KAT World Science Day 2015 (Solar System & Titan - Exploring an Earthlike World [pdf file] [panosol]

The Solar System - Prologue
The Solar System or solar system consists of the Sun and the other celestial objects gravitationally bound to it: the eight planets, their 166 known moons,[1] three dwarf planets (Ceres, Pluto, and Eris and their four known moons), and billions of small bodies. This last category includes asteroids, Kuiper belt objects, comets, meteoroids, and interplanetary dust.
In broad terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, composed of icy objects. Beyond the Kuiper belt is the scattered disc, the heliopause, and ultimately the hypothetical Oort cloud.


Titan - Prologue
Humans have searched for another Earth practically since coming into existence, at least since we first began to realise that the points of light in the sky were large objects very far away, and the science of astronomy was born. In the modern era, every possible approach, from telescopes and space missions to philosophical arguments, is being used to probe the existence of Earthlike planets elsewhere in the universe.
The ultimate question is whether there is another world sufficiently like ours, with the same temperature conditions and atmospheric composition, where we could live in comfort, or even where life could have developed in a form that we would readily recognise.
