Over the past few years, we have developed the capacity to discover planets orbiting around stars other than the Sun, and the number of detections is increasing exponentially. In the near future, it is likely that Earth-size planets will be discovered, and will need to be compared to observations with similar resolution of the solar system planets, including the only planet that we know to be inhabited, namely the Earth. When observing an extrasolar planet, all the reflected starlight and radiated emission from its surface and atmosphere will be integrated into a single point, and some of its peculiar features will disappear in the noise when global averages are taken. In this chapter, we review the historical and modern observations of the Earth seen as a planet, that is integrating all its emitted and/or reflected light into a single point.
