as his bride, are located in an Attic cave within the district of Eleusis. The route from Persephone's meadow to Hades crosses the sea. The hymn concludes: You alone were born to judge deeds obscure and ...
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19]
