In the background can be seen another narrow asteroid or comet belt plus an outermost belt similar in size to our solar system’s Kuiper Belt. If your spaceship were traveling at 0.999 999 5 times the speed of light (0.999 999 5c), for example, its mass in flight (as measured by your friends on Earth) would be 1 000 000 kilograms—a thousand times its rest mass. Information regarding Metallicity and/or Mass is from the E.U. An orange-red dwarf, Epsilon Eridani spins relatively fast, with a rotational period of 11 days (compared with the Sun's 27 days).

En hypothetesche Planéit, Epsilon Eridani c genannt, gouf 2002 op Basis vun der Analys vun der Stëbsscheiwestruktur virgeschloen. Located 10.5 light-years away in the southern constellation Eridanus, the star Epsilon Eridani, Eps Eri for short, is the closest planetary system around a star similar to the early Sun. In the right foreground, a Jupiter-mass planet is shown orbiting its parent star at the outside edge of an asteroid belt. The system's inner asteroid belt appears as the yellowish ring around the star, while the outer asteroid belt is in the foreground. These observations indicated that the planet has a mass 1.5 times that of Jupiter and shares the same plane as the outer dust disk observed around the star. Epsilon Eridani b is a gas giant exoplanet that orbits a G-type star. Epsilon Eridani is located about 10 light-years away in the constellation Eridanus. Điều này cho phép nó để được nhìn thấy từ hầu hết các bề mặt của Trái đất. At only 10 light-years away, Epsilon Eridani b is a great place to start. D'Entdecker hu seng Mass mat 1,2 ± 0.33 facher Jupitermass betëmmt. The information was obtained as of 12th Feb 2017. Epsilon Eridani is the closest star known to have a planet: and maybe two of them. References References

Epsilon Eridani (ε Eridani, viết tắt Epsilon Eri, ε Eri), cũng có tên là Ran, là một ngôi sao trong chòm sao [[Eridanus phía nam, ở một góc nghiêng của 9,46 ° phía nam của đường xích đạo trời. Its discovery was announced in 2000. Epsilon Eridani is the nearest, reasonably Sunlike star, having about three-quarters the mass of the Sun and one-third the luminosity. The only downside to that itinerary is that it's an extremely unlikely candidate for hosting life. It lies in the constellation Eridanus at a distance of just over 10 light-years. Epsilon Eridani (ε Eridani, abbreviatit Epsilon Eri, ε Eri), an aa named Ran, is a starn in the soothren constellation o Eridanus, at a declination o 9.46° sooth o the celestial equator. At 10.5 light-years from its sister system, the Sol system and is one of the closest neighbors of humanity's homeworld. The Epsilon Eridani system is a planetary system situated 10.5 light-years from Earth, is identified as a region in FLEETCOM Sector One. It is the only system that has both precise Doppler data and long-baseline astrometric positional observations, which combined yield the orbital tilt and the true planetary mass. 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. Not only is the planet a gas giant similar to our own Jupiter or Saturn, but it might follow an orbit that brings it close to and far from its parent star. It was home to several habitable planets colonized by the Unified Earth Government, most notably Reach. Ở … Artist’s illustration of the Epsilon Eridani system showing Epsilon Eridani b. It is visible in the night skies with the naked eye. The derived orbit from these measurements is eccentric: either 0.25 or 0.7.
