WASP-18 b

WASP -18 b (also written " WASP -18b ") is an extrasolar planet orbiting the star WASP -18. Its orbital period amounts to less than one day. It is believed that he was probably in a million years in its star crashes into it.

More details

The planet was (in England), who has worked in an international research team discovered on August 26, 2009 by Coel Hellier, astrophysics professor at Keele University, with the help of SuperWASP project.

The one with about 10 Jupiter masses classified as a gas giant planet is about 1 million miles from its star, WASP -18. The mass ratios and the distance to the star imply that the giant planet orbits its star in 0.94 days. The planetary system is about 325 ( another source: 1,000) light-years away from Earth and is located in the constellation Phoenix.

Since act in such a situation as both the star on the planet, tidal forces, this frictional force reduces the velocity of the planet. This is according to calculations lead to the planet will evaporate in an astronomically very short time of 1 million years ago in the central star. Scientists at Keele and the University of Maryland trying to figure out why the planet is not in conflict with its extremely close orbit its star. Because it is extremely unlikely to find a planet that will disappear in such a short time, scientists doubt on the physical assumptions that were made here. They expect to be able to take advantage of the current over the next decade measurements for enlightenment. In our solar system there is a similar case: The Martian satellite Phobos travels approximately 6,000 kilometers from the surface of Mars, needs to orbit around Mars less than eight hours.
