Editing Terminator (solar) (section)

===Lunar terminator illusion{{anchor|Lunar terminator}}===
The lunar terminator (or tilt) illusion is an [[optical illusion]] arising from the expectation of an observer on Earth that the direction of sunlight illuminating the Moon (i.e. a line [[perpendicular]] to the terminator) should correspond with the [[position of the Sun]], but does not appear to do so. The illusion results from misinterpreting the arrangement of objects in the sky according to intuition based on [[planar geometry]].<ref>{{cite web |last=Jones |first=Christopher B. |title=Lunar Terminator Illusion |url=http://chrisjones.id.au/MoonIllusion/|website=Ellipsis: unfinished thought... |access-date=21 May 2016|date=January 2014}}</ref><ref>{{cite web |first1=Andrea K. |last1=Myers-Beaghton |first2=Alan L. |last2=Myers |title=The Moon Tilt Illusion |url =http://www.seas.upenn.edu/~amyers/MoonPaper20June.pdf}}</ref>
