MEarth Project

The MEarth Project (pronounced mirth

transiting planets. As red dwarf stars are small, any transiting planet blocks a larger proportion of starlight than transits around a Sun-like star would, allowing smaller planets to be detected through ground-based observations.[3]

Equipment

The original MEarth-North

Ritchey-Chrétien telescopes equipped with 2048 × 2048 Apogee U42 CCDs, infrared filters, and equatorial mounts.[5]
It began observations in January 2008.[3]

In 2014, the MEarth-South observatory began operations[6] from the Cerro Tololo Inter-American Observatory site east of La Serena, Chile, extending MEarth's coverage to the southern celestial hemisphere using a nearly-identical eight-telescope array.[4] Unlike MEarth-North, the telescopes in Chile are also sensitive to red light.[4]
