That is within the maximum habitable zone of a conjectured Earth-like planet orbiting Epsilon Eridani, which currently stretches from about 0.5 to 1.0 AU.
What is Epsilon with respect to planets?
The Epsilon Eridani system is the closest planetary system around a star similar to the young Sun and is a prime location to research how planets form around Sun-like stars. It is also a popular locale in science fiction. It has been featured in novels by Isaac Asimov and Frank Herbert, among others.
Is Epsilon Eridani habitable?
The planet orbiting Epsilon Eridani has a semimajor axis of 3.3 AU. Thus it is well outside the habitable zone and is very unlikely to have life, even on its eventual moons.
What kind of star is Epsilon Eridani?
Epsilon Eridani is a fourth magnitude (on the bright side, 3.73) class K (K2) ordinary, though relatively young, hydrogen-fusing dwarf. A mere 10.5 light years away, it is the 10th closest star system to the Earth.
What type of star is Eridani C?
40 Eridani A is a main-sequence dwarf of spectral type K1, 40 Eridani B is a 9th magnitude white dwarf of spectral type DA4, and 40 Eridani C is an 11th magnitude red dwarf flare star of spectral type M4. 5e.
What is the color of alnilam?
It is the 29th-brightest star in the sky (the 4th-brightest in Orion) and is a blue supergiant.
What color is the star Eridani b?
Colour. Based on the star’s spectral type of DA , 40 Eridani B’s colour and type is white white dwarf.
What type of star is Lacaille?
Lacaille 9352 (Lac 9352) is a red dwarf star in the southern constellation of Piscis Austrinus. With an apparent visual magnitude of 7.34, this star is too faint to be viewed with the naked eye except possibly under excellent seeing conditions.
What are the closest stars to Earth?
The nearest stars to Earth are in the Alpha Centauri triple-star system, about 4.37 light-years away. One of these stars, Proxima Centauri, is slightly closer, at 4.24 light-years. Of all the stars closer than 15 light-years, only two are spectral type G, similar to our sun: Alpha Centauri A and Tau Ceti.
Do exoplanets orbit our sun?
All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets.
Is Epsilon Eridani a red dwarf?
orange K-type stars such as Epsilon Eridani and finally to M-type red dwarfs thousands of times fainter than the Sun.
Is Polaris a star?
Polaris is located in the constellation of Ursa Minor, the Little Bear. It sometimes also goes by the name “Stella Polaris.” The seven stars from which we derive a bear are also known as the Little Dipper. Polaris, the North Star, lies at the end of the handle of the Little Dipper, whose stars are rather faint.
What is epsilon in English?

Where is Eridani 40?
Located around 16 light-years from Earth in the southern constellation of Eridanus, 40 Eridani A is part of a triple-star system.
Is Antares a main sequence star?
Antares is a binary system. The primary star that can be seen with your unaided eye is the red supergiant; its companion — Antares B — is a smaller main-sequence B-type star of 5th magnitude. It’s visible but easily lost in the glare of its rival and requires a fairly large telescope to see.
What is the surface temperature of the coolest star?
The hottest stars have temperatures of over 40,000 K, and the coolest stars have temperatures of about 2000 K. Our Sun’s surface temperature is about 6000 K; its peak wavelength color is a slightly greenish-yellow.
