To date, 5,084 extrasolar planets have been confirmed in 3,811 planetary systems, with another 8,912 candidates awaiting confirmation. These discoveries have provided astronomers with a detailed sampling of the types of planets that exist in our Universe, ranging from gas giants several times the size of Jupiter to smaller, rocky bodies like Earth. So far, the vast majority of these have been discovered using indirect methods – like the Transit Method (Transit Photometry) and the Radial Velocity Method (Doppler Spectroscopy) – while the remainder has been detected using various other means.
