How far away is Epsilon Eridani from the Sun?
At a distance of 10.50 ly (3.22 parsecs), Epsilon Eridani is the 13th-nearest known star (and ninth nearest solitary star or stellar system) to the Sun as of 2014. Its proximity makes it one of the most studied stars of its spectral type.
What is the difference between the Eridanus and Orion constellation?
Above, the northern section of the Eridanus constellation is delineated in green, while Orion is shown in blue. Below, an enlarged view of the region in the white box shows the location of Epsilon Eridani at the intersection of the two lines.
Why is the sky blue in colour?
As light passes through the atmosphere the nitrogen scatteres the blue color of light as its wavelength matches the size of the nitrogen molecules in the atmosphere. This is why our sky is blue. When the sun rises it appears red at first then turns orange then to blue.
What is the modern designation for Epsilon Eridani?
Ulugh Beg carried out new measurements of Epsilon Eridani’s coordinates in his observatory at Samarkand, and quotes magnitudes from Al-Sufi (3 for Epsilon Eridani). The modern designations of its entry in Ulugh Beg’s catalogue are “U 781” and “Eri 13” (the latter is the same as Ptolemy’s catalogue designation).
