NASA Exoplanet Archive — Planetary Systems Table documentation

NASA Exoplanet Archive; IPAC / Caltech

Shows why a confirmed planet may have several published parameter solutions and why combining them requires attention to references, methods and uncertainty.

A question to carry into the reading

When two sources give different measurements for one object, what would make the comparison meaningful?

Read the PS table explanation alongside its DOI record. Distinguish all published solutions from the separate composite table before interpreting a value.

Reading and source

This accession is documentation, not a measured planet sample or an archived database. The archive changes over time; retain query time, table, rows and references in any later analysis. Multiple values are not automatically contradictory or erroneous.
