'Super' Earth found
Article - 'Super' Earth found (27 Aug.,'04)
http://www.heraldsun.news.com.au/com...55E663,00.html The article says that the planet is ~14 Earth masses, terrestrial, and orbits a sun-like star in less than 10 days. It also says there is debate about whether or not it's in the 'Goldilocks zone' (Goldilocks must be a tough kid :^) Jason H. |

The magic size is called the "tipping point" mass. Which would make Jupiter an oversized Venus no tipping point involved. Or does the height of the atmosphere, not the density, represent the mass of the core? density simply being a consequence of its height. Is there a consistent theory of planetary formation? Or are there just mutulally exclusive WAGs? -- Religions differ in major thinks like eating pork and are the same in minor things like making war. -- The Iron Webmaster, 3222 |

Lets see, what does Earth and this thing have in common... They each orbit a sun-like star. and..., er, that's about it! Oh, it might be a rocky type planet... a very melted rocky type planet. |

Oh, it might be a rocky type planet... a very melted rocky type planet. Yeah, but that last bit is a big deal. It's the first potentially "terrestrial" (meaning rocky, as opposed to gas giant) planet found around another star. The detection threshold is getting lower all the time. Before this it was about the mass of Saturn (95 Earths), now it's 14 Earths. That's a big deal. -- R.G. "Stumpy" Marsh Timaru, New Zealand http://marsh.orcon.net.nz/ S@H 500WU ret. |
