Last Update: September 1, 2014
The Exoplanet Orbital Catalog (EOC) provides orbital analyses for all confirmed exoplanets. It includes the dimensions of the habitable zone and better estimates of the equilibrium temperature for planets in elliptical orbits. Each thumbnail links to the orbital diagram and the name links to the data of the planet from the Extrasolar Planets Encyclopaedia. Future updates will include other exoplanets databases. The EOC page is under beta test and it will be expanded in the near future. Please send any corrections or suggestions to firstname.lastname@example.org.
All Confirmed Exoplanets
by red boxes
- These figures only focus on the orbital parameters of individual planets and their stars. A 'habitability status' is also included in each figure. Those planets within a red box were updated in the last seven days.
- The figures include the habitable zone (shaded green), the snow line (blue dotted line), and the tidal lock radius (green dotted line). These are not always visible depending on the scale of the figure.
- The habitable zone is calculated from Kopparapu et al. (2014) (ArXiV). More details here and there is an online calculator.
- Equilibrium temperature for elliptical orbits is calculated from Méndez et al. (2014) [in preparation]. All are calculated using an albedo of 0.3 for comparison purposes.
- The size of the tidal lock radius is calculated from Kasting et al. (1993). This is a simple model for only Earth-size planets and future updates will incorporate other models.
- The snow line is calculated from the simple model given in Ida and Lin (2005).
- The criteria for a Habitable Planet Candidate is that the planet orbits (i.e. effective distance) within the optimistic habitable zone and that it has a mass of 0.1 to 10 Earth masses or a radius of 0.5 to 2.5 Earth radii (HEC, 2014).
- The criteria for a Habitable Moons Candidate is that the planet orbits within the habitable zone and is large enough (~10,000 Earth masses) for potential Earth-size or Mars-size moons (Canup & Ward, 2006). This does not consider other problems related to the orbital stability of such moons and tidal effects.
- Please note that not all exoplanets databases include the same orbital solutions for each planet. These figures are from the PHL's Exoplanet Catalog which is mostly based on the Extrasolar Planets Encyclopaedia plus some corrections. Future updates will incorporate data from the NASA Exoplanet Archive and the Exoplanet Data Explorer.
- Current statistics on all exoplanets are available here.
- We already generated similar plots for all >3,600 Kepler candidates, but that is too much data for a single webpage and will require the future implementation of a search feature.
- A future project will focus on the planet physical properties.
