IRAM telescope estimates size of tenth planet
February 1st, 2006
The University of Bonn, using a 30-meter IRAM telescope, have determined that 2003 UB313 has a diameter of 3000 +/- 400 km. Like Spitzer, IRAM measures the heat given off from the object, but IRAM is a much larger telescope than Spitzer. Due to its size, it was able to measure the heat output in a region of the spectrum where much less heat is given off. This new measurement is right in line with the Spitzer measurement, making the tenth planet approximately 125% of the size of Pluto.
