... In addition to the planets and their satellites the solar system contains a large number of smaller but interesting objects. There are thousands of known asteroids and comets and undoubtedly many more unknown ones. ... There are also some asteroids whose orbits carry them closer to the Sun than the Earth (Aten, Icarus, Hephaistos). Most comets have highly elliptical orbits which spend most of their time in the outer reaches of the solar system with only brief passages close to the Sun. ...

The exoplanet HD 209458b has a mass more than 200 times Earthт??s and has a diameter greater than Jupiterт??s. It orbits its star at about an eighth of the distance Mercury orbits the sun, so the exoplanet takes only 3.5 days to complete an orbit. This proximity to a star means that the planet is hot, perhaps 1000ТАC, hence it is classed as a т??hot Jupiterт?? ...
