English: Scatter plot of mass, m, and semimajor axis, a, for exoplanet discoveries through 2014-09-23, indicating planets detected using timing:

Estimates (see "important note" below) of m and a are indicated with circles.

Scales indicate (log₁₀ of) mass, m, expressed as Jupiter masses (left) and Earth masses (right); and (log₁₀ of) semimajor axis, a, expressed in AU (bottom), and the corresponding period, p for a planet orbiting a Sun-mass star, expressed in Earth years.

Exoplanet data is from the Open Exoplanet Catalogue,^[1] version 811d352, including some (mostly from the Kepler mission) whose semi major axes are computed from period data. The figure excludes 4 planets with semimajor axes outside the range of the figure and 1 (PSR B1257+12 b) with a mass lower than the range of the figure.

Important note: This figure is intended to serve as a visualization of the catalog of generally accepted candidate exoplanets using the distribution of some of their basic properties related to detection. No attempt has been made to characterize the degree of confidence (which varies widely) in the existence of a given planet or its properties. Nor is any attempt made to convey systematic errors associated with a particular method. In particular, the indicated mass, m, for an exoplanet characterized using radial velocity is the minimum mass (so that the actual distrubiton of masses for non-transiting planets may be shifted and "smeared" significantly upward).
