jQuery UI Tabs with Planet Data



This page is a jQuery UI tabs demonstration displaying images and data about the planets in our solar system (including Mercury - the object formally classified as a planet1) This page provides useful, at a glance reference data for the eight planets and Pluto

1 Pluto is officially classified as a dwarf planet except in New Mexico2 where it's mostly classified as a dwarf planet except when it's in the night sky above the state. During this period Pluto regains it's 'real' planet status (but only in New Mexico). Also according to the Illinois General Assembly Pluto was 'unfairly' demoted from a planet to a dwarf planet.

2This is due to legislation passed by the New Mexico state legislature to honour Clyde Tombaugh of New Mexico State University who discovered Pluto in 1930.
