One of the earliest and most astounding systems found by direct imaging is the one around the star HR 8799, where four planets range in orbits from beyond that of Saturn out to more than twice the distance of Neptune.

That parts - per - million sensitivity should allow Corot to detect the dips in a star's light caused by a transiting planet with a radius just twice that of Earth — and perhaps an even smaller one, provided its orbit is tighter than Mercury's, so that the planet completes three transits during the 150 - day viewing period.

NASA is particularly interested in identifying planets one half to twice the size of Earth — terrestrial planets rather than the gas or ice giants or hot - super-Earths in short period orbits that evidence suggests exist in large numbers — especially ones that are located in the habitable zone of their stars.

The planet tips the scales at 4.8 Earth masses and is a little less that twice Earth's diameter and the least massive exoplanet to date that has been found orbiting a normal star.
