Werner Landgraf
He also developed a method of eliminating systematic errors in positioning brighter comets that resulted in a more accurate prediction of the Halley's Comet. A recalculation of the path of Halley's comet to 2317 BC confirmed that the Greeks had already seen the comet on 466 B.C.
He discovered seven minor planets including 3683 Baumann, 4378 Voigt (named after Hans-Heinrich Voigt), 9938 Kretlow and 4349 Tibúrcio at ESO's La Silla Observatory in northern Chile.
Halley (song)
The song is in praise of the famous Halley comet and the band's joy with it, with the objective to give a good new, Halley comet could be seen in Earth. This comet only can be seen from Earth every 76 years, and could be seen in 1986, named after the astronomer Edmond Halley.
