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 ...
The data include stellar parameters (such as positions, magnitudes, and temperatures), exoplanet parameters (such as masses and orbital parameters) and discovery/characterization data (such as published radial velocity curves, photometric light curves, images, and spectra).
This is a list of transiting extrasolar planets sorted by orbital periods. As of 2024, 4195 transiting exoplanets have been discovered. [1] This list consist of all transiting exoplanets through 2012, and notable discoveries since. All the transiting planets have true masses, radii and most have known inclinations.
The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods, such as the transit method and the radial-velocity ...
The inclination of exoplanets or members of multi-star star systems is the angle of the plane of the orbit relative to the plane perpendicular to the line of sight from Earth to the object. [ 5 ] An inclination of 0° is a face-on orbit, meaning the plane of the exoplanet's orbit is perpendicular to the line of sight with Earth.
The Exoplanet Archive contains objects discovered through all methods (radial velocity, transits, microlensing, imaging, astrometry, eclipse timing variations, and transit timing variations/TTV) that have publicly available planetary parameters, with a mass (or minimum mass) equal to or less than 30 Jupiter masses.
In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit , values between 0 and 1 form an elliptic orbit , 1 is a parabolic escape orbit (or capture orbit), and greater than ...
An exoplanet that orbits two stars. Double planet: Also known as a binary planet. Two planetary-mass objects orbiting each other. Eccentric Jupiter: A gas giant that orbits its star in an eccentric orbit. Exoplanet: A planet that does not orbit the Sun, but a different star, a stellar remnant, or a brown dwarf. Extragalactic planet
