However, much indirect evidence suggests that wet rocky planets are common.

The development of the geologic timescale arose from early nineteenth century fossil correlations and thus firmly rooted in the rock record. The thinking of that time included the possibility that

Statistical Analysis of Solar and Stellar Properties

We review the results of Robles et al. [1] in which a simultaneous multi-parameter comparison of solar and stellar properties and environments is presented. This 11-parameter analysis quantifies the
