'''Telstar 12''', previously known as '''Orion 2''', is a Canadian [[communications satellite]] in the [[Telstar]] series which is operated by [[Telesat]]. It was originally built for [[Orion Network Systems]], which merged with [[Loral Skynet]] shortly before the satellite was launched. It was subsequently transferred to Telesat when it merged with Loral Skynet in 2007.

Telstar 12 is a [[Ku band|K<sub>u</sub> band]] satellite with coverage of [[North America]] as far west as [[Cleveland, Ohio]], the majority of [[South America]] and [[Europe]]. Telstar 12 also has the capability to provide intercontinental connectivity including [[wikt:transatlantic|trans-Atlantic]] to the [[Mid-East]].<ref name="pamphlet">{{cite web|url=http://www.loralskynet.com/pdf/telstar12_pamphlet.pdf|title=Telstar 12 15° W|publisher=Loral Skynet|archiveurl=https://web.archive.org/web/20120209075653/http://www.loralskynet.com/pdf/telstar12_pamphlet.pdf|archivedate=9 February 2012}}</ref>  [[Eutelsat]] uses four transponders on the satellite for services between Europe and the Americas.<ref>[http://www.eutelsat.org/satellites/15w.html www.eutelsat.org "TELSTAR 12 :: 15° West"] {{webarchive|url=https://web.archive.org/web/20060514232155/http://www.eutelsat.org/satellites/15w.html |date=2006-05-14 }}</ref>
