Epsilon Eridani: 2 planets? and 2 asteroid belts

Let us go on a journey to one of our near galactic neighbours, that of Epsilon Eridani. This is a relatively young star system only about 400 to 800 million years old, and has plenty of interesting things to explore. Let’s find out more. At the right time of year look at the night sky and find Orion the Hunter, here it is. Now just look to the side. This is the constellation Eridanus, and this speck here, visible with the naked eye is Epsilon Eridani. Let’s get aboard our space and time machine for the short journey, just 10.48 light years. Epsilon Eridani is a K type orange star with a diameter 74% and 82% of the mass of our sun. It has just over a third of the luminosity of the sun and a surface temperature of 5000 Kelvin, about 700 degrees cooler than our star.
