Julio Ángel Fernández
Dr. Julio Ángel Fernández Alves (born Montevideo, 5 April 1946) is a Uruguayan astronomer and member of the department of astronomy at the Universidad de la República in Montevideo. He is also a member of PEDECIBA, (the program for development of basic sciences in Uruguay). From 2005 to 2010, he was the Dean of the Universidad de la Republica's Faculty of Sciences. The asteroid 5996 Julioangel was named after him.
==Kuiper belt==
In 1980, in his paper ''On the existence of a comet belt beyond Neptune'', Fernández proposed that periodic comets arrived too frequently into the inner Solar System to be accounted for solely by having arrived from the Oort cloud, and that a trans-Neptunian belt of comets at around 50 AU would be required to explain them. Subsequent computer models by Martin Duncan, Tom Quinn and Scott Tremaine in Canada supported the view, and led eventually to the discovery of the Kuiper belt. Many astronomers, including David Jewitt, who discovered the belt, believe that Fernández deserves more credit than anyone else, including Gerard Kuiper, for predicting its existence. He has subsequently published many papers on the trans-Neptunian population.〔
