Editing IC 2602 (section)

==Description==
IC 2602 has a total [[apparent magnitude]] of 1.9,<ref name="seds"/> and contains about 75 stars. It is the third-brightest open cluster in the sky, following the [[Hyades (star cluster)|Hyades]] and the [[Pleiades]]. Its apparent diameter is about 50 [[arcminutes]].

IC 2602 is likely about the same age as the [[open cluster]] [[IC 2391]],<ref name="Staffer19972">{{cite journal |author=Stauffer, J.R. |last2=Hartmann |first2=Lee W. |last3=Prosser |first3=Charles F. |last4=Randich |first4=Sofia |last5=Balachandran |first5=Suchitra |last6=Patten |first6=Brian M. |last7=Simon |first7=Theodore |last8=Giampapa |first8=Mark |display-authors=1 |date=1997 |title=Rotational Velocities and Chromospheric/Coronal Activity of Low-Mass Stars in the Young Open Clusters IC 2391 and IC 2602 |journal=Astrophysical Journal |volume=479 |issue=2 |pages=776 |bibcode=1997ApJ...479..776S |doi=10.1086/303930 |doi-access=free}},</ref> which has a [[lithium depletion boundary]] age of 50 million years old,<ref name="Barrado20022">{{cite journal |last1=Barrado y Navascues |first1=D |last2=Stauffer |first2=J.R. |last3=Jayawardhana |first3=R. |date=2002 |title=Spectroscopy of Very Low Mass Stars and Brown Dwarfs in IC 2391: Lithium Depletion and Hα Emission |journal=Astrophysical Journal |volume=614 |issue=1 |pages=386–397 |arxiv=astro-ph/0406436 |bibcode=2004ApJ...614..386B |doi=10.1086/423485|s2cid=208867491 }}</ref> though the age estimated from its [[Hertzsprung-Russell diagram]] is about 13.7 million years.<ref name="webda20172">{{cite web |title=WEBDA page for open cluster IC 2602 |url=http://cbat.eps.harvard.edu/CBAT_M31.html |access-date=2017-04-11 |publisher=WEBDA}}</ref> IC 2602 is thought to form  part of the Lower [[Scorpius–Centaurus association]].<ref name="Whiteoak19612">{{cite journal |last1=Whiteoak |first1=J.B. |date=1961 |title=A study of the galactic cluster IC 2602.
