Astrophysicists Find "Impossible" Planet 436
SpuriousLogic writes "Scientists have discovered a planet that shouldn't exist. The finding, they say, could alter our understanding of orbital dynamics, a field considered pretty well settled since the time of astronomer Johannes Kepler 400 years ago.
The planet is known as a 'hot Jupiter,' a gas giant orbiting the star Wasp-18, about 330 light years from Earth. The planet, Wasp-18b, is so close to the star that it completes a full orbit (its "year") in less than an Earth day, according to the research, which was published in the journal Nature.
Of the more than 370 exoplanets — planets orbiting stars other than our sun — discovered so far, this is just the second with such a close orbit.
The problem is that a planet that close should be consumed by its parent star in less than a million years, say the authors at Keele University in England. The star Wasp-18 is believed to be about a billion years old, and since stars and the planets around them are thought to form at the same time, Wasp-18b should have been reduced to cinders ages ago."

Scientists calculated the weather conditions on a similar "hot Jupiter", HD 189733b, and came up with some pretty amazing results. HD 189733b is locked into synchronous orbit around its parent star in the same manner that the moon orbits the Earth, in that the rotational period directly matches the orbital period (which is fairly common for close orbiting planets, it is very plausible that Wasp 18b could be a similar story), leaving one side of the planet perpetually day, the other perpetually night. As the planet is only 3 million miles from its parent star, it was not overly surprising to find daytime highs of 2,000 - 3,000 degrees Fahrenheit. What was surprising, however, was the nighttime temperature of roughly 1,300 degrees Fahrenheit! This indicates that the atmosphere is incredibly efficient at transferring heat, which means a lot of "air" (NOTE: The atmosphere of HD 189733b is NOT air, but a completely alien mixture of gasses.) moving around. When they calculated the winds that would be necessary to sustain such heat transfer, it was determined that HD 189733b would need to sustain windspeeds of approximately 7,000 mph, making Hurricane Katrina look like a nice ocean breeze by comparison. The weather conditions on Wasp 18b are likely similar; any beings that lived there would indeed have to be extremely tough, and Chuck Norris would most likely be checking his closet for them before going to bed.

From a two-body, Newtonian point-mass analysis, yes the planet can exist. However, a planet that close to a black hole will be affected by Einstein's General Relativity, which predicts a collapsing orbit. Additionally, the planet would be experiencing severe gravitational stresses and magnetic stresses, causing it to break up or its orbit to decay. The other matter collapsing into the black hole would disrupt the "stable" orbit, also causing the planet's orbit to decay or it to break up. In short, I don't think that it is possible to have a long-term stable orbit around an black hole when it is consuming matter.
If you want a bigger plot "hole", think about where the magic gravity beam came from. Why would it come from a black hole? If it came from the planet, then why was it pointed in space?

Okay, I'll bite. What's the difference between a black hole and any other star, from a reasonable distance? A black hole's just a mass, that within a certain distance of the black hole (the Schwarzschild radius) acts very oddly indeed, but outside that distance, acts like any other large mass. A black hole could have the same mass as the Earth (but be the size of a golf ball) and the moon would still orbit it just fine, wouldn't it? It seems to me the main problem the planet would have is that a black hole would be, well, black, so the planet would be as cold as Pluto.
