Lists of planets
Lists of planets are catalogs of which bodies count as planets: the Solar System's eight under the IAU's 2006 definition, and exoplanet lists led by the NASA Exoplanet Archive.
Longitude of the ascending node
The longitude of the ascending node (Ω) is the angle in a reference plane from a reference direction to an orbit's ascending node, one of six orbital elements.
Love number
A Love number is a dimensionless parameter measuring how much a self-gravitating body deforms in response to tidal forces, formulated by A. E. H. Love in 1909.
