The four planets Tau Ceti e, f, g and h are considered as strong candidates. [122] HD 10180 has six confirmed planets and potentially three more planets. [123] As a reference, the Solar System has eight verified major planets, alongside multiple dwarf planets (the existence of Planet Nine is yet unconfirmed [124]). System with most planets in ...

This method works best for young planets that emit infrared light and are far from the glare of the star. Currently, this list includes both directly imaged planets and imaged planetary-mass companions (objects that orbit a star but formed through a binary-star-formation process, not a planet-formation process).
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.

The planets were detected by observing small dips in the star's brightness when they crossed in front of it from our vantage point. The innermost planet takes about nine days to orbit the star ...
Tadmor: The radial velocity variations of the star Errai were announced in 1989, consistent with a planet in a 2.5-year orbit. [5] However, misclassification of the star as a giant combined with an underestimation of the orbit of the Gamma Cephei binary, which implied the planet's orbit would be unstable, led some astronomers to suspect the variations were merely due to stellar rotation.
The 2006 IAU redefinition of planet excludes the possibility of double planets. [24] [25] [26] 15760 Albion: 1992 unknown Trans-Neptunian object: When discovered, these bodies were briefly hailed as the tenth and eleventh planets by the press, but it was then decided that 15760 Albion was the prototype of trans-Neptunian objects or cubewanos ...
