Formerly known as Ran, Epsilon Eridani is a main-sequence star located in the southern constellation of Eridanus. If you need the diameter of the star, you just need to multiple the radius by 2. Epsilon Eridani is a star in the southern constellation of Eridanus. Reach, also known as Epsilon Eridani II, [3] [7] [8] is a human colony world in the Epsilon Eridani system, located within the Inner Colonies and is the sister planet of Earth itself. Epsilon Eridani is a planetary system orbiting a orange K-class star. The outermost comet ring is too far out to be seen in this view, but comets . confirming fundamental properties of the exoplanet host star {epsilon} eridani using the navy optical interferometer It has 85% of the Sun's mass, is roughly the same size, but has only 28% of its luminosity, and is 10.522 light years distant. At a distance of 10.5 light years from Earth, it has an apparent magnitude of 3.73, allowing people to see it with the unaided eye. thats why they are called EXO planets. Epsilon Eridani b is a gas giant exoplanet that orbits a K-type star known as Epsilon Eridani 10.5 light years away from Earth in the Constellation of Eridanus. These first millimeter interferometer observations of Epsilon Eridani, which hosts the closest debris disk to the Sun, reveal two distinct emission components: (1) the well-known outer dust belt, which, although patchy, is clearly resolved in the radial direction, and (2) an unresolved source coincident with the position of the star. Players interact with each other in a freeform universe, comprising multiple . This allows it to be viewed from most of Earth's surface. Back to list Explore Alien Worlds Exoplanet Travel Bureau Strange New Worlds Historic Timeline In Earth's night sky, however, it is clearly visible to the naked eye as the third closest star viewable without a telescope.
