Editing Sextans (section)

=== Multiple star systems ===
Sextans contains a few notable multiple star systems within its boundaries.

[[35 Sextantis]] is a triple star system consisting of two evolved [[K-type giant]]s of equal mass, with both stars being twice as massive as the Sun.<ref name = Tokovinin2008>{{cite journal | last=Tokovinin | first=A. | title=Comparative statistics and origin of triple and quadruple stars | journal=Monthly Notices of the Royal Astronomical Society | volume=389 | issue=2 | date= September 11, 2008 | doi=10.1111/j.1365-2966.2008.13613.x | pages=925–938 | bibcode = 2008MNRAS.389..925T | arxiv = 0806.3263 | doi-access = free}}</ref> The secondary is itself a single-lined [[spectroscopic binary]] consisting of a {{solar mass|0.58|link=y}} companion and itself.<ref name = Tokovinin2008/> The system is located approximately 700 light years away.<ref name = GaiaDR3A>{{Cite DR3|3858258736489909632}}</ref><ref name = GaiaDR3B>{{Cite DR3|3858258736489910400}}</ref> The outer pair has a separation of 6.8" and both stars take roughly 23,000 years to orbit each other while the B subsystem takes 1,528 days to circle each other in a relatively [[orbital eccentricity|eccentric]] orbit.<ref name = Tokovinin2007>{{cite journal | last=Tokovinin | first=A.

There are a few notable [[variable star]]s, including  [[25 Sextantis|25]], [[23 Sextantis]], and [[LHS 292]]. [[NGC 3115]], an edge-on [[lenticular galaxy]], is the only noteworthy [[deep-sky object]]. It also lies near the ecliptic, which causes the [[Moon]], and some of the planets to occasionally pass through it for brief periods of time.

The constellation is the location of the field studied by the [[Cosmic Evolution Survey|COSMOS project]], undertaken by the [[Hubble Space Telescope]].
