SELENE-2 {{IPAc-en|ˈ|s|ɛ|l|ᵻ|n|iː}}, or the Selenological and Engineering Explorer 2, is a cancelled Japanese robotic mission to the Moon that would have included an orbiter, a lander and a rover.{{cite web |url=http://www.asianscientist.com/topnews/japan-announces-selene-2-lunar-mission-2017/ |title=Japan SELENE-2 Lunar Mission Planned For 2017 |author=Srinivas Laxman |date=2012-07-16|access-date= 2012-08-07|work=Asian Scientist}} It was intended as a successor to the 2007 SELENE (Kaguya) lunar orbiter.{{cite web | url=http://www.jspec.jaxa.jp/e/activity/selene2.html | title=Moon lander SELENE-2 | publisher=JAXA Space Exploration Center | date=24 December 2009 | access-date=2010-05-07 | url-status=dead | archive-url=https://web.archive.org/web/20100723055617/http://www.jspec.jaxa.jp/e/activity/selene2.html | archive-date=23 July 2010 }}
