Exoplanets Data
Description
Data on planets outside the Solar System.
Usage
data("planets")
Format
A data frame with 101 observations from 101 exoplanets on the following 3 variables.
- mass
Jupiter mass of the planet.
- period
period in earth days.
- eccen
the radial eccentricity of the planet.
Details
From the properties of the exoplanets found up to now it appears that the theory of planetary development constructed for the planets of the Solar System may need to be reformulated. The exoplanets are not at all like the nine local planets that we know so well. A first step in the process of understanding the exoplanets might be to try to classify them with respect to their known properties.
