  2. Exoplanet orbital and physical parameters - Wikipedia

    en.wikipedia.org/wiki/Exoplanet_orbital_and...

    With the exoplanet sample known in 2009, a group of astronomers estimated that "(1) around 35% of the published eccentric one-planet solutions are statistically indistinguishable from planetary systems in 2:1 orbital resonance, (2) another 40% cannot be statistically distinguished from a circular orbital solution" and "(3) planets with masses ...

    en.wikipedia.org/wiki/NASA_Star_and_Exoplanet...

    The NStED collects and serves public data to support the search for and characterization of extra-solar planets (exoplanets) and their host stars. The data include published light curves, images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets.

  4. List of directly imaged exoplanets - Wikipedia

    en.wikipedia.org/wiki/List_of_directly_imaged...

    Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.

  5. SPECULOOS-3 b - Wikipedia

    en.wikipedia.org/wiki/SPECULOOS-3_b

    SPECULOOS-3 b is an Earth-sized exoplanet, orbiting the ultracool red dwarf star SPECULOOS-3.It is relatively close to Earth, at a distance of 55 light-years. [4] SPECULOOS-3 b takes only about 17 hours to complete an orbit around SPECULOOS-3, and, because of that proximity, it receives very high levels of radiation and is tidally locked, meaning that one side of the planet always faces its ...

  6. Geodynamics of terrestrial exoplanets - Wikipedia

    en.wikipedia.org/wiki/Geodynamics_of_terrestrial...

    Indirect and direct observation methods such as radial velocity and coronagraphs can give envelope estimates of exoplanet parameters such as mass, planetary radius, and orbital radius/eccentricity. Since distance from the host star and planetary size are generally believed to influence exoplanet geodynamic regime, inferences can be drawn from ...

    An exoplanet that orbits two stars. PH1b, Kepler-16b: Circumtriple planet: An exoplanet that orbits three stars. Gliese 900 b: Double planet: Also known as a binary planet. Two planetary-mass objects orbiting each other. OGLE-2017-BLG-0380Lb [2] Eccentric Jupiter: A gas giant that orbits its star in an eccentric orbit. HD 80606 b, HD 20782 b ...

  8. List of exoplanets discovered by the Kepler space telescope

    en.wikipedia.org/wiki/List_of_exoplanets...

    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.

  9. List of exoplanets detected by radial velocity - Wikipedia

    en.wikipedia.org/wiki/List_of_exoplanets...

    The following is a list of 456 extrasolar planets that were only detected by radial velocity method –– 31 confirmed and 323 candidates, sorted by orbital periods. Since none of these planets are transiting or directly observed, they do not have measured radii and generally their masses are only minimum.
