2006 - Comet Schwassmann-Wachmann 3, one of the comets discovered by astronomers by Arnold Schwassmann and Arno Arthur Wachmann, broke into fragments on its re-entry to the inner Solar System, in a reaction triggered by the Sun's heating the comet as it emerged from the frozen space of the outer Solar System.

1949 - Neptune's moon Nereid is discovered by Gerard Kuiper.

1930 - The dwarf planet Pluto is officially named.

1925 - Birthday, Scott Carpenter, one of the original Mercury Seven astronauts selected by NASA on April 9, 1959. He flew Mercury Aurora 7 and was the second American to orbit Earth and the fourth American in Space.  He has his own website at scottcarpenter.com
