Context: <response>: ```Some of the earliest recorded observations wey dem ever make through telescope, na Galileo drawings wey e do on 28 December 1612 and 27 January 1613, get plotted points wey match with wetin we sabi now as the position of Neptune. For both times, Galileo seem say e mistake Neptune for fixed star when e appear close to Jupiter for night sky; so, dem no credit am with Neptune discovery. For e first observation for December 1612, Neptune dey almost stationary for sky because e just turn retrograde that day. This backward motion wey dey happen when Earth orbit carry am pass outer planet. Because Neptune just dey start e yearly retrograde cycle, the motion of the planet too small well well say Galileo small telescope no fit detect am. For July 2009, University of Melbourne physicist David Jamieson announce new evidence wey suggest say Galileo at least know say the 'star' wey e observe don move pass the fixed stars.```
