The planet was discovered orbiting the [[yellow dwarf]] [[star]] [[COROT-1]] in May 2007. The planet was the first discovery by the [[France|French]]-led [[COROT]] Mission.

| == Detection and discovery ==
| |
| [[Image:Heic0612b H.jpg|thumb|left|200px|Artist's impression of COROT-1b passing in front of its parent star.]]
| |
| The planet was announced by the [[COROT]] mission (a [[CNES]] project with [[European Space Agency]] participation). The planet is a large [[hot Jupiter]], about 1.49 times the radius of [[Jupiter]] and approximately 1.03 times as massive, based on ground observations of the star. Its large size is due to its low density combined with the intense heating of its parent star causing the outer layers of the atmosphere to bloat.
| |
| | |
| == Observation of phases ==
| |
| | |
| In May 2009 COROT-1b became the first extrasolar planet for which optical (as opposed to [[HD 189733 b#Map of the planet|infrared]]) observations of phases were reported.<ref>{{cite journal|title=The changing phases of extrasolar planet CoRoT-1b|journal=Nature|volume= 459|issue=7246|pages=543–545|date=2009-05-28|pmid=19478779|doi=10.1038/nature08045|author1=Ignas A.
