The brightest areas indicate the regions with the highest concentrations of dust.Comparison of the planets and debris belts in the Solar System to the Epsilon Eridani system. Epsilon Indi - 12 light years away, two indigenous civilizations, according to … The star is estimated to be less than a billion years old.The motion of Epsilon Eridani along the line of sight to Earth, known as the The Epsilon Eridani system also includes two belts of rocky The names at that point remained unofficial, but in 2016 the IAU organised a Epsilon Eridani has been known to astronomers since at least the 2nd century AD, when Epsilon Eridani was included in several star catalogues of In 1690 Epsilon Eridani was included in the star catalogue of Based on observations between 1800 and 1880, Epsilon Eridani was found to have a large Based on apparent changes in the position of Epsilon Eridani between 1938 and 1972, In 1987, the detection of an orbiting planetary object was announced by Bruce Campbell, Gordon Walker and Stephenson Yang.Because of the proximity and Sun-like properties of Epsilon Eridani, in 1985 physicist and author Based on its nearby location, Epsilon Eridani was among the target stars for At a distance of 10.50 ly (3.22 parsecs), Epsilon Eridani is the 13th-nearest known star (and ninth nearest solitary star or Epsilon Eridani's K-type classification indicates that the spectrum has relatively weak The magnetic field on the surface of Epsilon Eridani causes variations in the The high levels of chromospheric activity, strong magnetic field, and relatively fast rotation rate of Epsilon Eridani are characteristic of a young star.During the past million years, three stars are believed to have come within 7 ly (2.1 pc) of Epsilon Eridani. Ptolemy called Epsilon Eridani ό τών δ προηγούμενος, Greekfor 'a foregoing of the four' (… The most recent and closest of these encounters was with Epsilon Eridani made its closest approach to the Sun about 105,000 years ago, when they were separated by 7 ly (2.1 pc).Dust and possibly water ice from this belt migrates inward because of drag from the stellar wind and a process by which stellar radiation causes dust grains to slowly spiral toward Epsilon Eridani, known as the The disk contains an estimated mass of dust equal to a sixth of the mass of the Moon, with individual dust grains exceeding 3.5 μm in size at a temperature of about 55 K. This dust is being generated by the collision of comets, which range up to 10 to 30 km in diameter and have a combined mass of 5 to 9 times that of Earth. At the top is the asteroid belt and the inner planets of the Solar System. This is similar to the estimated 10 Earth masses in the primordial Kuiper belt.The clumpy structure of the dust belt may be explained by gravitational perturbation from a planet, dubbed Epsilon Eridani b. The catalogue was published as part of his astronomical treatise the Almagest. And they may have been observing us for a long time. However, because of its unprepossessing appearance in the sky, and its want of a "good" traditional name to supplement its esoteric Bayer designation, Epsilon Eridani has rarely if ever been used in a general sense, either in traditional mythologies or in the arts and literature that draw inspiration from them. The star's popularity as a subject of science fiction stems not from its general cultural resonance, but from the There follow references to Epsilon Eridani as a location in space or the center of a planetary system, categorized by genre. Epsilon Eridani - 10.5 light years away, one indigenous civilization, according to Bashar. Its mass is 1.55 Jupiters, it takes 6.9 years to complete one orbit of its star, and is 3.39 AU from its star. Note however that, in terrestrial ecosystems, the The eccentricity of 0.7 suggested by some observers is inconsistent with the presence of the proposed asteroid belt at a distance of 3 AU.

Epsilon Eridani b is a gas giant exoplanet that orbits a K-type star. For a list containing many stars and planetary systems that have a less extensive list of references, see The association of a huge asteroid-sized mass of stone with an insubstantial wisp of fluff may at first blush seem like an oxymoron. It consists of civilisations from the Lyra constellation, from the Andromeda Constellation, from the Pleiades and Hyades open clusters, from Iumma [Wolf 424], Procyon, Tau Ceti, Alpha Centauri, and Epsilon Eridani, all of which are of Lyran/Vegan heritage. Epsilon Eridani b – the nearest alien world outside our solar system. There follow references to Epsilon Eridani as a location in space or the center of a planetary system, categorized by genre. The clumps in the dust occur at orbits that have an integer resonance with the orbit of the suspected planet. Its discovery was announced in 2000. Although this system was not chosen as a primary candidate for the now-canceled The orbital radius at which the stellar flux from Epsilon Eridani matches the A young star such as Epsilon Eridani can produce large amounts of Epsilon Eridani's proximity, Sun-like properties and suspected planets have made it a destination for From Epsilon Eridani, the Sun would appear as a 2.4-magnitude star in K2 (orange) star in the southern constellation EridanusSubmillimeter wavelength image of a ring of dust particles around Epsilon Eridani (above centre).

10.8 Light Years away from Earth. Epsilon Eridani is referred to as a location in space or the center of a planetary system unusually often in fiction.
