HEC: Top 10 Lists of Exoplanets

Projects‎ > ‎The Habitable Exoplanets Catalog‎ > ‎

The following tables list the Top 10 exoplanets with respect to mass (M), size (R), density (rho), gravity (g), distance from star (d), period (P), surface temperature (Ts), and distance from Earth (D). Here is a summary of the top ones in all category:

The smallest, less massive and lowest gravity exoplanet so far is PSR 1257 12 b, a pulsar planet resembling Mercury.
The biggest is CT Cha b (probably a brown dwarf) with a radius of 25 Earth radii.
The most massive is CD-35 2722 b with over 10,000 Earth masses.
The less dense is WASP-17 b with only about 10% of water density.
The most dense is KOI-55 b, a dead planet core with over 5 times the density of lead.
The closest to its parent star, with shortest period, and hottest is PSR 1719-14 b, another pulsar planet orbiting at 0.1% of Mercury-Sun distance and with a period of only 2.2 hours.
The farthest to its parent star is WD 0806-661B b orbiting at 63 times Pluto-Sun distance.
The longest period is Oph 11 b taking 2,000 years for one orbit (note that the previous WD 0806-661B b probably takes longer but we don't have its period).
Coldest is GJ 317 c with a temperature of about 50 K (as cold as Pluto).
The closest to Earth is Alpha Centauri B b at 4.3 light years.
The farthest are SWEEPS-04 and SWEEPS-11 at nearly 30,000 light years away.

A similar List of Extrasolar Planet Extremes is available in wikipedia but needs to be updated.

IMPORTANT NOTE: These lists were automatically generated by HEC for all confirmed exoplanets. Radius or mass was estimated when not available from mass-radius relationships. This page is only updated when necessary.
