Hiding just 19 light-years away in the constellation Eridanus is the least-hot star ever observed. The Jupiter-size brown dwarf known as 2MASS 0415–0935 has a surface temperature of a mere 410° Celsius (770° Fahrenheit), only a few hundred degrees hotter than your oven cooking a roast and cooler than a glowing coal.
Its temperature has been measured to be between 24,740 and 33,740 degrees Fahrenheit (14, 000-19,000 Kelvin). Its luminosity ranges from 2,900 to 5,400 times that of the Sun. Shining at magnitude 0.45, its light takes 144 years to reach your eye
