The hottest planet

Nature, 2007
Of the over 200 known extrasolar planets, just 14 pass in front of and behind their parent stars as seen from Earth. This fortuitous geometry allows direct determination of many planetary properties. Previous reports of planetary thermal emission give fluxes that are roughly consistent with predictions based on thermal equilibrium with the planets ...

A planet more, a planet less?

Nature, 2006
Further observations of an object dubbed 2003 UB313, which lies beyond Neptune, show that its diameter is around 3,100 kilometres. This makes it larger than Pluto, the smallest ‘traditional’ Solar System planet. The discovery of the trans-neptunian object 2003 UB313 in July 2005 has rekindled the debate over which objects should be called planets ...

What Is a Planet?

Science, 2001
Cool objects found in young star clusters in Orion and Perseus, such as those reported by M. R. Zapatero Osorio and colleagues in their research article (6 Oct., p. 103), have been described variously as “planetary mass objects,” “isolated giant planets,” “free-floating planets,” and “superplanets” (1).

planet planet gravitational scattering

2010
In planetary systems populated by two or more giant planets, planet--planet scattering can lead to collisions and ejections of one or more bodies. The original planetary configuration can be significantly altered by this kind of dynamical evolution and the presently observed system would be very different from the original outcome of the planet ...

Water on Planets and Dwarf Planets

2011
The classification of objects in the solar system is reviewed. It is outlined that the terrestrial planets, especially Venus, Earth and Mars might have a wet environment during the early evolution of the solar system but in the case for Venus nearly all the water evaporated, and due to climate change, also Mars became a dry planet.

Healing the Planet

Journal of Chinese Philosophy, 2013
Our planet is sick and perhaps on a tipping point of extinction. The causes are well known—global warming, the collapse of the world economy, human greed, and thermonuclear war—to name but a few agents at work in the contemporary world. America and China hold the world’s destiny in their grip. How they will interact is unknown.
