26P / Grigg-Skjellerup is a comet , of 1992 as the second goal of the Giotto probe of ESA was passed only 200 km away. Since the probe sustained camera damage when it encountered Halley , no recordings could be made.
The comet was named after the New Zealand teacher John Grigg and the Australian telegraph technician John Francis Skjellerup . Grigg first discovered the comet on July 23, 1902; Skjellerup rediscovered him in May 1922 from an observation site in South Africa.
Grigg-Skjellerup is the source of pi puppids - meteor shower , which on the southern hemisphere can be observed the Earth around 23 April. In 2003 a new mineral was discovered in this mineral which was named Brownleeit in honor of the astronomer and planetary researcher Donald E. Brownlee .
